Leaf

A primary function of the leaf is to provide nourishment for a plant. Leaves get this by extracting water from the earth and carbon dioxide from the air with the help of sunshine.

Parts of a leaf

Following are the parts of a leaf:

  • The top part of the leaf is the apex or tip that can be round, pointed, and smooth.
  • On most leaves, the lamina, or leaf blade, is the broadest part of the leaf.
  • A petiole is a leaf that links to the plant stem.
  • Stipules, which are little green addendums near the base of the petiole, can also be seen on leaves.
  • Most leaves have a midrib that branches out to initiate vascular tissue veins on the sides.
  • Margin refers to the leaf's outer border, which varies depending on the plant type.
  • At the bottom of the blade, the base is found; it can be flat, heart-shaped, and round.
