Question

Find out incorrect sentence:

• A. Parenchymatous tissues have intercellular spaces.
• B. Collenchymatous tissues are irregularly thickened in corners
• C. Apical and intercalary meristems are permanent tissues
• D. Meristematic tissues, in their early stage, lack vacuoles

Answer 1

The correct option is C

Apical and intercalary meristems are permanent tissues

The correct option is A and C.
Explanation for the correct options:

Option A:

1. A simple permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached.
2. They are non-vascular and made up of undifferentiated, primitive living cells that have undergone modifications to carry out distinct tasks. These cells are closely packed cells.

Option C:

1. Plants' root and shoot tips have an area of cells called the apical meristem that can divide and grow.
2. The name "intercalary meristem" refers to a form of meristematic tissue that is connected to length growth in the midway position.
3. Although they differentiate to produce many kinds of permanent tissues, apical and intercalary meristems are not permanent tissues.
4. Meristematic tissues are made up of a variety of shaped live cells.
5. They have a large nucleus without a vacuole.
6. There is no intercellular gap in the cells.
7. The meristem is the region in which these cells are found.
8. The intercalary meristem eventually has limits; it will eventually reach a limit and mature into permanent tissues, unlike the other basic meristematic tissues.

Explanations for the incorrect options:
Option B:

1. In the stems of immature plants, collenchymatous tissue serves as a supporting tissue.
2. It gives the plant body mechanical support, elasticity, and tensile strength.
3. It facilitates the production of sugar and its storage as starch.
4. It can withstand the shredding force of the wind and is found on the border of leaves.
5. Collenchymatous tissues, which are mechanical in plants, are distinguished by cellulose deposition at the cell corners, which results in localized thickenings of the cell wall.

Option D:

1. Meristematic tissues, also known as meristems, are tissues in which the cells are always young and actively divide throughout the plant's existence.
2. The new cell that stays in the meristem when a meristematic cell divides into two is known as the original, while the other is known as the derivative.
3. Meristematic cells lack a vacuole but contain a large nucleus and a thick cytoplasm.

Final answer: Apical and intercalary meristems are permanent tissues and Parenchymatous tissues have intercellular spaces are incorrect statements.
