Photosynthesis: CO2+ H2O + Sunlight àC6H12O6 (sugar) + O2

Unit 3 Test Study Guide
1. What is shown?
2. What does it do?
Photosynthesis- makes sugar
3. Write the equations for photosynthesis and cellular respiration
Photosynthesis: CO2+ H2O + Sunlight C6H12O6 (sugar) + O2
Cellular Respiration: C6H12O6 (sugar) + O2  ATP + H2O + CO2
4. How are the products and reactants related?
They are opposites. The reactants of photosynthesis are CO2+ H2O , the products made by cellular respiration. The
reactants of cellular respiration are the products of photosynthesis.
5. The depth at which algae were found in a lake varied from day to day. On clear days, the algae were found as
much as 6 meters below the surface of the water but were only 1 meter below the surface on cloudy days. Why?
Algae need sunlight to photosynthesize, on sunny days the UV rays from the sun will penetrate the water to 6
meters. On cloudy days for the algae to get sun rays it must be very close to the surface.
6. Define – Aerobic respiration: Breaking down glucose to release ATP using Oxygen
7. Define – Anaerobic respiration: Breaking down glucose to release ATP NOT using Oxygen
-What are 2 types? Alcoholic Fermentation and Lactic Acid Fermentation
8. Label the pictures with the process that is occurring:
Anaerobic Respiration= Alcoholic
Aerobic Respiration
Nothing, no glucose
Nothing, no yeast
9. When oxygen is unavailable what process will occur? (two possibilities)
Alcoholic Fermentation and Lactic Acid Fermentation
-What will the product be?
Alcohol and CO2, or Lactic Acid in animals
10. Is glucose organic or inorganic?
11. Many cell functions and processes require energy in the form of ATP
12. Describe what would happen in each scenario:
created by
cellular respiration
Osmosis- High (100) to
Low (95), water enters
membrane bag
Osmosis- High (95) to
Low (80), water
leaves the membrane
Nothing HappenedEquilibrium
13. Movement of molecules from…
Low to high is Active
High to low is Passive
14. Red blood cells with 90% potassium exist in your blood (which is 40% potassium concentration), how does the
cell maintain the high concentration?
Active Transport, it wants to keep a high concentration so it must pump potassium against the concentration
15. Draw a cell membrane and label phospholipids and proteins:
16. Label this plant cell:
Cell Wall
Vacuole (or cytoplasm)
17. Which cell structures are found in every living cell?
a. Chloroplasts and mitochondria
b. Centrioles and chromosomes
c. A cell wall and nucleus
d. A plasma membrane and cytoplasm
18. Define the function of each of the following:
a. Nucleus – hold DNA which codes for proteins
b. Chloroplast – makes sugar (glucose), site of photosynthesis
c. Centriole – Aids in Cell Division in animals
d. Lysosome – Carries digestive enzymes
19. Mitosis produces how many cells?
a. Are the cells genetically the same or different?
2- genetically the same, both diploid
20. Name 4 types of asexual reproduction:
Budding (1 big, 1 small), Binary Fission (2 same size cells), Vegetative Propagation, Regeneration
21. Asexual reproduction occurs through the process of
22. Binary fission produces 2 cells, are they the same size? Yes
23. Budding produces 2 cells, are they the same size? No, one big, one small
24. What is cancer? Uncontrolled cell division (mitosis)
