Q. The type of tissue that is formed by the dedifferentiation of permanent tissue is known as

1. primary meristem
2. apical meristem
3. secondary meristem
4. lateral meristem

Q. Based on the function of the meristems, protoderm gives rise to

1. phloem
2. xylem
3. epidermal layer
4. cambium

Q. In stem, vascular cambium and cork cambium form secondary tissues respectively in which region:

2. Intrastelar region and extrastelar region
3. Both in stelar region
4. Both in cortical region

1. 2
2. 3
3. 4
4. 5

Q. Based on the type of functions performed, meristems are classified as
