1 Organelle Stations Tuesday, November 12, 2013

2 Welcome! 11/12/13 OBJECTIVE: Students will distinguish between plant and animal cells and practice identifying functions of organelles by cooperatively completing station activities. CATALYST: (HSA Questions) 1. Which cell structure contains molecules that direct cell activities? A. Chloroplast B. nucleus C. Ribosome D. mitochondrion 2. Which organelle in mangrove cells converts solar energy into useable energy? HOMEWORK: A. Nucleus B. ribosome C. chloroplast D. mitochondrion HW 2.1 Organelles DUE Thursday, 11/14/13 Check the class website to try the BONUS RIDDLE

3 Read the question first Catalyst Underline key words Bracket/underline information Identify what topic it is asking about Eliminate answer choices Select the correct answer 1. Which cell structure contains molecules that direct cell activities? A. Chloroplast B. nucleus C. Ribosome D. mitochondrion 2. Which organelle in mangrove cells converts solar energy into useable energy? A. Nucleus B. ribosome C. chloroplast D. mitochondrion

4 Cell Organelle Review For each clue THINK: What organelle could this be? Turn-and-Talk to your neighbor: What organelle do they think it is? What is the function? What characteristic of life does it show?

5 Cell Organelle Review CLUE #1: Organelle made of lipids THINK: What organelle is this? TURN and TALK: What organelle do they think it is? What is the function? What characteristic of life does it show? ANSWER: Cell Membrane Controls what enters and exits the cell Shows sensitivity/homeostasis

6 Cell Organelle Review CLUE #2: Organelle that links amino acids together to make proteins THINK: What organelle is this? TURN and TALK: What organelle do they think it is? What is the function? What characteristic of life does it show? ANSWER: Ribosome Synthesizes proteins

7 Cell Organelle Review CLUE #3: Found in PLANT cells. Requires sunlight THINK: What organelle is this? TURN and TALK: What organelle do they think it is? What is the function? What characteristic of life does it show? ANSWER: Chloroplast Converts solar energy into sugars Nutrition (getting energy)

8 Cell Organelle Review CLUE #4: Used to break down waste particles. THINK: What organelle is this? TURN and TALK: What organelle do they think it is? What is the function? What characteristic of life does it show? ANSWER: Lysosome Breaks down wastes using enzymes Excretion (removing wastes)

9 Cell Organelle Review CLUE #5: Contains nucleic acids. THINK: What organelle is this? TURN and TALK: What organelle do they think it is? What is the function? What characteristic of life does it show? ANSWER: Nucleus Control center for cell activities Sensitivity/Homeostasis (responding to environment)

10 Finish Notes from Yesterday Take out your Cells! Notes from yesterday. (page 2 in your new orange folder) We will be starting on the back, VI. Cell movement & Classification

11 Cell Movement and Classification

12 Cilia Function: Small, hair-like structures that vibrate to help the cell move Analogy: Small vibrating hairs

13 Flagella Function: Whiplike tail that helps the cell move Analogy: Whip /Swimming-Eutreptiella

14 Flagella and Cilia Video cilia

15 Pseudopodia Means false foot Function: moves the cell by RESHAPING itself Analogy: the blob Pseudopodia Pseudo = false pod = foot

16 Video of Amoeba

17 II. Classification of Cells 2 classifications Prokaryotic and Eukaryotic

18 Definitions Pro= before Eu= true Kary = nucleus Prokaryote= before nucleus It is a cell that does not contain a nucleus Eukaryote = True nucleus Type of cell that contains a nucleus and membrane bound organelles

19 Thought Question Looking at your notes about cell organelles, and the diagrams of the plant, animal, and bacterial cells Which of these types of cells are prokaryotes? Which are eukaryotes? What evidence do you have to support your choice?

20 Animal and Plant Cells THE EUKARYOTES

21 Prokaryotic Cells Prokaryotic cells are generally less complex than eukaryotic cells. They do not contain as many organelles, but they are still considered a cell They contain- Cell wall Cell membrane Ribosomes Cytoplasm DNA

22 Cell Organelle Stations You will further explore cell organelles by completing station activities. Stay with your group at each of the 8 stations. You will have 5 minutes at each station stay on task! DO NOT write on any of the cards, models, or booklets!! Station 1: Animal Cell Drawing Station 2; Plant Cell Drawing Station 3: Human Cheek vs. Leaf Cells Station 4: Animal Cell Model Station 5: Plant Cell Model Station 6: Animal Cell under Microscope Station 7: Plant Cell under Microscope Station 8: Structural Comparison of Plant and Animal Cells 5 minutes If you finish early at a station, quiz the other group members about the functions of organelles. Ask, "What is the function of the?" to the others.

23 Stations Wrap-Up What do all of the cells have in common? What were some key differences between plant and animal cells? What organelles did you see?

24 Exit Slip 1. (HSA Question) An organism has cells that contain structures to capture energy from the sun. What are these structures? A. Chloroplasts B. nuclei C. Mitochondria D. Ribosomes 2. Based on your answer to question #1 and your station information, is this cell most likely a plant cell or an animal cell?
