The following statements have been proposed for plant vegetative development:
P. Lateral roots develop from epidermal cells.
Q. Shoot axillary meristem develops from shoot apical meristem during differentiation of leaf primordia.
R. Root cap is made up of dead cells.
S. Lateral meristems and cylindrical meristems found in roots and shoots result in secondary growth.
Which of the above statements are true?
P and Q
Q and S
P, Q and S
R and S
Lateral roots are formed from the pericycle, which is a layer of cells located just inside the endodermis in the root. Therefore statement P is wrong.
The root cap is a specialised structure found at the tip of plant roots. Therefore statement R is also wrong.Hence, the correct answer is option 2.
