What is in a plant cell?
cell wall, vacuole, chloroplasts, a nucleus, cytoplasm, call membrane, mitochondria and ribosomes
2 of 12
What is in a yeast cell?
A nucleus, cytoplasm, a cell wall and a cell membrane
3 of 12
What is in a bacterial cell?
Cytoplasm, a cell membrane, a cell wall and NO nucleus
4 of 12
Where is the genetic material held in a bacterial cell?
In the cytoplasm because a bacterial cell doesn't have a nucleus

How are palisade leaf cells adapted for photosynthesis?
More chloroplasts are crammed at the top of the leaf, so they are closer to the light. Their tall shape means more surface area along the side for absorbing carbon dioxide.

How are guard cells adapted to open and close pores in a leaf?
Their kidney shape opens and closes the stomata (pores). When the plant has a lot of water the guard cells become turgid to make the stomata open so gasses can be exchanged for photosynthesis.

How are guard cells adapted to open and close pores in a leaf? pt.2
When the plant is short of water, guard cells loose water making the stomata close, this helps stop too much water vapour escaping. The thin outer and thicker inner walls make the opening and closing work.

How are red blood cells adapted to carry oxygen?
Their concave shape gives them a bigger surface area for absorbing oxygen and to help them pass through capillaries smoothly. They are packed with haemoglobin - to absorb oxygen. They have no nucleus so there is more space for the haemoglobin.
