In the given diagram, the root apical meristem is represented by the letter:
1. A |
Match the parts labeled as A, B and C in the diagram of stem apex with their derivatives in the plant body:
A | B | C | |
1. | Dermatogen | Periblem | Plerome |
2. | Dermatogen | Plerome | Periblem |
3. | Epidermis | Vascular bundle | Cortex |
4. | Epidermis | Cortex | Vascular bundle |
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 |
The apical meristems in the plants:
1. | occur at the tips of both roots and shoots and produce primary tissues |
2. | occur at the tip of root and base of the stem and produce secondary tissues |
3. | occur at the base of root and tip of the stem and produce primary tissues |
4. | occur at the tips of both roots and shoots and produce secondary tissues |
All the following are examples of secondary or lateral meristems except:
1. | Fascicular vascular cambium | 2. | Intercalary meristem |
3. | Interfascicular meristem | 4. | Cork cambium |
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. |
In the given diagram, the axillary bud is represented by the letter:
1. A 2. B 3. C 4. D |
A simple plant tissue is characterized by:
1. continued cell division
2. presence of only living cells
3. cells with chloroplasts
4. presence of only one type of cells
All the following regarding parenchyma tissue in plants are correct except:
1. Cells are generally isodiametric
2. Cell walls are generally thick
3. Cell walls are made of cellulose
4. They perform photosynthesis, storage and secretion
