  3. Magnolia

  4. Bougainvillea
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Hovering birds are the hummingbirds that are the most common flower-visiting birds and are attracted to bright colored flowers that produce nectar. These birds have a long beak and they do not sit on the flower, they hover over it. The flowers of such plants hang (are pendent) so that birds can hover over it and insert the beak in the flower. This type of pollination by means of birds is called ornithophily. The example is which is pollinated by hummingbirds, i.e. Bignonia.
So, the correct answer is A.

Ornithophily is pollination by

  1. Humans

  2. Wind

  3. Birds

  4. Bat
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

Animal vectors are required for pollination in

  1. Mulberry

  2. Cucumber

  3. Maize

  4. Vallisneria
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
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. Entomophily

  2. Ornithophily

  3. Chiropterophily

  4. Anemophily
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chiropterophily is pollination by bats. Flowers pollinated by bats are typically large, nocturnal, produce copious nectar, and emit strong odors to attract bats.
