Tissues Test - 12

• The dividing tissue in plants is known as Meristematic tissue.

• Meristematic cells give rise to various organs of a plant and are responsible for growth.

• It contains undifferentiated cells.

• They are commonly known as meristems.

• On the basis of where they are present i.e. their position, the Meristematic tissues are classified into three types:

o Apical Meristem (At the tips)

o Intercalary Meristem (In the middle)

o Lateral Meristem (At the sides)

• Meristem tissues do not have any waste material to store so vacuoles are usually absent in the meristematic cells.

• Vacuole is a cell organelle used to store waste materials, store nutrients, excess salts etc. and usually big and more in number in mature cells. Meristematic cells are mainly concerned with cell division.

• Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and thin cell wall. Vacuoles causes hindrance in cell division as it is full of cell sap to provide turgidity and rigidity to the cell.

• Meristematic cells divide frequently and give rise to new cells and hence they need dense cytoplasm and thin cell wall.

• They also lack vacuoles or have small vacuoles, and no intercellular spaces.

Simple permanent tissues are classified into three main types. They are parenchyma, collenchyma, and sclerenchyma. 

Hence, option D is correct.

Phloem conducts foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.

Hence, option B is correct.

Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally.

Hence, option A is correct.
