Q

Plant cell structure

A

cell wall, cell membrane, nucleus, cytoplasm, vacuole.

17
Q

Cell Membrane; function and describe

A

-retain cell contents and controls what passes in and out of cell.

Describe: The cell membrane is a very thin layer that surrounds the cell.

18
Q

Nucleus: function & describe

A

Its function is to act as the control centre of the cell.
Describe: The nucleus is normally round.

19
Q

Cell wall

A

Function: gives strength to plant
Describe: A cell wall is found outside the cell membrane in plant cells

20
Q

Vacuole: describe & function

A

Describe: contains liquid and if the vacuole is full of liquid, it forces the cytoplasm to push out against the cell wall.
Function: is to give strength to the cell.

21

A

Supplies energy for cell

22
Q

Chloroplast function

A

Makes food (by photosynthesis)

23
