Tag: pollination and fertilization

In night, colour of flowers are not detected by insects, so night blooming flowers are generally scented for attracting insects for pollination. Therefore, pollinators are attracted to their aroma.

So, the correct answer is A.

Malacophily is the pollination of flowers by means of snails and slugs.

Myrmecophily is the pollination of flowers by means of ants.

Entomophily is the pollination of flowers by means of insects.

Ornithophily is the pollination of flowers by means of birds.

So, the correct answer is B.

Pollination which occurs by means of insects is known as Entomophily.

Pollination which occurs by means of birds is known as Ornithophily.

Pollination which occurs by means of bats is known as Chiropterophily.

Pollination which occurs by means of snails and slugs is known as Malacophily.

So, the correct answer is D.

In Malacophilous plants, flowers are pollinated by snails and slugs. Example, some water plants such as Lemna and members of Poaceae.

In Ornithophilous plants, flowers are pollinated by means of birds. Example, Begonia is pollinated by the hummingbird.

In Chiropterophilous plants, flowers are pollinated by bats. Example, Adansonia (baobab tree).

In Anemophilous plants, flowers are pollinated by wind. Example, Maize, grasses etc.

So, the correct answer is C.

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.

Pollination by humans can occur mechanically only .

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.

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.
