1 Cells, Classification, and Levels of Organization Review-Test Tuesday-2/17 Review due Thursday, 2/12 A. B. Explain the difference between a unicellular and a multicellular organism. A unicellular organisms is made of one cell and a multicellular organism is made of many cells. Give an example of each: Unicellularbacteria and protists. Multicellular plants, animals, and fungi Explain to a friend at least five facts they should know about Protists before they look at pond water under a microscope. They are eukaryotic, microscopic, most unicellular, most heterotrophic, motile, and asexual reproduction. Examples we have studied include: paramecium, amoeba, euglena, and algae Complete the following content frame: Vocabulary Function Found (animal cells, plant cells, or both) Cell membrane Both plant and animal Cytoplasm Both plant and animal Cell wall Plant and fungi too Nucleus Both plant and animal Chloroplasts Plant only Vacuoles Plant and animal lysosomes Gatekeeper of the cell, allows some things in keeps other things out Found in both plant and animal cells Gel-like fluid that gives the cell its shape and has the organelles Found in both plant and animal cells It is like a brick wall, giving support and protection It is found in plant and fungi cells Brain of the cell, contains DNA, controls the functions of the cell Found in both plant and animal cells Captures energy from the sunlight to produce food, chlorophyll is here Found only in plant cells Stores the food, water, and other materials Found in both plants and animal cells Uses chemical to break down food and waste of an animal cell only animal only Draw and label a bacteria cell-include the cell membrane, DNA, cytoplasm, and flagella DNA-floating freely in the cell Cell membrane Flagella Cytoplasm

2 Label the diagrams below Create a venn diagram comparing and contrasting prokaryotic cells and eukaryotic cells Prokaryotic cells Eukaryotic cells No nucleus DNA floats freely inside the cell Simpler cells than eukaryotic Bacteria cells Need energy to survive Nucleus-DNA is enclosed here More complex cell Many organelles Animals, plants, fungi, and protists are all examples

3 Complete the following content frame with the three Domains and six Kingdoms Domain:Archaea Domain:Bacteria Domain:Eukarya Characteristics:prokaryotic Prokaryotic, lives in a normal Eukaryotic lives in a normal Extreme environment environment environment Kingdom Archaeabacteriaprokaryotic, autotrophic and heterotrophic, motile, asexual, unicellular Kingdom Eubacteriaprokaryotic, heterotrophic, motile, asexual, unicellular Kingdom Animalia-eukaryotic, heterotrophic, motile, sexual, multicellular Kingdom Plantae- eukaryotic, autotrophic, sessile, asexual/sexual, multicelular Include whether the kingdom is: Eukaryotic or prokaryotic Heterotrophic or autotrophic Motile or sessile Asexual or sexual Multicelluar or unicellular Kingdom Fungi-eukaryotic, Kingdom heterotrophic, sessile, asexual/sexual, multicellular ingdomkin Kingdom Protista-eukaryotic, most heterotrophic, motile, asexual, unicellular 1. Which kingdoms have organisms with a cell wall? Plantae and Fungi 2. Compare an autotroph to a heterotroph, give an example of each. Autotrophs make their own food(producers)-plants are an example. Heterotrophs(hunt) are consumers, living off of others. Most organisms are heterotrophic(see the above flow chart). 3. Explain the difference between motile and sessile, give examples. When an organism is motile, it can move on its own. Organisms in the Kingdom Animalia are motile, they need to move to get their food as do bacteria and protists. Plants and fungi are both sessile, not capable of moving on their own.

4 4. Identify and write the domain and kingdom of each organism based on their characteristics. Domain Eukarya Kingdom Plantae Domain Archaea Kingdom Archaeabacteria Domain Eukarya Kingdom Protista Domain Bacteria Kingdom Eubacteria Domain Eukarya Kingdom Fungi

5 Domain Eukarya Kingdom Animalia Complete the content frame. Vocabulary word Organism, individual niche population community ecosystem habitat Definition An individual form of life that is capable of growing, metabolizing nutrients, and usually reproducing A shark The function of an organism or population in a community A shark is a predator, consumer A group of organisms of the same species in the same place Many sharks in the Atlantic Ocean, Cape Cod, MA (A herd of sharks) All the populations of different species in a particular area. Sharks, eels, fish, coral, plants A system consisting of all the interactions between abiotic and biotic factors. Biotic, sharks, eels, fish, coral, and abiotic-water, soil, sunlight, air The natural home for an organism, sharks in the Atlantic Ocean biotic All the living organisms-examples sharks, paramecium, algae abiotic All the non-living factors-wind, sun, air, clouds

6 5. Read the passage below and then create a t-chart with the biotic and abiotic factors. The Galapagos Islands are home to the Medium Ground Finch. This small bird lives on the ground and in the lowlands of this volcanic rock island. It avoids the higher forest altitudes. Seeds are the finches main food source, but flowers, buds, leaves, and an occasional insect are eaten. The lowland desert and prickly pear cacti provide spaces for them to build their nests. The finches live in a climate that is cool and dry. Temperatures range from degrees. Abundant rainfall causes more food to be produced that the finches eat. Predators include hawks, snakes, and barn owls. biotic abiotic Medium ground finch, flowers, buds, leaves, insects Prickly pear cacti, seeds Volcanic rock, temperature Rain, altitude Hawks, snakes, and barn 6. Create and label a pyramid to illustrate the levels of organization in an ecosystem. You pick the ecosystems: forest, ocean, rain forest, desert, tundra, or river. 6. Biotic organisms include fishes, squids, jellyfishes, octopi, seaweed, sharks. The abiotic factors include water, air, temperature, sunlight, rocks, etc all non-living! Georgia the fish is dependent on all the abiotic factors in order to survive. Without water, oxygen, sunlight, a constant temperature Georgia and her fish family would die.
