Cell Structure Pg. 2

Question 1

What are organelles

Answer 1

Organelles are tiny structures that are within the cell

Question 2

Name and explain the function for every organelle found in the typical animal cell

Answer 2

1. Nucleus - contains the genetic material and contains the cell activity
2. Cell membrane - controls what substances goes in and out of the cell
3. Cytoplasm - where the chemical reactions in the cell takes place (contains enzymes)
4. Mitochondria - where aerobic respiration takes place
5. Ribosomes - where proteins are made by protein synthesis
6. Small temporary vacuoles - controls water balance + support
7. glycogen granules - where glycogen is stored

Question 3

Name and explain the function for every organelle found in a typical plant cell

Answer 3

1. Nucleus - contains the genetic material and contains the cell activity
2. Cell membrane - controls what substances goes in and out of the cell
3. Cytoplasm - where the chemical reactions in the cell takes place (contains enzymes)
4. Mitochondria - where aerobic respiration takes place
5. Ribosomes - where proteins are made by protein synthesis
6. Cell wall - rigid structure made of cellulose, supports the cell and strengthens it
7. Chloroplasts - contains chlorophyll which makes food for the cell by photosynthesis
8. Starch granules - where starch is stored
9. vacuole - filled with cell sap which contains water + sugars, controls water balance and supports cell

Question 4

What are the differences in the structure of plant and animal cells

Answer 4

Plants have a cell wall, chloroplasts, starch granules and a vacuole. Animals don’t have a cell wall, don’t have chloroplasts, has glycogen granules and has small temporary vacuoles.
