Cells

nucleus

mitochondria

cytoplasm

cell membrane

plasmid DNA

cell wall

vacuole

chloroplasts

flagella

chromosomal DNA (carries most of the genetic information)

Packed with chloroplasts

More chloroplasts near the top of the cell so they're nearer the light

TALL meaning larger SURFACE AREA for ABSORBING CO2 from the air

THIN meaning they can be crammed tightly next to eachother at the top of the leaf

Special kidney-shape

When the plant has lots of water, the cells become TURGID so the stomata OPEN and gases can be exchanged

When the plant is short of water, the cells become FLACCID, making the stomata close, meaning less water vapour escapes.

THIN outer walls and THICKER inner walls make the opening and closing work

SENSITIVE TO LIGHT - CLOSE AT NIGHT to save water
