Gemmae are

Options

A. non green, multicellular, asexual buds
B. green,multicellular, asexual buds
C. non green, unicellular, asexual buds
D. non green, multicellular, sexual buds

Answer

**Step-by-Step Solution:**

1. **Understanding Gemmae**: Gemmae are asexual reproductive structures found in certain plants, particularly in liverworts and some mosses. They are small, multicellular, and can develop into new individuals.

2. **Formation of Gemmae**: Gemmae are produced in a cup-like structure known as the gemma cup, which is located on the thallus (the body of the plant). This structure aids in the asexual reproduction process.

3. **Characteristics of Gemmae**:
- They are typically haploid, meaning they contain a single set of chromosomes.
- They are capable of developing directly into a new organism when they come into contact with suitable soil conditions.

4. **Examples of Plants with Gemmae**: Gemmae are commonly found in plants like Marchantia (a type of liverwort) and various moss species.

5. **Analyzing the Options**: In the question, we need to determine the correct definition of gemmae from the provided options:
- The first option describes them as non-green multicellular asexual buds, which is incorrect.
- The second option describes them as green multicellular asexual buds, which is correct since gemmae are indeed green and multicellular.

6. **Conclusion**: The correct option regarding gemmae is that they are green multicellular asexual buds that can give rise to new plants.
