Question

explain the types of pollination in brief​

Answer 1

Answer:

Pollination: Is defined as the deposition of pollen grains on the stigma of a flower from anthers belonging to the same flower, same plant or a different plant.

Pollination is of two types  

Self pollination - Stigma receiving pollen grains from the same flower  

Cross pollination - Stigma receiving pollen grains from a flower on the same plant or a different plant

Wind and insects are two agents of pollination, called as Anemoplily and Entomophily respectively

Example of wind pollination - Grasses, Gymnosperms etc

Example of insect pollination - Rose, Euphorbia sps etc

Pollination and fertilization - Suitable pollination leads to compatible pollen grains being deposited on the stigma, leading to pollen tube development and fertilization.

Answer 2

$\sf \fbox \red{ANSWER}$

Pollination is a biological process in which the pollen grains are transferred from an anther (male part of a flower) to the stigma (female part of a flower). There are two types of pollination:

★ Self-Pollination

→ Self-pollination is referred to as the primary type of pollination, which occurs by transferring the pollen grains directly from the anther into the stigma of the same flower

★ Cross-Pollination

→ Cross-Pollination is referred to as the complex type of pollination during which the pollen grains are transferred from the anther of one flower to the stigma of another flower.

ADDICTONAL INFORMATION

★ Name the plants which undergo Cross pollinations?

→ Most plants use cross-pollination. Cross-pollination is mainly seen in dark and bright coloured flowering plants, where insects like butterflies and honey bees are attracted by their bright coloured flowers. Apples, tulips, lavender, strawberries, beans, dandelions are some examples of plants with cross-pollination.

★ Air pollination is mainly observed in?

→ Wind pollination or anemophily is a type of pollination wherein pollen is transferred by the wind. The majority of plants under the order Poales are anemophilous, rice, wheat, rye, corn, and barley are all wind-pollinated, even gymnosperms. Some of the common anemophilous plants are sweet chestnuts, Oaks, pecans, alders, and members of the Juglandaceae family.
