Consider the given two statements:
| Assertion (A): | Vessels are particularly advantageous in environments where rapid water transport is needed, such as in tall trees or in plants growing in warm, sunny environments. |
| Reason (R): | Tracheids are less efficient in conducting water due to their smaller diameter and the absence of large openings (perforations) at their ends. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
| 3. | (A) is True, (R) is False |
| 4. | (A) is False, (R) is True |

What are the distinctive features of collenchyma cells?
| 1. | They are elongated cells with thickened lignified cell walls. |
| 2. | They are dead cells that provide structural support. |
| 3. | They are elongated cells with unevenly thickened non-lignified cell walls. |
| 4. | They contain chloroplasts and primarily function in storage. |
