A student while observing an embryo of a gram seed listed various parts of the embryo as listed below: Testa, Micropyle, Cotyledon, Tegmen, Plumule, Radicle.
On examining the list the teacher commented that only three parts are correct. Select these three correct parts:

Options

A. Cotyledon, Testa, Plumule
B. Cotyledon, Plumule, Radicle
C. Cotyledon, Tegmen, Radicle
D. Cotyledon, Micropyle, Plumule

Explanation

To solve the question regarding the parts of the embryo of a gram seed, we need to identify which three parts from the given list are correct. Let's analyze the parts mentioned:

1. **Testa**: This is the outer seed coat that protects the seed. However, it is not a part of the embryo itself.
2. **Micropyle**: This is a small opening in the seed coat, but it is not part of the embryo.
3. **Cotyledon**: This is a part of the embryo that serves as a food storage area and is present in dicot seeds like the gram seed. This is correct.
4. **Tegmen**: This is the inner layer of the seed coat, similar to the testa, and is not part of the embryo.
5. **Plumule**: This is the part of the embryo that develops into the shoot or stem of the plant. This is correct.
6. **Radicle**: This is the part of the embryo that develops into the root. This is correct.

From the analysis, the three correct parts of the embryo of a gram seed are:
- Cotyledon
- Plumule
- Radicle

Thus, the correct answer is that the three parts of the embryo are Cotyledon, Plumule, and Radicle.
