Assertion (A): Grasses get regenerated even after grazed by herbivores Reason (R): In grasses meristems are present in between mature tissues, Options:
1 (A) and (R) are true and (R) is the correct explanation of \((\mathrm{A})\).
2 (A) and (R) are true but (R) is not the correct explanation of \((\mathrm{A})\).
3 (A) is true but (R) is false.
4 (A) is false but (R) is true.
Explanation:
: The grass stem regenerates after grazing due to intercalary meristem because this helps in regeneration of stem in grasses removed by grazing herbivores.

Which one of the following is not a lateral meristem ?
1 Vascular cambium
2 Interfascicular cambium
3 Phellogen
4 Intercalary meristem
Explanation:
Exp:D Fascicular vascular cambium, interfascicular cambium and cork-cambium (phellogen) are examples of secondary or lateral meristem. These are responsible for producing the secondary tissues. Apical and intercalary meristems are primary meristems. They are located at the base of internodes and promotes lengthening of stem and increase height of plant. Vascular cambium- when the cells of cambium present between two vascular bundles. Intrafascicular cambium- when the cells of cambium present between primary xylem and primary phloem. Phellogen- Phellogen is a couple of layers thick.

Axillary buds which forms branches or flowers are present in
1 Lateral meristem
2 Apical meristem
3 Cylindrical meristem
4 Intercalary meristem
Explanation:
Exp:B Axillary buds which forms branches or flowers are present in 'Apical meristem'. Apical meristem refers to the meristem that occurs at the tips of roots, stems and branches, which bring about the primary growth of the plants. Thus, Axillary buds and terminal bud both are derived from the activity of apical meristem.

Which of the following statements about cork cambium is incorrect?
1 It is a couple of layers thick
2 It forms secondary cortex on its outerside
3 It forms a part of periderm
4 It is responsible for the formation of lenticels
Explanation:
Exp:B Cork cambium is a meristematic tissue involved in secondary growth. It is also called phellogen. It develops in the cortex region. It is few layers thick and it cut off cells into outer layer and inner layer the former differentiates into cork (phellem) while latter differentiate into secondary cortex (phelloderm) All these three layers phellogen, phellem and phelloderm are collectively called as periderm. In woody trees, the phellogen cut off closely arranged parenchymatous cells, rupturing the epidermal cell to form lenticles. Pericycle also becomes meristematic to form cork cambium.

Axillary bud and terminal bud are derived from the activity of : -
1 Lateral meristem
2 Intercalary meristem
3 Apical meristem
4 Parenchyma
Explanation:
Exp:C Meristem is the group of actively dividing cells that give rise to the side to the new cells after division. Apical meristems are situated at the tip of root and shoot of the plants. They take place initial growth. Plants elongate and increase in light as a result of division in the meristem.
