Which one is the reproductive unit having an embryo, reserve food and protective covering ?

Options

A. Spore
B. Fruit
C. Seed
D. Fruitlet.

Answer

To solve the question "Which one is the reproductive unit having an embryo, reserve food, and protective covering?", we can analyze the options provided:

### Step 1: Understand the Options
1. **Spore**: A spore is a unit of asexual or sexual reproduction in certain organisms, but it does not have an embryo, reserve food, or protective covering in the same way seeds do.

2. **Fruit**: A fruit is the mature ovary of a flower, which contains seeds. While fruits do protect seeds, they are not the reproductive unit themselves; rather, they are structures that develop from flowers.

3. **Seed**: A seed is a ripened ovule that contains an embryo, has stored reserve food for the embryo, and is encased in a protective covering (the seed coat). This fits the description given in the question.

4. **Fruitlet**: A fruitlet is an immature or small fruit, which again does not fit the description of a reproductive unit with an embryo, reserve food, and protective covering.

### Step 2: Identify the Correct Answer
Based on the analysis:
- The only option that contains an embryo, reserve food, and protective covering is **Seed**.

### Conclusion
The correct answer is **C. Seed**.
