Mesophyll cells present in the ground tissue of leaves are:
1. chloroplasts lacking thin walled cells
2. chloroplasts containing thick walled cells
3. chloroplasts containing thin walled cells
4. chloroplasts lacking thick walled cells
Open vascular bundles:
I: | have cambium present between xylem and phloem |
II: | possess the ability to form secondary tissues |
III: | are rare in dicotyledonous stems |
1. Only I and II are correct
2. Only I and III are correct
3. Only II and III are correct
4. I, II and III are correct
1. | Metaxylem | 2. | Cambium |
3. | Protoxylem lacuna | 4. | Metaphloem |
The type of vascular bundles shown in the given figure would most likely be seen in:
1. | Dicotyledonous stem | 2. | Roots |
3. | Monocotyledonous stem | 4. | Leaves |
In conjoint type of vascular bundles:
I: | xylem and phloem are jointly situated on the same radius of vascular bundles. |
II: | xylem is usually located on the outer side of the phloem. |
1. Only I is correct | 2. Only II is correct |
3. Both are correct | 4. Both are incorrect |
