Leaf Function and Structure
- The primary function of a leaf in a vascular plant is to carry out photosynthesis.
- The primary photosynthetic tissue in most leaves is the mesophyll, which is composed of palisade and spongy cells.
- Leaves owe their green color to the presence of chlorophyll, a green pigment that absorbs sunlight and plays a crucial role in photosynthesis.
- Leaves with distinct upper and lower surfaces that differ in color, hairiness, and other features are known as dorsiventral leaves.
- The broad, flat leaves with complex venation of flowering plants are known as megaphylls.
