In plants, which of the following cells are living

Options

A. Xylem vessels
B. Meristem
C. Cork
D. Fibres

Answer

To answer the question "In plants, which of the following cells are living?" we will analyze each option provided: xylem, vessel, meristem, cork, and fiber.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are xylem, vessel, meristem, cork, and fiber.

2. **Analyze Each Option**:
- **Xylem**: Xylem is a type of vascular tissue responsible for the transport of water and nutrients. It is primarily composed of dead cells, which form hollow tubes to facilitate water conduction. Therefore, xylem cells are not living.

- **Vessel**: The term "vessel" typically refers to xylem vessels, which are also made up of dead cells. These cells have lignin deposits that provide structural support but do not contribute to living functions. Thus, vessels are not living cells.

- **Meristem**: Meristematic tissues are regions in plants where cells are actively dividing. These cells are living and have the ability to differentiate into various types of cells. Meristems are found at the tips of roots and shoots, and they are responsible for the growth of the plant. Therefore, meristem cells are living.

- **Cork**: Cork, also known as phellem, is a protective tissue found in the bark of trees. It is composed of dead cells that provide insulation and protection. Hence, cork cells are not living.

- **Fiber**: Fibers are made up of sclerenchyma, a type of tissue that consists of dead cells. These cells provide strength and support to the plant. Thus, fibers are also not living.

3. **Conclusion**: After analyzing all the options, the only living cells in the list are the **meristem cells**.

### Final Answer:
The living cells in plants from the given options are **meristem**.
