1. Cytoplasm is

a large sac-like structure in plant cells that regulates the water content of the cell a disc-shaped structure containing chlorophyll for photosynthesis a jelly-like material in which biochemical reactions occur in all living cells a thin layer that controls entry and exit of materials to and from a cell

2. The cell wall of a plant cell

is coloured is made of starch is made of cellulose is a thin outer layer

3. Chloroplasts do not

contain chlorophyll make food appear green control the cell

4. Plant cells with many chloroplasts would be found in parts of a plant which

produce food provide storage give support transport materials

5. Onion skin is usually stained with

methylene blue iodine solution water chlorophyll

6. Multicellular organisms are all made of

many cells one cell animal cells plant cells

7. Mitochondria function most like

a pipeline a power plant a packaging plant an instruction book

8. Robert Hooke looked at a piece of cork under a microscope. The little boxes he saw in the cork are called

some text

cells genes nuclei chromosomes

9. Mitochondria

Capture the sun's light energy in animal cells Capture the sun's light energy in green plant cells Release energy from food in animal cells only Release energy from food in all cells

10. The vacuole is
