At the completion of this unit students will be able to: A. Describe

Stomata

Leaf Is typically a large, flat, green organ attached to the stem. Leaves carry out photosynthesis, transpiration, and may store food. Shape, arrangement, and other features vary widely with the species of plant.

Kinds of leaves a. Simple—A simple leaf has only one blade. b. Compound—A compound leaf is divided into two or more leaflets

Leaf attachment This refers to the spacing and arrangement of leaves on the stem of a plant. The major kinds of attachment are: (1) Alternate—Alternate leaf arrangement is one leaf at each node on a stem.

(2) Opposite—Opposite leaf arrangement is two leaves are attached at nodes opposite each other.

(3) Whorled—Whorled leaf arrangement is three or more leaves are at each node.
