Night blooming flowers attract pollinating insects with the help of

  1. Aroma

  2. Nectar

  3. Edible pollen

  4. All of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
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.

Adansonia (Baobab Tree) is

  1. Malacophilous

  2. Ornithophilous

  3. Chiropterophilous

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

  1. Bignonia

  2. Peepal

  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.

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.
