Question 26

In dicot root pericycle has

Answer 26

Thicked wall parenchymatous cell and pericycle undergoes dedefferentiation and form cambium and lateral root

Monot root do not undergoes

Answer 30

Secondary growth

Question 31

Some tissue inthe inner side of endodermis such as pericycle pith vascular bundle constitue stele

Answer 31

Wrong all tissue not some tissue
