Answer 1

There is no distinction between tunica and corpus layers in the stem apices of
➡️ Some pteridophytes

Answer 2

Answer:

D) All angiosperms

Explanation:

The idea of tunica corpus, given via way of means of Schmidt (1927), is attached to the apical meristem of the shoot apex or stem. Similar to it, tunica is the hearthplace apex outer area at the same time as corpus is the internal area. Tunica bureaucracy a protoform which offers upward thrust to stern and leaves the dermis. Corpus is the internal mass this is divided to shape procambium and terrestrial meristem.

Tunica-Corpus Theory

This idea changed into given via way of means of Schmidt to explain the company in a shoot apex. According to this idea, the apical area of the shoot includes  zones:

Tunica – It is the outer enveloping layer, made from small cells that supply upward thrust to the dermis and outer cortex.

Corpus – It is the mass of cells forming the internal core. It produces the internal cortex, procambium and pith.

So, the answer is option D) All angiosperms
