The Leaf Structure. Flashcards
What’s the waxy layer used to control the amount of water entering and leaving the leaf.
Waxy cuticle.
How are minerals transported into a leaf?
How is water transported into a leaf?
Minerals- active transport.
Water- osmosis.
What happens in the spongy mesophyll layer?
captures light and makes food. Spongy mesophyll cells have air spaces between them to allow easy gas exchange.
What dose the stoma do?
It allows gas exchange; since a lot of water vapour can be lost through the stomata they only open for photosynthesis in daylight; at night they close to reduce loss of water vapour.
What happens in the palisade mesophyll?
These cells are tall and closely packed to absorb maximum light. They contain many chloroplasts. Most photosynthesis takes place in the palisade cells.
