  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'.

Animals assist with

  1. Pollination and seed dispersal

  2. Control of plant growth and response

  3. Translocation of organic nutrients

  4. Asexual propagation of plants

Show answer
Correct Option: A
Explanation:

Pollination is when pollen grains from an anther, the male portion of a flower, are transferred to a female part in the flower, known as the stigma. Zoophily is a form of pollination whereby pollen is transferred by animals. Zoophilous species frequently evolve mechanisms to make themselves more appealing to the particular type of pollinator. Seed dispersal is the movement or transport of seeds away from the parent plant. Plant species transported externally by animals can have a variety of adaptations for dispersal, including adhesive mucus, and a variety of hooks, spines and barbs

So, the correct answer is 'pollination and seed dispersal'

Myrmecophily is characterised by

  1. Plants harbouring ants

  2. Plants storing food underground

  3. Plants imitating the habit of animals

  4. Plants with small leaves

Show answer
Correct Option: A
Explanation:

Myrmecophily is the symbiotic relationship between plant and ants in which plants provide food to plant or place to hide eggs and ants help them in pollination. 

So the correct option is 'Plants harbouring ants'

Pollination by insects is called

  1. Entomophily

  2. Chiropterophily

  3. Anemophily

  4. Zoophily

Show answer
Correct Option: A
Explanation:

Pollination by insects is entomophily. Insects are the most common biotic agents of pollination. Bees are the most common insect which acts as pollinating agents. Other insect pollinators are butterflies, flies, beetles, wasps, ants, moths. Flowers are brightly colored and scented to attract the insects. Majority of insect-pollinated flowers are large-sized. Entomophily occurs in Calotropis, Ficus, Salvia, etc.
