Practice and Revision - The Leaf
Let us practise and revise what we learned about the leaf. Leaves are important plant parts that carry out photosynthesis, making food for t
Core concept
A leaf has a broad, flat blade to capture sunlight, and veins that transport water and nutrients throughout the leaf.
How it works
The green colour of leaves comes from chlorophyll, a pigment that absorbs sunlight for photosynthesis.
Why it matters
Tiny pores called stomata, usually on the underside of leaves, allow gases like carbon dioxide and oxygen to pass in and out.
Key detail
Leaves come in different shapes and sizes, each adapted to the plant's environment and specific needs.
