<span>In 1944, Oswald Avery identifies DNA (Deoxyribonucleic Acid) as transforming principles. This famous genetic scientist has made great efforts for many steps to find what happened after combinations of some bacteria. After purification, he found a new substance which was a nucleic acid, involving the discovery of DNA after further analysis.</span>
<span>Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis, of which the female equivalent is oogenesis. In mammals it occurs in the seminiferous tubules of the male testes in a stepwise fashion.</span>

<h3><u>Answer;</u></h3>
Within an ovule contained within an ovary of a flower
<h3><u>Explanation;</u></h3>
- Angiosperms are the flowering plants. Megasporangia also called female sporangia produce megasporocytes that yield megaspores.
- The megaspores develop in the megasporangium and develop into the female gametophyte generation.
- The ovule appears to be a megasporangium with integuments surrounding it. Ovules are initially composed of diploid maternal tissue, which includes a megasporocyte. Megaspores remain inside the ovule and divide by mitosis to produce the haploid female gametophyte.
