Palisade leaf cells

They are adapted for photosynthesis.

1)they are packed with chloroplasts for photosynthesis. More of them are crammed at the top of the cell so they are nearer the light.

2)Large surface area- therefor alot of CO2 can be absorbed

3)Thin -therefor you can pack more into a cell.

Guard cell

Guard cells are adapetd to open and close

1)special kidney shape which opens and closes the stomata (pores)in a leaf

2)When the plant has alot of water the stomata opens so gases can be exchanged for photosyntheis.

3)When it is short of water the guard cells lose water and become flaccid, making the stomata close

Red Blood Cells

Red Blood cells are adapted to carry oxygen

1)Concave shape gives them a big surface area for absorbing oxygen

2)they are packed with haemoglobin-the pigment that absorbs the oxygen
