Question

Intercalary meristem produces
a. Secondary growth
b. Primary growth
c. Apical growth
d. Secondary thickening

Answer 1

Intercalary meristems are suitable for cell division. They consider quick development, advancement, and regrowth of numerous monocots. Intercalary meristems at the hubs of bamboo take into account quick stem extension, while those at the base of most grass leaf-cutting edges permit harmed leaves to quickly regrow.

Complete answer:
- Intercalary meristem is a sort of meristematic tissue at the base of hubs and leaf-cutting edges of monocots. An intercalary meristem produces primary growth. Hence, option B is correct.
- Meristematic tissues comprise cells that are effectively separating. They are liable for the vague development in plants. They offer ascent to lasting plant tissues, for example, vascular tissues, epidermis, phellem, ground tissues, and so on. Given the area of the meristematic tissue.
- Apical meristem refers to the growth in the apical region mainly present in the upper portion of the stem. It comprises meristematic tissue. So, option C is incorrect.
- Secondary growth is referred to as the growth in the thickening of plants. This type of growth occurs due to the presence of cambium in plants. So, option A is incorrect.
- Secondary thickening in plants is due to the presence of cambium. This type of feature is found in dicotyledonous. So, option D is incorrect.
- Intercalary meristem is a kind of meristematic tissue related to the development long in the center position, in this way the name. Specifically, it consists of meristematic cells that partition mitotically in the stem at the base of hubs and leaf sharp edges. The development now is alluded to as intercalary development.

Hence, the correct answer is option (B).

Note: Intercalary meristem is generally present in advance plants. This sort of meristem happens just in monocots, especially grass. This is basic to these plant bunches as it fills in as a versatile system against herbivory. Through intercalary development, these plants can quickly regrow leaves and extend stems to make up for plant parts brushed by herbivores.
