Leaf Structre and Functions

Summary: Essay provides overview of general leaf structure and functions. To perform its function the leaf must contain chlorophyll and other photosynthetic pigments arranged in such a way that they can absorb light. A leaf must also absorb carbon dioxide and dispose of the waste product oxygen and have a water supply and be able to export manufactured carbohydrate to the rest of the plant.
Leaf structure and their function

The leaf is the main photosynthetic organ in dicotyledons. It has a thin lamina, a midrib and a network of veins. It may also have a leaf stalk (petiole).

To perform its function the leaf must:

  • Contain chlorophyll and other photosynthetic pigments arranged in such a way that they can absorb light.
  • Absorb carbon dioxide and dispose of the waste product oxygen
  • Have a water supply and be able to export manufactured carbohydrate to the rest of the plant
The large surface area of the lamina makes it easier to absorb light, and its thinness minimizes the diffusion pathway for gaseous exchange. The arrangement of leaves on the plant (the leave mosaic) helps the plant to absorb as much light as possible.

A waxy transparent cuticle, which is secreted by epidermal cells, provides the watertight layer. The cuticle and epidermis together form a...
