Sixteen chemical elements are important in which carbon, hydrogen, and oxygen are supplied by air and water, which comprise about 98% of the fresh weight of the plant, at least 13 other chemical elements, called the essential inorganic nutrients, are needed for plant's growth and survival.he inorganic material obtained from soil which are used as raw material by plants are called mineral nutrients. Absorption utilization and assimilation of inorganic compound or minerals by plants for synthesis of essential material for their growth, development, structure and physiology is called mineral nutrition.

Spermatogeneis is the process of sperm production and involves several steps that leads to the differentiation of cells into functioning sperm cells (spermatozoa). The process occurs in the seminiferous tubules of the testes (testicles). Sperm should be differentiated from the semen which is ejaculated with sexual intercourse. Semen is composed of sperm with fluid from the vas deferens, seminal vesicles, prostate gland, and other accessory glands. Sperm Production in the Testes Where does spermatogenesis occur? The production of sperm is a multi-step process that occurs within the seminiferous tubules which are long hollow coiled tubes in the testes. There are close to 1,000 such tubules measuring some one and a half meters in each testis. The walls of these tubules have sperm in different stages of differentiation, Sertoli cells and interstitial cells.
