Correct option is B
The correct answer is (b) In a seed.
Plumule is found in a seed. It is a part of the seed embryo that develops into the shoot of a plant.
Explanation
- The plumule is located above the cotyledons in a seed.
- It is the growing tip of the shoot, called the epicotyl.
- The plumule is protected by the seed coat until the seed germinates.
- As the seed germinates, the plumule emerges from the soil and grows into the first leaves of the plant.
- The plumule grows towards sunlight, which is called positive phototropism.
- The plumule develops into the stem, leaves, flowers, and seeds of the plant.
