Cytology is the branch of biology and medicine concerned with the structure and function of animal and plant cells. But here we discuss human haploid cells (spermatozoon and ovum/egg), zygotes, blastomeres, bacterial cells, unicellular parasitic cells, yeasts, etc.
The human egg cell, also called ovum (plural ova) is a haploid cell having 23 chromosomes. It is the female reproductive cell, or gamete having a size of approximately 120 μm.
It is also called spermatozoon ( pleural spermatozoa) a motile sperm cell or moving form of the haploid cell (having 23 chromosomes) that is the male gamete. A spermatozoon unites an ovum to form a zygote.
Bacteria are single-celled microorganisms. The cell structure is simpler than that of other microbes as there is the absence of a well-defined nucleus or membrane-bound organelles and chromosomes composed of a single closed DNA circle.
Yeasts are eukaryotic, single-celled microorganisms that come under the fungus kingdom. Yeast cells of Candida are rounded to oval, 3–8 μm in diameter while Cryptococcus is 5 to 10 µm.
