what is the main anatomical difference between young microsporangium and a mature microsporangium?
Answers
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.
This could be taken at plural form while megasporium in singular form.

Answer:
The main anatomical difference between a young and mature microsporangium (also known as an anther) is the developmental stage of the microsporocytes, the cells that give rise to microspores.
Explaination:
Young microsporangium
- In a young microsporangium, the microsporocytes are actively undergoing meiosis, a type of cell division that results in the formation of haploid cells.
- During meiosis, the chromosomes in each microsporocyte are separated and arranged into four haploid cells, each with half the number of chromosomes as the original cell.
Mature microsporangium
- As the microsporangium matures, the microsporocytes complete meiosis and the resulting haploid microspores are surrounded by a thick cell wall to form a protective structure called a pollen grain.
- The mature microsporangium is composed of several layers of tissue, including the tapetum, which provides nutrients to the developing microspores, and the endothecium, which helps with the dehiscence of the microsporangium at the time of pollination.
