Pollination by snail and slug is known as

  1. Ornithophilous

  2. Chiropterophilous

  3. Entomophilous

  4. Malacophilous
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are different types of pollination depending upon the agent involved in it. Pollination by bird is known as ornithophilous pollination. Chiropterophilous is a type of pollination in which pollination occurs by bats. Entomophilous is a type of pollination in which pollination occurs by insects. Pollination by snail and slug is known as malacophilous pollination. 

Thus, the correct answer is option D.

  3. Bats

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

Chiropterophily is pollination of plants by bats. Bat pollination of most common in tropical and desert areas that have many night blooming flowers. Just like bees and birds that pollinate, nectar consuming bats have evolved ways to find and harvest the nectar. Nectar bats have long tongues and can hover like hummingbirds. In turn, the flowers attract bats with their light-coloured petals, large bolossoms, fruity aromas and plentiful nectar.

Which of the following is a characteristics for ornithophily?

  1. Scented flowers

  2. Bright red coloured flowers and inflorescence

  3. White coloured funnel shaped large corolla

  4. Yellow flower with nectaries at the base of the corolla tube
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Ornithophily is pollination by birds, characteristic is presence of colored flowers ( mostly red) with nectaries. The orientation of the stigma and anthers is to facilitate pollen transfer for cross pollination. 
So, the correct answer is 'Yellow flower with nectaries at the base of the corolla tube'

  1. Cheiropterophily

  2. Entomophily

  3. Ornithophily

  4. Myrmecophily
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollination is the transferring of pollen grains from the male anther of a flower to the female stigma. Pollination by the agency of ants is called myrmecophily. Pollination by bats, insects and birds are called cleiropterophily, entomophily and ornithophily respectively.

Some seeds are dispersed by animals ,especially spiny seeds with hooks which get attached to the bodies of animals and are carried to  distant places. Examples is/are -

  1. Xanthium and urena

  2. Xanthium

  3. urena

  4. Cocount
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The seeds of the fruits get dispersed by different methods. Xanthium and Urena are the plants in which the fruits produces seeds having structures like spines or hooks. These structures are used for clinging the seeds on the body of the animals and get carried away with them and get dispersed.

Thus, the correct answer is option A.
