Where does mitosis occur in the bodies of vascular plants?
Solution
Ans.
The following cells/ tissue in the vascular plants show mitotic events-
I. Meristem tissues: Apical meristems (primary meristem) of shoot and root is under constant
mitotic divisions. Mitosis in these regions is the primary factor responsible for primary growth
(longitudinal, increase in height). Secondary meristems divide mitotically and responsible for
lateral growth (increase in thickness).
II. Parenchyma cell (ex- xylem and phloem parenchyma) constituting the parenchymatous tissue
show totipotency i.e. under appropriate conditions, these calls can dedifferentiate into embryonic
cells and form the entire plant through mitoses. These cells also may also divide to form new
cells meant for tissue repair..
