Specialised Cells Flashcards
How are palisade leaf cells adapted for photosyntheis?
- they are packed with chloroplasts for photosynthesis with most of them being crammed at the top of the cell so they are nearer the light.
- tall shape means a lot of surface area exposed down the side for absorbing co2.
What are guard cells adapted for?
To open and close pores.
Give one way in which guard cells are adapted to open and close pores?
Special kidney shape which opens and closes the stomata (pores) in the leaf.
What are red blood cells adapted for and how do they do this?
They are adapted to carry oxygen by having a concave shape which gives a big surface area for absorbing oxygen. It also helps them pass smoothly through the capillaries to reach body cells.
They are also packed with haemoglobin which is the pigment that absorbs oxygen.
How are sperm and egg cells specialised?
It has a long tail and a streamlined head to help it swim to the egg.
There are lots of mitochondria in the cell to provide the energy needed.
Sperm also carry enzymes in their head to digest through the egg cell membrane.
What are palisade leaf cells adapted for?
Photosynthesis.
