When Carpels are fused it is termed as?

If two or more carpels are present, they may be separate from one another (distinct), termed apocarpous, or fused together (connate), termed syncarpous. Because of the frequent fusion of carpels, additional terms are useful in describing the female parts of a flower.

What is the disadvantage of self pollination?

May lead to the weakening of variety or the species due to continued self-pollination, thereby affecting the quality of offspring. Defective or weaker characters of the variety or breed cannot be eliminated. Self-pollination does not yield new varieties, hence fewer chances of improvement in the subsequent generation.

What are the contrivances of self pollination?

The major contrivances of self-pollination are:

  • Bisexuality.
  • Homogamy.
  • Cleistogamy.

What is Homogamy self pollination?

Homogamy is when the anthers and the stigma of a flower are being matured at the same time. The action of self-pollination guides the plant to homozygosity, causing a specific gene to be received from each of the parents leading to the possession of two exact formats of that gene.

What are the benefits of self pollination?

The advantages of self-pollination are as follows:

  • Much surer in bisexual flowers where stamens and carpels mature simultaneously.
  • Indefinite preservation of parental characters.
  • No wastage of pollen grains.
  • Flowers are not required to be showy and large.
  • Nectar and scent are not required to be produced by flowers.

What are the agents of self pollination?

Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower.
