When the pollen grains are not transferred from anthers to the stigma in flower due to the barrier of fence, it is referred as or when some natural barriers, exist between androecium and gynoecium to check self pollination, it is known
1 heterostyly
2 herkogamy
3 dichogamy
4 cleistogamy
Explanation:
When the pollen grains are not transferred from the anthers to the stigma in flower due to barrier of fence or when some natural barriers exist between androecium and gynoecium to check self pollination, it is known as herkogamy. Some flowers have different lengths of stamens and styles to check the selffertilisaiton is known as heterostyly. When anther and stigma reach maturation at different times, this condition is known as dichogamy.

Gymnosperms have a mode of pollination celled:
1 anemophily
2 zoophily
3 entomophily
4 hydrophily
Explanation:
Gymnosperms have a made of pollination called anemophily. When pollination takes place with the help of wind then it is anemophily. Gymnosperms are produce haploid microspores and megaspores. The male and female cones may be borne on same tree or on different trees. The male and female gamete remains within the sporangia. The pollen grain is released from microsporangium and carried via wind and come in contact with the opening of the ovules borne on megasporophylls.

Which of the following flower shows the features of autogamy?
1 Viola papillionacea
2 Triticum aestivum
3 Cicer arietinum
4 Ricinus communis
Explanation:
Viola papillionacea shows the feature of autogamy. A type of pollination in which pollen grains are transferred from the anther to the stigma of the same flower is known as autogamy. Viola papillionacea belongs to the family violaceae. Their flowers are clestogamy flowers. This type of flowers do not open at all and self fertilization takes place.
