Download Cell Processes Review Sheet Photosynthesis: What is the formula

Cell Processes Review Sheet
Photosynthesis:
1. What is the formula for photosynthesis (write the chemical equation):
Light Energy + 6CO2 + 6H2O→ C6H12O6+6O2
2. The products of photosynthesis are: glucose and oxygen
3. The reactants of photosynthesis are: sunlight, carbon dioxide, and water.
4. Where does each of the reactants come from and how are they transferred?
Energy→ Sun; CO2→ Atmosphere (through the stoma/pores in the leaves);H2O→Ground
( through the roots).
5. Where does each of the products from photosynthesis end up and how are they
transferred?
Some glucose is used by the plant and some glucose is stored .
Oxygen is released into the air by the stoma.
6. What type of cell(s) undergoes photosynthesis? Which organelle is involved?
Plant cells
/ Chloroplasts
Cellular Respiration:
7. What is the formula for cellular respiration (write the chemical equation):
C6H12O6 + 6O2
6H20+6CO2 +ATP
8. The reactants of cellular respiration are GLUCOSE and OXYGEN.
9. The products of cellular respiration are: WATER, CARBON DIOXIDE ,and ATP/Energy
10. Where does each of the reactants come from and how are they transferred?
*Glucose comes from food and is transferred active or passive transport
* Oxygen comes from the air and is transferred through the cell membrane.
11.Where does each of the products end up and how is it transferred?
*Water is released from the cell through OSMOSIS
*CO2 is released from the cell through DIFFUSION.
*ATP –some is used by the cells; some released as heat.

12. What type of cell(s) undergoes cellular respiration? Which organelle is involved?
Plants and animals cells undergo cellular respiration. Mitochondria is the organelle involved.
13. How are photosynthesis and cellular respiration related?
* Photosynthesis provides reactants for cellular respiration; cellular respiration provides
some of the reactants for photosynthesis. ( Depend on each other)
Active and Passive Transport:
14. Which particles travel through the cell by active and passive transport?
Particles that are TOO BIG such as sugar and amino acids travel by active and
transport.
passive
15. What organelle is involved in the process?
Cell Membrane
16. What is the difference between active and passive transport?
*Active Transport uses energy because it goes in direction from low concentration to high
concentration.:
*Passive Transport – does not need energy because it goes in direction from an area of high
concentration to low concentration.
17. Osmosis and Diffusion:
Diffusion is the spreading out of particles from HIGH to LOW concentration.
This occurs across the CELL MEMBRANE. Does diffusion require energy? NO
Osmosis is the diffusion of WATER.
