Question 1

food production in plants

Answer 1

plants produce their own food thanks to chloroplasts which do photosynthesis

Question 2

food storage in plants

Answer 2

when a plant produces more food than it needs, it converts excess glucose (sugar) into starch for storage purposes (stored in roots and leaves)

Question 3

Structural differences between plant and animal cells

Answer 3

• plant cells are made of chloroplasts (do photosynthesis) and cellulose (make up the cell wall)
• animal cells are made of centrioles (structural support) and only has cellular membrane

Question 4

how to tell between plant and animal cells

Answer 4

animal cells have round structure and freestanding
plant cells are compact and have a cell wall

Question 5

The purpose of staining cells

Answer 5

• darkens the cell structure, allowing you to see them better (kills the cells)

Question 6

What was responsible for the coloration in the various plant cells we observed

Answer 6

chlorophyll, central vacuole, plastids

Question 7

Explain the mechanism by which plants exchange gasses

Answer 7

exchanges of gasses occur thanks to the stomata of plants that are made up of 2 guard cells containing chloroplasts (produce food therefore control opening and closing)
