Question 1

A tissue is a group of cells having a common origin and usually performing a common function. A plant has two major groups of tissues based on the ability to divide:

Accepted Answer

Plants have two major groups of tissues based on their capacity to divide: Meristematic tissues and Permanent tissues. Meristematic tissues are capable of active cell division, leading to growth, while permanent tissues are derived from meristematic tissues and have lost the capacity to divide.

Question 2

Which of the following meristems is responsible for producing the primary plant body?

Accepted Answer

Apical meristems and intercalary meristems occur at the tips of roots and stems and in the grass respectively, and they contribute to the primary plant body by increasing the length of the plant.

Question 3

Intercalary meristem is placed between permanent tissues and is commonly found in:

Accepted Answer

Intercalary meristem occurs between permanent tissues and is typically found in grasses at the nodes or leaf bases, helping to regenerate parts removed by grazing herbivores.

Question 4

Which of the following is an example of lateral meristem in plants?

Accepted Answer

Fascicular cambium, interfascicular cambium, and cork cambium are examples of lateral meristems that are responsible for producing the secondary plant body (increasing girth).

Question 5

Permanent tissues having all cells similar in structure and function are called:

Accepted Answer

Simple permanent tissues consist of cells that are structurally and functionally similar, such as parenchyma, collenchyma, and sclerenchyma.
