Identify the tissue system from among the following:
1. Parenchyma | 2. Xylem |
3. Epidermis | 4. Phloem |
Regarding the epidermal tissue system of angiosperms:
I: | Cuticle is absent in roots |
II: | Guard cells are dumb-bell shaped in grasses and possess chloroplasts |
III: | Root hairs are multicellular and the stem hairs are unicellular |
1. Only I is correct
2. Only I and II are correct
3. Only II is correct
4. Only II and III are correct
What would be true for A and B shown in the given diagram?
1. | A shows open stomatal aperture while B shows closed stomatal aperture |
2. | A shows closed stomatal aperture while B shows open stomatal aperture |
3. | A shows the stomata in grasses |
4. | B shows the stomata in grasses |
The incorrect statement regarding epidermal tissue system in angiosperms would be:
1. It comprises of epidermal cells and stomata but not the appendages such as trichomes
2. It is the outermost layer of the primary plant body forming a continuous layer
3. It is usually single layered
4. Cells are parenchymatous with a large vacuole
