The organizatin of shoot apex into tunic...

The organizatin of shoot apex into tunica and corpus is determined largely on the basis of
(a) Regions of meristematic activity
(b) Planes of cell division
(c) Rate of shoot tip growth
(d) Rate of cell division

A

planes of cell division

B

regions of meristematic activity

C

rate of cell growth

D

rate of shoot tip growth

Text Solution

Verified by Experts

The correct Answer is:
a
Tunica (outer zone of shoot apex) forms protoderm which through anticlinal divisions gives rise to epidermis of stem and leaves . Corpus is inner mass of meristem where cells undergo divisions in different planes to form procambium and ground meristem.
