The given figure represent a stage of embryonic development. Identify the stage with its feature.
1 Blastocysts, ready to fertilize with sperm.
2 Secondary oocyte, implants on endometrial layer of uterus.
3 Morula, formed by mitotic division of zygote.
4 Ovary, produce female gamete and secretes hormones like estrogen etc
Explanation:
(c) The given figure shows the morula stage of embryonic development. Morula is produced by a series of cleavage (mitotic) divisions of the early embryo, starting with the single-celled. Once the embryo has divided into 16 cells, it begins to resemble a mulbery, hence the name.
