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.

What is the 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. Microsporangium is the place where microsporogenesis occurs.

What is the difference between Megasporogenesis and Megagametogenesis?

The difference between the megasporogenesis and megagametogenesis is as follows: Explanation: ... 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 the difference between Microsporangia and Microsporangium?

Answer. Microsporangia are the structures that give rises to male gametes or microspores. It have been taken with plural form while microsporangium in singular way. On the other hand, the megasporangia are structures that give rise to female gamates or megaspores or ovules.

What is the difference between Microspore and Megaspore?

Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes. The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote.

What is the process of Microsporogenesis?

The nucleus of each microspore mother cell undergoes meiosis or reduction division and gives rise to four haploid nuclei. This process is called microsporogenesis. ... These microspores fiurther divide once by mitosis to form two-celled microspore. differentiates into pollen grain.

What do you mean by Microsporogenesis?

Microsporogenesis is the process by which extremely tiny spores are formed in the pollen sacs of seed plants. They eventually develop into pollen grains, which are dispersed and help the plant reproduce. ... Microsporogenesis is similar to megasporogenesis, which produces larger, egglike female reproductive cells.

What kind of structures is formed at the end of Microsporogenesis and Megasporogenesis?

It occurs in the nucellus part of the ovule. In both events, meiosis cell division occurs. The structure formed at the end of microsporogenesis is pollen grain in male gametophyte, whereas the structure formed at the end of megasporogenesis is embryo sac in female gametophyte.

What type of cell division occurs during Microsporogenesis and Megasporogenesis?

Meiosis occurs during both megasporogenesis and microsporogenesis to prodduce haploid male and female gametes.

What is a Megasporangium?

: a sporangium that develops only megaspores.

Is anther a Microsporangium?

The male gametophyte develops and reaches maturity in an immature anther. In a plant's male reproductive organs, development of pollen takes place in a structure known as the microsporangium (Figure 5). The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains.

What is the other name of Microsporangium?

Yes, microsporangium means anther. It is a four-sided structure and consists of four microsporangia, each located at the corner. It helps in the production of microspores or pollen grains, which are produced in thousands of number.

How many wall layers are present in a Microsporangium?

Pollen grains develop inside the microsporangia. Four wall layers, the epidermis, endothecium, middle layers and the tapetum surround the microsporangium. Cells of the sporogenous tissue lying in the centre of the microsporangium, undergo meiosis (microsporogenesis) to form tetrads of microspores.
