Explanation:
Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.
<h3>What is spermatogenesis?</h3>
Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.
Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.
Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.
The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

Answer:
Interphase - There are 3 subphases called - G1 , S and G2 . In these subphases, DNA material is duplicated, and essential proteins for cell division are formed.
Prophase - the nuclear envelop and nucleolus disappears and condensed DNA forms chromosomes that are short in size.
Metaphase - the form of two sister chromatids are arranged in the middle of the metaphase/equatorial line. Two centrioles are found at two poles of the cell which initiate the formation of spindle fibers.
Anaphase - spindle fibers are formed and can be observed. These fibres attach with the kinetochore present in the centromere of chromosomes and these chromatids now start separated by pulling and pushing force of spindle fibers in opposite poles
Telophase - chromatids reach at destination pole and then nuclear envelop starts creating again in both poles. Nucleolus reappears and now in a cell two nucleus are found.

Explanation:
Bronchial/Tracheal cells are from the lining of the bronchi/trachea, the network of tubes used to convey air to the lungs. Bronchial/Tracheal cells are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body. These cells generate mucus and a number of other compounds, which play an important role in respiration.
