1 small, brightly coloured, producing large number of pollen grains
2 small, producing large number of dry pollen grains
3 large producing abundant nectar and pollen
4 small, producing nectar and dry pollen
Explanation:
Colour less, odourless, nectarless, small producing large number of dry pollen flowers are anemophilous \& nectorless are small pollens can be carried easily even with slow wind. Large, brightly Coloured and nectar producing flowers are entomophilous.

Both, autogamy and geitonogamy are prevented in:
1 Castor
2 Maize
3 Papaya
4 Cucumber
Explanation:
Papaya is dioecious plant hence only prefer xenogamy (pollination). Autogamy and geitonogamy are the mode of self pollination cucumber, maize and castor are monoecious plants. In Autogamy pollen falls on stigma of the same flower. While in geitonogamy pollens from a flower on the same plants. Papaya is dioecious plants thus both autogamy and geitonogamy are prevented in it.

Which one of the following statements is correct?
1 Geitonogamy involves the pollen and stigma of flowers of different plants
2 Cleistogamous flowers are always autogamous
3 Xenogamy occurs only by wind pollination
4 Chasmogamous flowers do not open at all
Explanation:
Cleistogamous flowers are the flowers which are bisexual and never opens and always autogamous. - Xenogamy occurs by Hydrophily, Anemophily, Entomology and other pollinating agents. - Chasmogamous flowers are open flowers which shows both self pollination and cross pollination. - Geitonogamy is type of self-pollination in which pollen of flower get deposited on the stigma of other belonging to same plant.

Wind pollination is common in :
1 Orchids
2 Legumes
3 Lilies
4 Grasses
Explanation:
The pollination of wind known as Anemophily. It is commonly seen among grasses or monocots. - Plants produces large abundant pollen grain. - Flower less coloured or white. - They have small flower - Pollination in grasses occurs through the wind pollination.

Anemophily type of pollination is found in
1 Salvia
2 Bottle brush
3 Vallisneria

Explanation:
Wind pollination is also known as anemophily. In this type of pollination, pollen grains are dispersed by air or wind. It occurs in coconut plants. E.g. Coconut, Pines, Spruce etc.
