NEET BIOLOGY

Detailed explanation-1: -Solution : Intercalary meristems are intercalated in between the permanent tissues. They may be present either at the base of the internode as in the stems of various grasses and wheat, or at the base of the leaf as in Pinus, or at the base of a node as in mint (Mentha viridis).

Detailed explanation-2: -Assertion : In grasses and cereals, intercalary meristems are not present. Reason : Intercalary meristems form permanent tissues.

Detailed explanation-3: -The apical meristem is located at the tips of roots and shoots. The intercalary meristem is present at internodes. They are primary meristems and are not permanent tissues. They are present during the initial growth phase of the plants and help form the primary plant body.

Detailed explanation-4: -Both apical meristem and intercalary meristem are ‘primary’ meristems as they appear early in the life of a plant and helps in the formation of the primary plant body. So, the correct answer is ‘primary’.

Detailed explanation-5: -Answer: Intercalary meristems is located in the leaves and internodes at the intercalary position. These help to increase the length of the internode. It is found in grass, monocots, and pines.
