  1. Mulberry

  2. Cucumber

  3. Maize

  4. Vallisneria

Show answer
Correct Option: B
Explanation:
• Mulberry is pollinated by wind.
• Cucumber is pollinated by bees.
• Maize is pollinated by wind.
• Vallisneria is pollinated by water.
Hence, animal vector is required for the pollination of Cucumber. So, the correct answer is B.

  1. Agave

  2. Bombax

  3. Erythrina

  4. Bignonia

Show answer
Correct Option: A
Explanation:
Eight species of birds were observed in contact with open flowers on focal
agaves; of these, rufous hummingbirds were most common. Two additional species, Zenaida asiatica (white-winged dove) and Corvus sp. (one of three species of ravens and crows potentially present in the study area), were observed at open flowers on non-focal plants.
So the correct option is 'Agave'.

Large stout, nocturnal flowers producing copiously, nectar and emitting fermenting fruity odour, are the adaptations for.

  1. a-$3$, b-$2$, c-$1$, d-$4$

  2. a-$1$, b-$2$, c-$3$, d-$4$

  3. a-$4$, b-$1$, c-$2$, d-$3$

  4. a-$4$, b-$2$, c-$1$, d-$3$

  5. a-$4$, b-$2$, c-$3$, d-$1$

Show answer
Correct Option: C
Explanation:
•Zoophily is the pollination by animals.
•Ornithophily is the pollination by means of birds.
•Entomophily is the pollination by means of insects.
•Cheiropterophily is pollination by means of bats.
Hence, the correct match is:
a-4 , b-1 , c-2 , d-3 
So, the correct answer is C.

In Oak tree, the pollination is brought about by.

Correct Option: A

The association between ants and some members of family rubiaceae is

  1. Ornithophily

  2. Entomophily

  3. Myrmecophily

  4. Anemorphily

Show answer
Correct Option: C
Explanation:

Myrmecophily is the symbiotic relationship of ants and plants in which the ants get food and place to stay while plants get a pollinator or a method of seed diepersal. It is widely used by family Rubiaceae which is a family of coffee.

So the correct option is 'Myrmecophily'.

Large stout, nocturnal flowers producing copious nectar and emitting fermenting fruity odor, are the adaptations for.

  1. Entomophily

  2. Ornithophily

  3. Chiropterophily

  4. Anemophily

Show answer
Correct Option: C
Explanation:
Pollination occurs through bats is called chiropterophily and flower is called a chiropterophilous flower. Adaptations in chiropterophilous flower :
1. Flowers open during evening or night. 
2. Flowers are large, dull colored and have a strong scent like that of rotting fruits. 
3. Flowers produce abundant pollen grains. 
4. Flowers produce copious nectar.
5. Flowers are tough so that bats can hold on the flowers.
So the correct option is "Chiropterophily".

Which one is absent in windy areas

botany pollination, fertilization and development of endosperm and embryo agents of pollination environmental conservation and biodiversity pollination and fertilization

  1. Birds

  2. Anemophilous plants

  3. Zoophilous plants

  4. Insects

Show answer
Correct Option: C
Explanation:

Windy areas are favorable for plants in which pollination is done by the wind like corn, willow etc while it is unfavorable for those in which pollination is done by animals as it is very difficult to survive.

So the correct option is 'Zoophilous plants'.

Pollination by bats is called as

  1. Chiropterophily

  2. Omithophily

  3. Malacophily

  4. Entomophily

Show answer
Correct Option: A
Explanation:
Pollination by bats is called as Chiropterophily. Flowers that are pollinated by this mechanism usually are usually pale and nocturnal. The advantage of pollination by bats is that they do long distance dispersal of pollen along with depositing huge amount of pollen on the stigmas.
So, the correct answer is, 'Chiropterophily'.
