1. Cell Processes
Study Guide Review

2. Warm Up
Use your notes to answer questions 1-5 on your Study Guide.

3. # 1
Diffusion is the movement of particles from areas of high concentration to areas of low concentration, however, osmosis is the diffusion of water through a semipermeable membrane.

4. #2
Exocytosis is a type of active transport where the cell removes large particles from the cell.
Endocytosis is the opposite of exocytosis because large particles are brought in instead of removed.

5. #3
3. Plants use photosynthesis to make glucose. 4. During cellular respiration, oxygen is used to break down food molecules releasing large amounts of energy. 5. Mitosis is when the nucleus and chromosomes are dividing. Cytokinesis is when the cell membrane (animal and plant) or the cell wall (plants) is dividing.

7. 6. Active transport requires energy and passive transport does not. 7
6. Active transport requires energy and passive transport does not. 7. Cellular respiration creates energy using oxygen and photosynthesis uses carbon dioxide and water to produce glucose and oxygen. 8. C 9. A

8. 10. D 11. C 12. Endocytosis and Exocytosis are both examples of active transport which requires energy because the particles are either too large to go through the cell membrane or are moving against the concentration gradient. 13. Photosynthesis happens in the chloroplast and cellular respiration occurs in the mitochondria.

9. #14 Interphase: Chromosomes are copied. Mitosis
Prophase – Chromosomes condense into rod like structures
Metaphase – Chromosomes line up in the middle
Anaphase – Chromosomes separate to opposite ends
Telophase – Nuclear membranes form and chromosomes unwind
Cytokinesis – Cell wall or membrane is formed (depends on the type of cell)

prophase
Chromosomes pair up
Metaphase
Chromosomes meet in the middle
Anaphase
Chromosomes start to pull apart
