What are the 6 steps of pollination process?
Terms in this set (7)
- a bee seeks nectar from a flower.
- while gathering nectar from the nectaries the bee brushes against the anthers.
- pollen from the anthers stick to the bee’s hairy body.
- the bee moves to another flower on another plant.
What’s the process of pollination?
Pollination process occurs when pollen grains from the male part of one flower (anther) are transferred to the female part (stigma) of another flower. Once pollination occurs, the fertilized flowers produce seeds, which enable the associated plant to reproduce and/or form fruit. Pollination through wind is an example.
What are the 3 steps of pollination?
Pollination and fertilisation
- Step one: After pollen has landed on the stigma, it grows a pollen tube down through the style to the ovary.
- Step two: The nucleus of the pollen grain travels down the pollen tube and fertilises the nucleus in the ovule.
- Step three: The fertilised ovule develops into a seed.

What are the modes of pollination?
Types of Pollination According to Agent of Pollination Anemophily – pollination by wind, e.g. in many grass plants (Poaceae or Gramineae) and sedges (Cyperaceae). Cantharophily – pollination by beetle. Cheiropterophily – pollination by bat, examples the century plants ( Agave spp.), white saguaro cactus (Carnegiea), some bananas ( Musa spp.). Entomophily – a composite term for pollination by insects.
What are the disadvantages to self pollination?
Disadvantages of self- pollination Since there is no mixing up of genes, there are no new characters or features that are introduced into the lineage of the offsprings. Self- pollination is said to reduce the vigor and vitality of the race as there are no new features introduced. Without new characters introduced, the resultant offsprings’ immunity to diseases reduces.
How does the stucture of the stigma aid in pollination?
These stigmas have feathery structures to capture and trap the drifting pollen grains. Pollination is the deposition of a pollen grain on the stigma. It initiates the fertilization process, allowing the germination of the pollen grain on the stigma. Hence, the structure of the stigma is important in the capturing pollen grains.
