Ornithophily is pollination by

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

  1. Humans

  2. Wind

  3. Birds

  4. Bat

Show answer
Correct Option: C
Explanation:
Pollination by humans can occur mechanically only .
Pollination which occurs by means of wind is called Anemophily.
Pollination which occurs by means of birds is called Ornithophily.
Pollination which occurs by means of bats is called Cheiropterophily.
So, the correct answer is C.

A plant pollinated by bats is

  1. Ophrys

  2. Salvia

  3. Kigellia

  4. All of the above

Show answer
Correct Option: C
Explanation:
Pollination of flowers which occurs by means of bats is called Chiropterophily. Example of plant pollinated by a bat is Kigelia (also known as sausage tree) which is pollinated by the bat Micropterus. Salvia has a turnpipe mechanism of pollination and is pollinated by bee. Ophrys is pollinated by a moth Colpa aurea (hairy wasp) and they both possess a relationship of pseudocopulation.
So, the correct answer is C.

Bees are important to agriculture as they.

  1. Produce wax

  2. Perform pollination

  3. Prevent pollination

  4. Produce honey

Correct Option: B
Animal vectors are required for pollination in

  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.

Crows helps in the pollination of

  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.

  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 

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

  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'.
