What process is palisade mesophyll specialised for?
Photosynthesis.
What are the shape and arrangement of palisade mesophyll cells?
They are elongated and closely packed.
How are palisade mesophyll cells adapted to absorb light?
They contain many chloroplasts.
Where is palisade mesophyll located in a leaf?
Near the upper surface.
Through which leaf tissue does light pass to reach the palisade mesophyll?
The epidermis.
How are spongy mesophyll cells arranged in a leaf?
They are loosely arranged, with large air spaces between them.
How do air spaces in the spongy mesophyll help gases diffuse through a leaf?
They allow carbon dioxide to reach photosynthesising cells, and oxygen and water vapour to move towards the stomata.
What is the role of chloroplasts in spongy mesophyll cells?
They enable the cells to carry out photosynthesis.
How does the number of chloroplasts in spongy mesophyll cells generally compare with that in palisade cells?
Spongy mesophyll cells generally have fewer chloroplasts.
What type of cells does meristem tissue contain, and what can they continue to do?
Unspecialised cells that can continue to divide by mitosis.
Where are the meristems that support root and shoot growth located?
At the growing tips of roots and shoots.
How do meristems support the growth of roots and shoots?
They produce new cells, allowing these regions to grow.
What can new cells produced by meristems become as a plant develops?
They can differentiate into specialised plant cells, supplying tissues needed for development.
