DENDROLOGY

Detailed explanation-1: -Plumule is the part of the embryo which emerges from the seed and develops into the shoot of the plant. It further develops organs such as the stem, flowers, fruits and seeds. Since the plumule forms the shoot of the plant, it is responsible for performing photosynthesis.

Detailed explanation-2: -Plumule: Plumule is the embryonic shoot that gives rise to the shoot system. It is covered by a protective sheath called coleoptile. Plumule emerges only after the radicle. It is negatively geotropic and positively phototropic.

Detailed explanation-3: -The growing tip of the tiny shoot called epicotyl is the part that is known as the plumule. Epicotyl develops into leaves, stems, and flowers as the plant grows. The process of germination of the seed can be classified into two parts: epigeal germination and hypogeal germination.
