The only plant cells without nuclei among the following are
Or
The tissue which is living but does not posses nucleous in mature stage is
(a) Cambium
(b) Xylem vessels emements
(c) Root hairs
(d) Companion cells

Options

A. Cambium
B. Xylem vessels emements
C. Root hairs
D. Companion cells

Answer

To solve the question regarding which plant cells do not have nuclei, we can analyze each option provided:

1. **Understand the Question**: We are looking for plant cells that are living but do not possess a nucleus in their mature stage.

2. **Analyze Each Option**:
- **Option (a) Cambium**: Cambium is a type of meristematic tissue that is actively dividing and contains nuclei. Therefore, this option does not fit the criteria.
- **Option (b) Xylem vessel elements**: Xylem vessel elements are specialized cells that are involved in the conduction of water. In their mature form, they lose their nuclei and are considered living cells that function without a nucleus. This option fits the criteria.
- **Option (c) Root hairs**: Root hairs are extensions of root epidermal cells and are living cells that contain nuclei. Thus, this option does not fit the criteria.
- **Option (d) Companion cells**: Companion cells are associated with sieve tube elements in phloem and are living cells that contain nuclei. Therefore, this option does not fit the criteria.

3. **Conclusion**: Based on the analysis, the only plant cells that are living but do not possess nuclei in their mature stage are the **Xylem vessel elements**.

**Final Answer**: (b) Xylem vessel elements
