The embryo sac is ______
The method of embryo sac forming from a single megaspore is called ______.
In a flower, if the megaspore mother cell forms megaspores without undergoing meiosis and if one of the megaspores develops into an embryo sac, its nuclei would be ______.
Draw the diagram of a mature embryo sac and show its 8-nucleate, 7-celled nature. Show the following parts: antipodals, synergids, egg, central cell, polar nuclei.
With a neat, labelled diagram, describe the parts of a mature angiosperm embryo sac. Mention the role of synergids.
Trace the development of a megaspore mother cell to the formation of a mature embryo sac in a flowering plant.
Explain the monosporic development of the embryo sac in the ovule of an angiosperm.
Draw a diagram of the mature embryo sac of an angiospermic ovule and label any four parts in it.
The female gametophyte of angiosperms is called the embryo sac. How many cells and nuclei does a mature embryo sac contain?
During the development of the female gametophyte, the functional megaspore undergoes mitotic divisions without immediate cell wall formation. What are these divisions called?
In the first mitotic division of the functional megaspore, the two daughter nuclei move to opposite poles of the enlarging megaspore. What stage is this called?
Which cells are located at the chalazal end of the mature embryo sac, and how many of them are present?
How many nuclei contribute to the formation of the endosperm, and what is the resulting ploidy level of the endosperm?
Considering the cell distribution in a mature embryo sac, how many haploid cells are present in total?
The mature embryo sac is described as monosporic and of the Polygonum type. What does the term monosporic indicate about the origin of the embryo sac?
What is the total number of haploid nuclei present in the 8-nucleate stage of the developing female gametophyte before cell walls are formed?
During the development of the embryo sac, which stage immediately precedes the formation of the polar nuclei by migration?
