The plane of division in tunica is

The tunica is:

Assertion: In planaria, the plane of division runs along the longitudinal axis of the individual. Reason: They are bilaterally symmetrical.

A flower which can be divided into equal vertical halves by more than one plane of division is

In Vorticella during binary fission plane of division passes along

In Vorticella during binary fission plane of division passes along

Organisation of stem apex into corpus and tunica is determined mainly by

The cells of corpus undergo divisions in various planes and result in the formation of

The fission in which plane of cytoplamic division coincides with the transverse axis of individual is called

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
