Features of Plumule
The plumule has several distinctive characteristics that set it apart from other parts of the seed embryos. These are:
- Embryonic Shoot Apex: At its core, the plumule comprises the embryonic shoot apex—a region of undifferentiated cells capable of giving rise to the shoot system of the mature plant.
- Embryonic Leaves and Photosynthesis: The plumule contains immature leaves, known as cotyledons or seed leaves. These embryonic leaves serve as the first photosynthetic organs of the emerging seedling.
- Meristematic Tissue: The plumule contains actively dividing meristematic cells, which leads to the development of the shoot apex.
- Phototrophism: Since the plumule develops into the shoot, it shows positive phototrophism and grows towards light.
- Geotrophism: Since the plumule shows against gravity to form the shoot, it is said to have negative geotrophism.
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.
