8.4. Reproduction of fungi ELTE TTK ONLINE. Microbial Reproduction and Growth During their growth cycles, microorganisms undergo reproduction many times, causing the numbers in the population to increase dramatically. In fungi, unicellular algae, and protozoa, reproduction involves a duplication of the nucleus through the asexual process of mitosis and a splitting of the cell in cytokinesis., Nutrition, Classification and Reproduction of Fungi Nutrition. Unlike green plants, which use carbon dioxide and light as sources of carbon and energy, respectively, fungi meet these two requirements by assimilating preformed organic matter; carbohydrates are the preferred nutrient source. Fungi can readily absorb and metabolize a variety of soluble carbohydrates, such as glucose, xylose.

Asexual reproduction is a form of reproduction in which one parental organism produces offspring that are genetically identical to each other and to the parent. The daughter cells are clones, and asexual reproduction is an example of natural cloning. Another definition of asexual reproduction is that it is a mode of reproduction that gives offspring without the involvement of gametes.

During reproduction of fission yeasts the parent cell elongates (Fig. 217A & B), the nucleus divides into two daughter nuclei, and gradually a transverse partition wall is laid down somewhat near the middle starting from periphery to the centre dividing the mother cell into two daughter cells (Fig. 217 C & D).

    Fungus - Sexual reproduction: Sexual reproduction, an important source of genetic variability, allows the fungus to adapt to new environments. The process of sexual reproduction among the fungi is in many ways unique. Whereas nuclear division in other eukaryotes, such as animals, plants, and protists, involves the dissolution and re-formation Microbial Reproduction and Growth During their growth cycles, microorganisms undergo reproduction many times, causing the numbers in the population to increase dramatically. In fungi, unicellular algae, and protozoa, reproduction involves a duplication of the nucleus through the asexual process of mitosis and a splitting of the cell in cytokinesis.
