What is the difference between micro and Megasporogenesis?
What is the difference between micro and Megasporogenesis?
Hint: Microsporogenesis is the procedure in which microspore mother cell undergoes meiosis as well as it forms haploid microspore tetrad. It reaches in the pollen sac of anther. Megasporogenesis is the procedure in which the megaspore mother cell undergoes meiosis as well as it forms megaspore in the nucleus region.
What are the main differences 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 Micro Sporogenesis?
Microsporogenesis comprises the events which lead to the formation of the haploid unicellular microspores. During microsporogenesis the diploid sporogenous cells differentiate as microsporocytes (pollen mother cells or meiocytes) which divide by meiosis to form four haploid microspores.
What is difference between Microsporogenesis and Microgametogenesis?
Microsporogenesis vs 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 mega Sporangium?
megasporangium in British English (ˌmɛɡəspɔːˈrændʒɪəm ) nounWord forms: plural -gia (-dʒɪə) the structure in certain spore-bearing plants in which the megaspores are formed: corresponds to the ovule in seed plants. Compare microsporangium. Collins English Dictionary.
What is Microsporogenesis according to Ncert?
The process of formation of microspores from a pollen mother cell (PMC) through meiosis is called microsporogenesis. The nucleus of a pollen grain divides mitotically to form a vegetative and generative nucleus.
What is Microspore and Genesis?
This is all right there in the word: micro- means “tiny,” sporo refers to spores, and genesis refers to creation or generation. So, microsporogenesis is the generation of tiny spores inside of plants. Each of these four tiny spores then becomes one male pollen grain.
What is the common name for megasporangium?
megasporangium A spore sac that contains megaspores. In flowering plants, this is known as the ovule. See also HETEROSPORY and MICROSPORANGIUM.
What is Microsporogenesis by BYJU’s?
Definition. Microsporogenesis involves the formation of microspores from microspore mother cells by meiotic division. It occurs inside the pollen sac of the anther. Microsporogenesis results in haploid microspore forming from the diploid microspore mother cell.
What is Microsporogenesis by biology discussion?
During microsporogenesis (i.e., development of microspores or pollens) the nucleus of each microspore mother cell undergoes meiosis or reduction division ultimately giving rise to four haploid (i.e., possessing ‘n’ number of chromosomes) nuclei (Fig. 404—F & G).
What is the difference between Microsporangium and Megasporangium?
The main difference between megasporangium and microsporangium is that the megasporangium is the sac where the megaspores or female gametes are produced whereas the microsporangium is the sac where the microspores or male gamates are produced.
What is the difference between Microgametogenesis and Megagametogenesis?
The difference between microgametogenesis and megagametogenesis. is that “microgametogenesis” is the gametogenesis of microgametes and “megagametogenesis” is the development of a megaspore into an embryo sac.
