What type of cell division takes place in the functional megaspore initially in angiosperms?
1 Homeotypic without cytokinesis
2 Reductional without cytokinesis
3 Somatic followed by cytokinesis
4 Meiotic followed by cytokinesis
Explanation:
In angiosperms, initially homeotypic mitotic division without cytokinesis takes place in the functional megaspore. This division in functional megaspore produces eight nuclei without cell wall formation. After that these nuclei undergo cell wall formation and form 7-celled, 8-nucleate structure which is called as embryo sac.
