Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Increase in girth of the plant as a result of the activities of primary and secondary lateral meristem is called
A
Primary growth
B
Lateral growth
C
Secondary growth
D
Intercalary growth
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘secondary growth’

Detailed explanation-2: -Lateral meristems assist in increasing girth. These lateral meristems assist in the lateral growth of the plant, the growth in the thickness.

Detailed explanation-3: -Secondary growth is characterized by an increase in thickness or girth of the plant, and is caused by cell division in the lateral meristem. Figure 1 shows the areas of primary and secondary growth in a plant.

Detailed explanation-4: -Secondary growth is an increase in thickness or girth of the plant body due to activity of lateral meristems. Lateral meristems are located laterally around the stem (not at the tips like apical meristems).

Detailed explanation-5: -The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant. It is caused by cell division in the lateral meristem.
