Question

4-celled mature embryosac is
found in-​

Answer 1

Answer:

The embryo sac development follows the Polygonum type (Panchakshrappa, 1966). The ovules are anatropous, bitegmic, and crassinucellate and are borne on an axil placentation. The inner integument forms the micropyle. In the ovular primordium, the hypodermal archesporial cell cuts off a primary parietal cell and a primary sporogenous cell. The former undergoes anticlinal division. The sporogenus cell enlarges into a megaspore mother cell, which undergoes meiosis forming megaspores.
