which type of
leaf is this?
Answers
Answer:
A leaf is a structural component of a plant in the form of an appendage. Leaves perform several essential functions for the growth and maintenance of a plant. The primary function is to perform photosynthesis, a process that transforms solar energy, water, and carbon dioxide into food for the plant. Other functions of a leaf include transpiration (release of water), guttation (release of water on the leaf margins), and storage of water and nutrients. In some plants, leaves have spines as a defense or protection. An example of leaf spines is found on the prickly pear cactus.
The structural parts of a leaf are shown in the leaf diagram and explained below:
Midrib: the primary center vein of a leaf
Veins: the individual lines on a leaf that help transport materials
Margin: the edge or boundary of a leaf
Leaf base: the bottom of the leaf where it attaches to the petiole
Petiole (not shown): long, narrow stalk that attaches the leaf to the stem
Lamina: (not labeled) the surface of the leaf; also known as the leaf blade
Stipules (not shown): small pair of leaf-like structures at the base of the petiole
