All the cells of young embryo are:

Options

A. cork cells
B. collenchymatous
C. meristematic
D. sclerenchymatous

Answer

To answer the question "All the cells of a young embryo are:", we will analyze the types of cells present in a young embryo and identify the correct type.

### Step-by-Step Solution:

1. **Understanding the Young Embryo**: A young embryo is in the early stages of development. During this phase, the cells are actively dividing and differentiating to form various tissues and organs.

2. **Identifying Cell Types**:
- **Cork Cells**: These are dead cells that provide support and protection. They are not found in young embryos but rather in mature structures.
- **Collenchyma Cells**: These are living cells that provide support and are involved in the process of photosynthesis. However, they are not the primary type of cells in a young embryo.
- **Meristematic Cells**: These are the key cells in a young embryo. They are actively dividing cells that contribute to growth and the formation of new tissues. Meristematic tissue is responsible for the continuous growth of the plant.

3. **Conclusion**: Based on the analysis, the correct answer to the question is that all the cells of a young embryo are **meristematic cells**.

### Final Answer:
All the cells of a young embryo are **meristematic cells**.
