Cytoplasm- It is a jelly-like substance present inside the cell.All the cell organelles are suspended in it. Not all bacteria have the ability to form endospores; however, there are a number of clinically significant endospore-forming gram-positive bacteria of the genera Bacillus and Clostridium. The cell cycle length is highly variable within the different cell types. Most undergo some form of asexual reproduction, such as binary fission, to produce two daughter cells.In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method. An early embryonic cell has a turnover range of a few hours. This extra-chromosomal piece of DNA participates in cell division and confers the bacterial cell with properties such as antibiotic resistance and the ability to infect other cells known as pathogenicity. An early embryonic cell has a turnover range of a few hours. All cells in the body ( somatic cells), except those that give rise to the eggs and sperm (gametes), reproduce by mitosis .
