Given these characteristics of life, which of the following objects is considered a living organism? W. X. Y. Z. X W C. Y D. Z 2. Prokaryotic and eukaryotic cells have many differences, but they also share some common features. Which of the following may be found in either type of cell? cell walls nuclei C. mitochondria D. Golgi bodies

2 3. All living organisms share many characteristics necessary for life. For example, all organisms, including both prokaryotic and eukaryotic, must obtain and use energy for life processes. have cells arranged into complex organ structures. can sexually reproduce to produce unique offspring. C. can use abiotic factors to make their own food. D. 4. Both eukaryotic cells and prokaryotic cells possess DNA and engage in genetic processes. Which of the following is true of their cellular genetics? Prokaryotic DNA cannot be translated into proteins because of the lack of a nucleus. Eukaryotic DNA is linear, whereas most prokaryotic DNA is circular. Eukaryotic and prokaryotic DNA use different genetic codes (i.e. nucleotides). C. Eukaryotic cells generally require fewer genes to operate than prokaryotic cells. D. 5. Mitosis is the cellular reproduction process which produces two genetically identical daughter cells from one parent cell. Mitosis occurs all over our bodies, replacing dead cells and keeping tissues and organs functioning properly. Mitosis cannot occur until the genetic material inside of a cell has been copied. Where in the cell is this genetic material located? in the cell membrane in the vacuole C. in the Golgi complex D. in the nucleus

All living things are able to move. C. All living things are complex. D. All living things are made of cells. 24. What are the most basic building blocks of all organisms? cells muscles C. bones D. organs 25. Which of the following is true about cells? In general, prokaryotic cells do not have a true nucleus or membrane-bound organelles, whereas eukaryotic cells contain both a nucleus and organelles enclosed by membranes. Both eukaryotic cells and prokaryotic cells always contain both a true nucleus that is well-defined and organelles that are separated from the cytoplasm by membranes. C. Neither prokaryotic cells nor eukaryotic cells ever contain both a true nucleus that is well-defined and

The only object that meets all of the given characteristics of life is the plant. Batteries, rocks, and seashells are not living organisms. 2. Prokaryotic cells do not possess true nuclei or any other membrane-bound organelles. They do, however, possess plasma membranes, cytoplasm, cell walls, ribosomes, and DN Eukaryotic cells can possess all of these features, too. 3. All living organisms must have an organized structure, obtain and use energy and materials, maintain homeostasis, grow, reproduce and pass on genetic information, and respond to stimuli and evolve/adapt to their environment. Not all living organisms have complex structures such as organs, can make their own food, or can sexually reproduce. Prokaryotic organisms, for example, are single-celled and can only reproduce asexually. 4. Both eukaryotic and prokaryotic cells possess DNA constructed from the same genetic code (i.e. the same four nucleotides - A, T, C, G). However, eukaryotic DNA is linear, organized into chromosomes, and packaged in nuclei for greater efficiency, whereas most prokaryotic DNA is circular and free-floating in the cytoplasm. There are a few cases in which prokaryotes possess linear DNA, but this is more the exception than the norm. Both cells also possess ribosomes which enable them to perform protein translation.

11 5. The cell's nucleus acts as the "control center" of the cell, directing the cell's growth and development. It houses the genetic material of the cell, and this material must be duplicated before mitosis, one form of cell reproduction, can occur. 6. Most large organisms, such as plants and animals, are eukaryotes, although in a few instances, some microscopic protists are eukaryotic as well. So, in general, eukaryotes are much larger than prokaryotes. In addition, there are significant differences between the cells of eukaryotes and prokaryotes. Eukaryotic cells are generally larger and more complex than prokaryotic cells. This is because eukaryotic cells contain many membrane-bound organelles. Prokaryotic cells, on the other hand, do not contain any membrane-bound organelles. However, they do possess ribosomes, which are non-membranous complexes of protein and RN The ribosomes in prokaryotic cells have less RNA and fewer proteins than do eukaryotic ribosomes. 7. Organisms differ from each other in many ways. This diversity ranges from simple prokaryotic cells to complex multicellular organisms. The diagrams demonstrate how cell structure can be used to differentiate organisms. Organisms may also be classified using other factors, including their cell number, their mode of nutrition, their means of movement, and their method for reproduction. 8. The most fundamental difference between prokaryotic and eukaryotic cells is the presence or absence of a true nucleus and membrane-bound organelles, such as mitochondria and chloroplasts. Eukaryotes have them; prokaryotes do not. In fact, the name prokaryote means "before a nucleus". 9. Ribosomes are RNA and protein complexes that are found in all cells. These complexes help cells during protein translation by joining amino acids together to form polypeptides. Ribosomes are composed of two subunits. These subunits attach to and travel along strands of mrna during translation. As the anticodons on trna molecules attach sequentially to the codons on an mrna strand, the amino acids carried by the trna molecules take up the proper position to be joined by peptide bonds and form a polypeptide. 10. According to cell theory, all living things are composed of cells. Some have only one cell, others have many cells, but the way in which cells function is similar in all living organisms. Cell theory also states that cells are the basic unit of structure and function in living things, and new cells are produced by existing cells. 11. Prokaryotic cells are fairly small, simple cells. However, since they are only found in unicellular organisms, they are versatile enough to provide for all of an organism's functions. Still, since they lack nuclei and membrane-bound organelles, they are less efficient than eukaryotic cells. Eukaryotic cells are found in both unicellular and multicellular organisms. These cells tend to be larger, more complex, and require more genes to operate than prokaryotic cells. 12. Cells have characteristic structures and functions that make them distinctive. Organelles are the membrane-bound structures found in eukaryotic cells that play important roles, such as maintaining homeostasis and aiding in cell reproduction. All of the other answer choices listed are types of organelles. 13. All living organisms are composed of one or more cells.

