Question

Name a region where apical meristem occurs.

Answer 1

Hint: Meristematic tissues are made up of smaller, undifferentiated, and actively dividing cells. They are present in specific parts of the plant body and broadly classified into two main types- Primary and Secondary meristems. The apical meristem falls under the category of Primary meristem. The word “apical” means ‘tip’.

Complete answer:
Apical meristem is chiefly found in three main regions:
Root apical meristem
Shoot apical meristem
Intercalary meristem
Root apical meristem which is often referred to as RAM means the root tip region.
Similarly, shoot apical meristem (SAM) means the growing tip of the shoot.
The apical meristems produce the primary tissues of the plant body and are responsible for primary growth.
While a stem is elongating, some meristematic cells are left behind from the same region. Then they get modified and form the axillary bud. Such types of buds are present in the axil of the leaves and are capable of forming a branch or a flower.
The meristematic tissues that occur in between the mature or permanent tissues is known as intercalary meristem. They are common in grasses where they regenerate the lost parts that are eaten up by grazing herbivores.

Note:
Another type of meristem, secondary meristem, is a product of dedifferentiation of the mature tissues. The intrafascicular cambium is a primary meristem in origin, but the interfascicular cambium is a secondary in nature.
The apical meristem produces dermal tissues, ground tissues, and vascular tissues in the plant.
