Answers
Answer:
The arrangement of veins in a leaf is called the venation pattern; monocots have parallel venation, while dicots have reticulate venation. The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.
Explanation:
Leaves have two main parts: The leaf blade and the Stalk or the petiole. The leaf blade: It is also called the lamina. It's generally broad and flat. ... The petiole: It is the stalk-like structure which connects the leaf blade to the stem.
Phyllotaxy (phyllotaxis) is the mode of arrangement of leaves, scales, or bracts with flowers along the plant stem. Phyllotaxy research deals with the study of biological pattern formation (morphogenesis); it answers questions such as what the shoot apical meristem (SAM) does and how it does it.
Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral. Alternate leaves alternate on each side of the stem in a flat plane, and spiral leaves are arranged in a spiral along the stem.