12 All of the other listed characteristics are true of some living organisms but not all living organisms. For example, only plants and some microorganisms perform photosynthesis, and only eukaryotes contain specialized membrane-bound organelles. 14. The nucleus of the cell stores information in the form of DN The DNA inside the nucleus directs the cell's growth and development. Because DNA controls all of a cell's major functions, the nucleus containing the DNA is considered the cell's control center. 15. The life forms exhibiting the simplest cellular structure are prokaryotes. They exist in two major forms: eubacteria and archaebacteria. Prokaryotes were first life forms to develop on Earth and are the most abundant inhabitants. They can survive in a wide range of environments and obtain energy in a variety of ways. 16. The structures of cellular organelles are related to their functions. For example, many chemical reactions occur in the mitochondria in order to provide the cell with energy. Having a highly folded inner membrane increases the surface area upon which these reactions can occur. Vacuoles, on the other hand, must be able to easily expand and contract as water moves in and out. Thus, a single-layer membrane is necessary to support the vacuoles' function Cells are the basic building blocks of all living organisms. Cells contain smaller, specialized structures called organelles, which carry out specific functions in the cell. Organisms can have one cell (unicellular organisms) or more than one cell (multicellular organisms). 19. The picture shows a human heart which can be classified as an organ. 20. The Golgi apparatus processes, sorts, and modifies proteins in a cell. In fact, the formation of complex biomolecules is possible because of the modifications that proteins undergo while they are moved through the Golgi apparatus. The Golgi apparatus also processes and transports materials, including wastes, out of the cell. Thus, the Golgi apparatus plays an important role in waste disposal. 21. Water is the single most abundant compound in all living organisms. In fact, about two-thirds of the weight of cells is accounted for by water. Water is what gives cells so many of their properties In addition to the other named criteria, all living things are composed of cells. Although some living things are complex or intelligent and some living things can move, these are not requirements for all living things. 24. All living things are made of one or more cells. Cells are the basic building blocks of all organisms. Bones, muscles, and organs are all made up of cells organized in different levels of complexity. 25. Prokaryotic cells do not have a true nucleus or membrane-bound organelles. Prokaryotic organisms are usually unicellular. Eukaryotic cells have nuclei and organelles that are separated from the cytoplasm by membranes. Eukaryotic

13 organisms are usually multicellular. In general, prokaryotic cells do not have a true nucleus or membrane-bound organelles, whereas eukaryotic cells contain both a nucleus and organelles enclosed by membranes. 26. Many cellular processes are the same across the plant and animal kingdoms. Organisms in these kingdoms have developed similar structural specializations for supporting these cellular processes. Specifically, a version of respiratory, skeletal, circulatory, and reproductive tissues, organs, and organ systems can be found in most multicellular organisms. 27. Membrane organelles known as lysosomes contain enzymes specialized to break down ingested materials, secretions, and wastes. Lysosomes, along with the Golgi complex, are responsible for the disposal of cellular waste within a cell. 28. The specialization of cells in multicellular organisms is usually due to different patterns of gene expression rather than to differences of the genes themselves. However, what causes cells with similar genes to differentiate into unique cell types is not fully understood. It may be due to the presence of different environmental conditions that signal some genes to be expressed while other genes remain dormant. It may be due to internal regulators or any of a number of factors that researchers are currently studying. Think of it this way: you and three friends are each given 10 cards with the same letters on them (i.e., you all have the same genes). However, you each choose to use the letters to spell four different words (i.e., you each expressed your genes in a different way). No one knows why you each chose to arrange your letters in different ways despite being given the same set of starting letters, but the end result is four different words (i.e., specialized cells). 29. When a group of cells work together, such as in bones, muscles, or nerves, they are known as a tissue. Tissues include bone, blood, nerves, muscles, and skin. A group of tissues that work together, such as the muscles that make up the heart, form an organ. 30. All living organisms must have an organized structure, obtain and use energy and materials, maintain homeostasis, grow, reproduce and pass on genetic information, and respond to stimuli and evolve/adapt to their environment. Although viruses contain DNA and pass their DNA on to their offspring, they cannot do this unassisted, nor do they meet all the other criteria for living organisms. Thus, viruses are not considered to be living organisms.
