- Asexual Reproduction: In this type, a single parent organism produces offspring without the involvement of gametes. The offspring are genetically identical to the parent. This method is observed in organisms

Duringreproduction, usually bycell division, the overlapping shell halves separate, and each secretes a (usually) smaller bottom half. Thus, individual diatoms formed from successive bottom halves show a progressive decrease in size with each division. In a few months there can be as much as a ...
Instead, reproduction relies on the separation of a body fragment from the maternal organism on the background of somatic cell proliferation. Agametic reproduction allows rapid expansion within distinct ecological niches, as well as effective multiplication even in the absence of a sexual partner. ...
