Question

From the following sentences, find out incorrect sentence
A. The intercellular spaces are present in Parenchymatous tissues
B. At corners, Collenchymatous tissues are irregularly thickened
C. Examples of permanent tissues are Apical and intercalary meristems.
D. Meristematic tissues lack vacuoles in its early stage.

Answer 1

Hint: Permanent tissues are those that have completed their growth and differentiation. It is usually incapable of meristematic activity. Parenchyma, sclerenchyma, and collenchyma are permanent tissues. They are made up of meristematic cells and lack the power to divide and differentiate. These are present below the epidermis of the plant in all mature plants.

Complete answer:
Meristematic tissues are not permanent tissues because permanent tissues do not divide after differentiation.
For example, permanent tissues are parenchyma, collenchyma, xylem, phloem, etc.
The Apical and intercalary meristems are said to be responsible for the vertical growth of the plant. In addition, they are the primary meristems.
These meristems are not permanent tissues. Parenchyma cells are thin-walled, loosely arranged and intercellular spaces are present among them.
Collenchyma has irregular cell walls due to the deposition of cellulose. Meristematic tissue lacks vacuole in its early stage.
So, the correct answer is “Option C”.

Additional Information:
Based on location, meristems are classified as
-Apical (present at root and shoot tips)
-Lateral (present in the vascular and cork cambia)
-Intercalary (present at internodes)
The apical meristem is responsible for the extension of the roots and shoots.
Intercalary meristems have the power of cell division and allow the rapid growth and regrowth of many monocots.
Lateral meristem is responsible for the lateral growth of the plant.

Note:
Permanent tissues are those that have completed their growth and differentiation. It is usually incapable of meristematic activity. Meristematic tissues are not permanent tissues because permanent tissues do not divide after differentiation. The apical meristem is responsible for the extension of the roots and shoots. Intercalary meristems have the power of cell division and allow the rapid growth and regrowth of many monocots.
