Statement I: | Fascicular vascular cambium, interfascicular cambium, and cork-cambium are examples of lateral meristems. |
Statement II: | These are responsible for producing secondary tissues. |
Assertion(A): | Apical meristems and intercalary meristems are primary meristems. |
Reason (R): | They appear early in life of a plant and contribute to the formation of the primary plant body. |
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. | Both (A) and (R) are False |
The meristem that helps grasses regenerate parts removed by the grazing herbivores is the:
1. | Shoot apical meristem | 2. | Root apical meristem |
3. | Intercalary meristem | 4. | Lateral meristem |
I: | is constituted by some cells ‘left behind’ from shoot apical meristem during the formation of leaves and elongation of stems. |
II: | is present in the axils of leaves and is capable of forming a branch or a flower. |
All the following are true for trichomes except:
1. | they are usually unicellular |
2. | they may be branched |
3. | they may be secretory |
4. | they help in prevention of water loss due to transpiration |
