EMBRYO SAC

The embryo sac, also known as the female gametophyte, is an oval structure found in flowering plants’ ovules. When the haploid megaspore nucleus splits, an embryo sac is said to develop. It has two haploid nuclei and six haploid cells that are devoid of cell walls. The haploid nuclei can sometimes merge to create a […]

Embryo Development

Many changes occur throughout the embryonic stage, and each one is significant in its way. First and foremost, the cells of the embryo (known as embryonic stem cells) multiply and progress in their development. They develop into the hundreds of different types of cells that are required to construct a complete human body. The primary

Development of female gametophyte and megasporogenesis

Megasporophyll is the term used to describe the carpels of an angiosperm. It is subdivided into three regions: the ovary, the style, and the stigma. The ovary includes ovules, which are also known as megasporangium. It is the process of forming megaspores from the mother cell of a megaspore that is known as megasporogenesis (MMC).

Development of Embryo

Introduction An embryo is one of the initial stages of development of a multicellular organism. In general, in organisms that reproduce, embryonic development is a part of the life cycle that begins simply after fertilization. It continues through the formation of body structures, like tissues and organs. Every embryo starts development as a zygote, one

Creation of Spermatids

Spermatogenesis begins after puberty and continues into adulthood. The rate of spermatogenesis slows when testosterone release reduces with age. Male menopause, on the other hand, does not exist. Period. Seasonally breeding animals, such as bats and otters, have a testicular cycle in which the testes and spermatogenous tissue only operate during the breeding season. During

CONTRA DECIDUATE

Contra-deciduate placenta is a slightly modified kind of deciduate placenta seen in Parameles & Talpa (mole). Not only does this result in the loss of maternal tissue, but it also results in the loss of fetal tissue. Both the fetal and maternal portions of the placenta are absorbed in situ by the mother’s leucocytes. The

COMPONENTS OF REPRODUCTIVE HEALTH

The female reproductive system is complex that necessitates specific attention and safeguarding from sickness and injury. The labia, clitoris, vagina, ovaries, uterus & fallopian tubes are all part of it.  The reproductive health of a woman is determined not only by her physical health as well as by her mental health. It’s not just about being
