3. I can identify the structures in plant and animal cells.

Fill in the Venn Diagram below using the word list above:

Plant Both Animal

4. I can explain the characteristics and role of the cell membrane 10. What are cell membranes composed of? 11. What does it mean for a cell membrane to be semi-permeable? 12. Label the diagram below:

5. I can distinguish between active and passive transport. 13. What is the following process called?

14. What does it mean for a particle to move against a concentration gradient? What kind of transport is required? 15. What is the difference between osmosis and diffusion? Write two examples for each.

mitochondria ribosome chloroplast nucleus cell wall lysosome large vacuole cytoplasm rough ER cell membrane nucleus golgi apparatus eukaryote ribosomes carries out photosynthesis carries out cellular respiration

6. I can predict the movement of substances across the cell membrane. 16. Draw a picture of a cell in a hypotonic environment and predict the movement of water with an arrow. 17. In the potato lab, why did the potatoes left in the salt water weigh less after two days? Draw a picture to explain your answer, and talk about the solute concentration in your answer. 18. If the solute concentration inside a cell is higher than the concentration outside a cell, is the cell hypotonic or hypertonic? Will water move into the cell or out of the cell? 7. I can summarize how photosynthesis and respiration are mechanisms for obtaining energy. 19. What are the reactants and products of photosynthesis? 20. What are the reactants and products of cellular respiration? 21. When do plants go through respiration? Complete the sentences: Whether or not oxygen is present, the first step of respiration is always 22______. Along with 2 ATP, this process produces two 23 ______ molecules from glucose. If 24_______ is present, more than 30 ATP are made through 25 ________ respiration. In 26_________ respiration, fermentation occurs and produces either 27_______ or 28_______ as a byproduct. 29. Write your own paragraph (similar to the one above) describing photosynthesis. Make sure to use the words: carbon dioxide, water, oxygen, glucose, chloroplast, chlorophyll, thylakoid, ATP, sun light 8. I can describe the relationship between photosynthesis and respiration in the carbon cycle. 30. How are photosynthesis and respiration related to the carbon cycle? Use the data table below to answer the following questions: Test Tube A B C D E F G H
