Specialised Cells Flashcards
Why do palisade leaf cells have a tall shape?
A tall shape means a lot of surface area for absorbing CO2, from the air in the leaf
Why do palisade cells have a thin shape?
A thin shape means that you can pack loads of them in at the top of a leaf
Where are palisade leaf cells located?
Palisade leafs cells are grouped together at the top of the leaf where most of the photosynthesis happens
What are guard cells adapted to do?
Guard cells are adapted to open and close pores
How are guard cells adapted to their function?
Guard cells are adapted to their function by allowing gas exchange and controlling water loss with in a leaf
What are red blood cells adapted to do?
To carry oxygen
How is the shape of a red blood cell adapted to carrying oxygen?
A red blood cells concave shape gives a big surface area for absorbing oxygen it also helps then passed smoothly through capillaries to reach body cells.
What are red blood cells packed with and what does this do in terms of oxygen?
Haemoglobin which is the pigment that absorbs oxygen
Why do red blood cells not have a nucleus?
They have no new Kulas to leave even more room for haemoglobin
What are palisade leaf cells adapted for?
Photosynthesis
