What is microgametogenesis and megagametogenesis?

Megagametogenesis creates the female gametophyte, which is an integral part of pollination, a very prominent process in plants. The male counterpart to megagametogenesis is called microgametogenesis. Microgametogenesis is the process of the formation of the male gametophyte.

What is difference between Megasporogenesis and megagametogenesis?

In the megasporogenesis the diploid megaspore mother cell undergoes meiosis to form four haploid megaspores whereas in the megagametogenesis the megaspore develops into female gamete.

What is Megasporogenesis and pollination?

Megasporogenesis refers to the development of megaspores from the megasporocyte, the cell that undergoes meiosis. Meiosis of the megasporocyte nucleus results in the formation of four haploid megaspore nuclei. In most taxa, meiosis is followed by cytokinesis, resulting in four megaspore cells.

What are the types of Megasporogenesis?

Angiosperms exhibit three patterns of megasporogenesis: monosporic, bisporic, and tetrasporic, also known as the Polygonum type, the Alisma type, and the Drusa type, respectively.

What is Microgametogenesis in plants?

Microgametogenesis is the process in plant reproduction where a microgametophyte develops in a pollen grain to the three-celled stage of its development. In flowering plants it occurs with a microspore mother cell inside the anther of the plant.

What is the meaning of Microgametogenesis?

Microgametogenesis comprises events which lead to the progressive development of the unicellular microspores into mature microgametophytes containing the gametes. This phase begins with the expansion of the microspore which is commonly associated with the formation of a single large vacuole.

What is difference between Microsporogenesis and Microgametogenesis?

Microsporogenesis is the process of formation of pollen grains (microspores) from the sporogenous tissue. Microgametogenesis is the process of formation of male gametes from the generative cell nucleus that is present inside the pollen grain through mitosis.

What is the function of Megasporogenesis?

Megasporogenesis leads to the formation of four haploid megaspores and later into an embryo sac.

What is Megasporogenesis & explain its process?

Megasporogenesis is defined as the process of formation of haploid megaspores by the meiotic division of diploid Megaspore Mother Cells (MMC) inside the megasporangium (ovule). The haploid megaspore undergoes repeated mitotic divisions to form the embryo sac.

What is micro and Megasporogenesis?

Microsporogenesis involves the formation of microspores from microspore mother cells by meiotic division. Megasporogenesis is the process of arrangement of megaspores from the megaspore mother cell. It occurs inside the pollen sac of the anther. It occurs in the ovule of the ovary.

What is Microsporogenesis and microgametogenesis?

What is the difference between Microsporogenesis and Megasporogenesis?

Microsporogenesis involves the formation of microspores from microspore mother cells by meiotic division. Megasporogenesis is the process of arrangement of megaspores from the megaspore mother cell. It occurs inside the pollen sac of the anther.
