What is the Function of Plumule?
Function of plumule in seed include include:
- Initiation of Shoot Growth: Upon germination, the plumule gives rise to the embryonic shoot system, which eventually develops into the stem, leaves, and reproductive structures.
- Photosynthesis: The embryonic leaves within the plumule serve as the first sites of photosynthesis in the emerging seedling, providing energy for growth and metabolism.
- Apical Dominance: The apical bud at the tip of the plumule exerts apical dominance. This refers to the apical or upward growth of the plant and the inhibition of lateral buds. This promotes vertical shoot elongation.
- Developmental Signaling: The plumule secretes hormonal signals and growth regulators that coordinate the development of the shoot system and mediate responses to environmental cues.
Plumule of Seed
The plumule is the part of the embryonic structure found within the seed of a plant. It is a bud-like structure that serves as the precursor to the shoot system of the plant. The plumule in plants consists of the embryonic shoot apex, which contains meristematic tissue capable of giving rise to the plant’s stem, leaves, and other aerial parts. In this article, we will look into the meaning, location, features, and functions of plumule.
