The seed in which reserve food is present in the perisperm

Options

A. Nymphaea
B. Coconut
C. Onion
D. Litchi

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Structure**: Seeds are the result of fertilization in angiosperms and typically contain stored food to support the embryo during germination. The main forms of stored food in seeds are cotyledons and endosperm.

2. **Identifying Perisperm**: Perisperm is a specific type of seed structure that is derived from the nucellus, which is part of the ovule. It serves as a food reserve for the developing embryo.

3. **Recognizing Perispermic Seeds**: Seeds that contain their food reserves in the form of perisperm are known as perispermic seeds. This is distinct from seeds that have endosperm or cotyledons as their food storage.

4. **Examples of Perispermic Seeds**: Common examples of seeds that have perisperm include:
- Beet (Beta vulgaris)
- Black pepper (Piper nigrum)
- Nymphaea (water lily)

5. **Conclusion**: Based on the information provided, the correct answer to the question is that the seed in which reserve food is present in the perisperm is called "perispermic seeds." Among the options given, Nymphaea is one of the examples of such seeds.

**Final Answer**: The seed in which reserve food is present in the perisperm is called a "perispermic seed," with Nymphaea being an example.
