In the process of sporulation, spores are formed from the vegetative cells, when the environmental conditions are not favorable. Sporulation may be referred to as the adaptive response by which the organisms survive in the given adverse conditions such as, extreme cold or heat, radiation, and lack of nutrition, etc. As compare to the … Read more

Spermatogenesis, the basic and development of the sperm cells in the male reproductive organs, also known as the testes. The testes are made up of numerous thin, tightly coiled tubules called seminiferous tubules; the sperm cells are formed in the walls of the tubules. Within the walls of the tubules, also, are many randomly … Read more
Surface Chemistry: Types of emulsions An emulsion is a colloidal dispersion of liquid droplets (dispersed phase) of a certain size within a second immiscible liquid (continuous phase).An emulsifying agent is crucial for the formation of an emulsion and for maintaining the emulsion’s stability to increase its shelf life.Emulsions are usually made by vigorously mixing the … Read more
Single-cell protein refers to protein gotten from cells of microorganisms like yeast, fungi, algae, and bacteria, which grown on various carbon sources for synthesis. SCP production may have the potential for feeding the ever-increasing world population. Some quantities of SCP can be produced in a single day. As a source of protein, it is very … Read more
The arouse for seed and fruit formation was the act of fertilization. This resulted to fertilization of double cangiosperms which produces two structures. That is, a diploid zygote or oospore and a triploid primary endosperm cell. Nutritive tissue which is also called endosperm is realized as a result of the process. The embryo is forms … Read more
