Ramet is

Options

A. clone
B. callus
C. cell aggregate
D. individual member of clone

Answer

To answer the question "Ramet is:", we will analyze the options provided and determine the correct definition step by step.

### Step-by-Step Solution:

1. **Understanding the Term "Clone":**
- A clone refers to offspring that are genetically identical to the parent. Clones arise from a single cell of the parent organism. Therefore, they share the same genetic material.

**Hint:** Think about how clones are formed and what they represent in terms of genetics.

2. **Defining "Callus":**
- A callus is an undifferentiated mass of cells. It typically refers to a mass of cells that have not yet specialized into different cell types. This term is often used in plant tissue culture.

**Hint:** Remember that callus refers to a mass of cells that are not yet specialized.

3. **Understanding "Cell Aggregate":**
- A cell aggregate refers to a loose collection of cells that are not tightly bound together. This term describes how cells can exist in a group without forming a structured tissue.

**Hint:** Consider how cells can group together without forming a cohesive structure.

4. **Defining "Individual Member of a Clone":**
- The term "ramet" specifically refers to an individual member of a clone. In a clonal population, each ramet is a genetically identical individual that arises from the same parent organism.

**Hint:** Focus on the relationship between ramets and clones.

5. **Conclusion:**
- Based on the definitions and understanding of the terms, the correct answer to the question "Ramet is:" is that a ramet is an individual member of a clone.

### Final Answer:
**Ramet is an individual member of a clone.**
