When new cells added to the plant body by the activity of meristems is called as
1 Random growth
2 Indirect growth
3 Closed growth
4 Open growth
Explanation:
When new cells are always added to the plant body by the activity of meristems is called as open growth.

Read the following statements carefully and select the incorrect statements.
1 Cells positioned away from root apical meristems differentiate as root-cap cells
2 During differentiation, cells undergo few to major structural changes in their cell walls and not in protoplasm.
3 The various anatomical features in plantsand the functions they perform are related.
4 Same meristem have different structures at maturity
Explanation:
During differentiation, cells undergo few to major structural changes both in their cell walls and protoplasm. For example, to form a tracheary element, the cells would lose their protoplasm. They also develop a very strong, elastic, lignocellulosic secondary cell walls, to carry water to long distances even under extreme tension.

Which of the following tissues in a woody dicotyledonous plant are the products of redifferentiation?
1 Secondary phloem
2 Secondary xylem
3 Cork
4 All of the above

Which type of growth is responsibility of meristems?
1 Plasmal growth
2 Primary growth
3 Secondary growth
4 Both (2) and (3)
Explanation:
Plant growth is unique because plants retain the capacity for unlimited growth throughout their life. This ability of the plants is due to the presence of meristems at certain locations in their body. The cells of such meristems have the capacity to divide and self-perpetuate. Meristem is responsible for both primary and secondary growth in plants.
