Question

Explain the reproduction of slime moulds during favourable and unfavourable conditions.
*detailed answer plzz*

Answer 1

Myxomycota (division) are commonly referred to as slime molds.

The spores of Myxomycetes are normally globose, uninucelate and haploid. The spore surface may range from almost smooth to reticulate. Spores of P. polycephalum and D. iridis are spiny. The spore wall is composed primarily of cellulose and is only one of two stages where a cell wall is formed. The other stage that forms a cell wall is the microcyst, which is discussed below. Upon germination, the spore will crack open and release a single, uninucelate myxamoeba. The myxamoeba moves by amoeboid motion and ingest food, by phagocytosis, as it does so. As the myxamoebae feeds and grows, they will reproduce, asexually, by mitosis and cytokinesis.

The myxamoeba stage may continue to proliferate for an indefinite period of time if there is available nutrient and the environment remains favorable. In most species, the myxamoeba stage may also vary according to the environment. When free water is available myxamoeba can differentiate into flagellated swarm cells . Although two flagella are present, One the long, anteriorly directed flagellum is visible. The second, very short flagellum is usually not visible. During periods of unfavorable conditions, the protoplast of the myxamoeba or swarm cell can round up and form a thin, cellulose  protecetive layer around itself, called the microcyst , which will protect it from the environment.
