Biology of Insects and Pollination Questions

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

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

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.

Bees are important to agriculture as they.

  1. Produce wax

  2. Perform pollination

  3. Prevent pollination

  4. Produce honey
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bees are the most important pollinators for many agricultural crops, facilitating the transfer of pollen necessary for fruit and seed production.

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.

The association between ants and some members of family rubiaceae is 

  1. Ornithophily

  2. Entomophily

  3. Myrmecophily

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

Large stout, nocturnal flowers producing copious nectar and emitting fermenting fruity odor, are the adaptations for.

  1. Entomophily

  2. Ornithophily

  3. Chiropterophily

  4. Anemophily
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Pollination occurs through bats is called chiropterophily and flower is called a chiropterophilous flower. Adaptations in chiropterophilous flower :
1. Flowers open during evening or night. 
2. Flowers are large, dull colored and have a strong scent like that of rotting fruits. 
3. Flowers produce abundant pollen grains. 
4. Flowers produce copious nectar.
5. Flowers are tough so that bats can hold on the flowers.
So the correct option is "Chiropterophily".

Which one is absent in windy areas

  1. Birds

  2. Anemophilous plants

  3. Zoophilous plants

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

Windy areas are favorable for plants in which pollination is done by the wind like corn, willow etc while it is unfavorable for those in which pollination is done by animals as it is very difficult to survive.

So the correct option is 'Zoophilous plants'.

Pollination by bats is called as

  1. Chiropterophily

  2. Omithophily

  3. Malacophily

  4. Entomophily
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Pollination by bats is called as Chiropterophily. Flowers that are pollinated by this mechanism usually are usually pale and nocturnal. The advantage of pollination by bats is that they do long distance dispersal of pollen along with depositing huge amount of pollen on the stigmas.
So, the correct answer is, 'Chiropterophily'.

Myrmecophily is characterised by 

  1. Plants harbouring ants

  2. Plants storing food underground

  3. Plants imitating the habit of animals

  4. Plants with small leaves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Myrmecophily is the symbiotic relationship between plant and ants in which plants provide food to plant or place to hide eggs and ants help them in pollination. 

So the correct option is 'Plants harbouring ants'

Pollination by insects is called

  1. Entomophily

  2. Chiropterophily

  3. Anemophily

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

Pollination by insects is entomophily. Insects are the most common biotic agents of pollination. Bees are the most common insect which acts as pollinating agents. Other insect pollinators are butterflies, flies, beetles, wasps, ants, moths. Flowers are brightly colored and scented to attract the insects. Majority of insect-pollinated flowers are large-sized. Entomophily occurs in Calotropis, Ficus, Salvia, etc.

In entomophily, pollinating agents are

  1. Insects

  2. Bats

  3. Birds

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

In entomophily, insects are the pollinating agents. Insects are the most common biotic agents of pollination. Bees are the most common insect which acts as pollinating agents. Other insect pollinators are butterflies, flies, beetles, wasps, ants, moths. Majority of insect-pollinated flowers are large-sized. These flowers are scented, colorful and fragrant and contain nectaries to attract insects. 

Hence, option A is the correct answer.
