Q

What do chloroplasts do?

A

Chloroplasts are green cells that most plant cell contains. They are green because they contain clorophyll which absorbs light so the plant can make food by photosynthesis

Q

What is the permanent vacuole and what does it do?

A

The large permanent vacuole is a space in the cytoplasm filled with cell sap. This is important for keeping the cell rigid to support the plant.

Q

What do plasmids do in a bacteria cell?

A

They carry genes that are usefull and pass them to other bacteria cells.

17
Q

What does the single strand of DNA do in a bacteria cell?

A

Carries DNA.

18
Q

What does the flagellum do in a bacteria cell?

A

Helps the cell in movement

19
Q

What does the slime capsule do in a bacteria cell?

A

It protects the cell from physical and chemical attacks

20
Q

What does the plasma membrane do in a bacteria cell?

A

The plasma membrane regulates the transport of materials entering and exiting the cell.

21
Q

What does the cell wall do in a becteria cell?

A

confer the characteristic cell shape and provide the cell with mechanical protection.

22
