Question

What is autogamous?

Answer 1

Autogamy, also known as self-fertilization, is the fusion of two gametes from the same individual. Self-pollination, a reproductive mechanism used by many flowering plants, is the most common form of autogamy observed. However, autogamy has been observed in protist species as a mode of reproduction.

Complete answer:
Flowering plants engage in autogamy on a regular basis, whereas the protists that engage in autogamy only do so in stressful environments. Autogamous pollination is a type of self-pollination in which the ovules are fertilized by pollen grains from the same flower.

Blossoming plants take part in auto gamy routinely, while the protists that participate in autogamy just do as such in upsetting environments. Paramecium Aurelia is the most commonly read protozoan for autogamy.

The most commonly studied protozoan for autogamy is Paramecium aurelia. Paramecium aurelia, like other unicellular organisms, reproduces asexually by binary fission or sexually via cross-fertilization. However, when exposed to nutritional stress, Paramecium aurelia undergoes meiosis and subsequent fusion of gametic-like nuclei, according to research.

One of these potential gametic nuclei will divide twice more. Two of the four daughter nuclei produced by this step become anlagen, or cells that will become part of the new organism. The other two daughter nuclei develop into gametic micronuclei that will self-fertilize autonomously. These nuclear divisions are most visible when the Paramecium aurelia is subjected to high temperatures.

Note: The transfer of pollen grains from the anther to the stigma of the same flower is referred to as autogamy, whereas geitonogamy is the transfer of pollen grains from the anther to the stigma of another flower of the same plant.
