Question

Growth of cell wall during cell elongation takes place by
a. Apposition
b. Intussusception
c. Both A and B
d. Super position

Answer 1

The progressive process that is controlled by elements like light and phytohormones is called the process of cell elongation. We can say that it has great importance for the growth of a plant. In general, malfunctioning of mutants in their retort to light and numerous hormones are habitual dwarfs.

Complete answer:
- A wall of the cellulosic cell generally covers the sections of the plant. We can tell that the walls of these cells are precisely dead when they become nature. However, these cell walls grow when they are immature to permit cell elongation.
- One can define the term Intussusception as the development by the deposition of novel resources amid existing elements of cell walls. Thus, we can conclude that the process of cell elongation occurs through the procedure of Intussusception.
- However, in the procedure of Apposition, many new wall layers are formed. Growth of the wall in new cells occurs through Apposition. Thus, the development of the wall in new cells occurs through Apposition.
- Besides, the superposition is the action of inserting one thing on or above the other, particularly in an intention towards them to coincide.

Hence, the correct answer is option (B).

Note: In the duration of the cell elongation, the cells develop. However, we need to note that the process of Intussusception is involved only in the procedure of cell elongation of the plants. However, they do not get involved in the process of the growth of cells. The method of Apposition is the one that gets involved when the cells need to grow.
