Intercalary meristems are derived from
Intercalary meristems are derived from
The correct option is A Primary meristem
The correct option is A.
Explanation of the correct option: -
- Meristematic gets its name from the Greek word meristos, which means “divided.”
- Meristematic tissues are made up of young, densely packed live cells that divide and add new ones.
- Plant development and growth are controlled by meristematic tissues.
- They can be found in plant parts such as root tips, branches, and shoots. They are tissues with a thin wall.
- The nucleus is present, but the vacuoles are either nonexistent or in limited numbers.
- The intercalary meristem is a meristematic tissue found at the base of leaves and internodes.
- The intercalary meristem is responsible for increasing the length of organs and branches, as well as the bending movement of twins.
- Intercalary meristem is a derivation of primary meristem because they both aid in growth.
Explanation of the incorrect options: -
Option B: - A secondary meristem is a form of meristematic tissue in plants that is responsible for secondary development, such as girth or thickness growth. It is in opposition to the primary meristem, which is engaged in primary growth, such as height or length gain.
Option C: - Meristem (such as the cambium and cork cambium) that runs parallel to the sides of an organ and is responsible for the organ's increased diameter.
Option D: - The part of a primary meristem that contains actively dividing, undifferentiated, isodiametric thin-walled cells, as well as their most recent descendants.
Final Answer: - Intercalary meristems are derived from primary meristems.
