Read following four statement (a-d) and select correct statements:- (a) Embryonic meristem is an example of primary meristem (b) Apical meristems are responsible for primary growth (c) Intercalary meristem occurs between mature tissue (d) Fascicular vascular cambium is an example of lateral meristem

Assertion : Primary growth of the plants contributes to the elongation of the plants along their axis. Reason : Root apical meristem and shoot apical meristem are responsible for primary growth of the plants.

Chromosome number in endosperm cell of plant a and in the root apical meristem cell of plant b together equal to chromosome number in shoot apical meristem cell of apple. Plants a and b respectively are

(a) Leaf develops at the node and bears a bud in its axis (b) Axillary bud may develop into a branch (c) Leaves originate from shoot apical meristems and are arranged in basipetal manner. How many statements are correct?

Identify the two correct statements from the following : (i) Apiculture means apical meristem culture. (ii) Spinach is iron-enriched. (iii) Green revolution has resulted in improved pulse-yields. (iv) Aphids cannot infest rapeseed mustard.

How many of the given statements are correct w.r.t meristmatic tissues? A. The meristems which occur at the tips of roots and shoots are primary meristems. B. Some cells 'left behind ' from the shoot apical meristem constitutes the accessory bud. C. Cork cambium is responsible for producing secondary tissues. D. The process of formation of structurally and functionally specialised cells is known as dedifferentiation. E. The intercalary meristem occurs in grasses and regenerates parts removed by grazing herbivore. F. Interfascicular cambium and fascicular vascular cambium are absent in woody plant axis.

Read-the following statements carefully and give the answer? A) A leaf is a lateral, generally flattened structure borne on the stem B) The axillary bud later may develop into a branch or flower C) Leaves originate from shoot apical meristem D) Stem perform the functions of storage, support, protection and vegetative reproduction How Many of them are correct

Read the following three statements (A-C) and select the option which includes all the correct ones only: i. During the primary growth of the plant, specific regions of the apical meristem produce dermal tissue, ground tissue and vascular tissue. ii. In plants, growth is restricted to specialized regions of active cell division iii. Secondary meristems are also known as cylindrical meristems.

These are cylindrical meristems

Why apical intercalary meristems are called primary meristems?
