Biology of Insects and Pollination Questions

Multiple choice
  1. birds

  2. droplets of rain

  3. insects

  4. wind

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oak trees are wind-pollinated (anemophilous). They produce inconspicuous flowers with copious, lightweight pollen grains adapted for wind dispersal. Oak pollen is a common allergen because it's wind-borne. Wind pollination is the primary mechanism, not insects, birds, or rain droplets.

Multiple choice
  1. neurohormones

  2. neurotransmitter

  3. pheromones

  4. phytohormones

  5. none of these

C Correct answer
Explanation

The hormonal substances, released by the exocrine glands in the external environment, which serve as a means of communication between members of a particular species are called pheromones.

Multiple choice
  1. APIS INDICA

  2. apis Indica

  3. Apis indica

  4. Apis Indica

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

According to binomial nomenclature rules, the genus name must be capitalized and the species name must be lowercase. Both should be italicized when written. Option C correctly shows 'Apis indica' with proper formatting.

Multiple choice
  1. Apis indica

  2. Apis dorsata

  3. Apis cultiva

  4. Apis florae

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The three main species of honeybees found in India are Apis indica (Indian bee), Apis dorsata (rock bee), and Apis florea (little bee). 'Apis cultiva' is not a valid scientific name for any honeybee species - it appears to be fabricated.

Multiple choice
  1. chemicals

  2. earthworms

  3. birds

  4. insects

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

“Vermi” means worms. So, chemicals, birds and insects cannot do vermicomposting. Vermicomposting is the process of composting by utilising various species of worms, usually red wigglers and earthworms, to create a heterogeneous mixture of decomposing vegetable or food waste. Secretions in the intestinal tracts of earthworms, along with soil passing through the earthworms, makes nutrients more concentrated and available for plant uptake, including micronutrients.

Multiple choice
  1. aphids

  2. honey bees

  3. wasps

  4. all the three

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural parthenogenesis (development from unfertilized eggs) occurs in aphids (cyclical parthenogenesis), honey bees (drones develop from unfertilized eggs), and wasps (some species reproduce parthenogenetically). All three groups exhibit this reproductive strategy.

Multiple choice
  1. Layering

  2. Pollination

  3. Germination

  4. Grafting

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pollination involves transfer of gametes (pollens) from male reproductive part (anther) to female reproductive part (stigma) for fertilization.

Multiple choice
  1. Animals can help in pollination.

  2. Insect pollinated flowers are attractive in nature.

  3. Water can act as agent of pollination

  4. Insects help only in cross pollination.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Insects help in both self and cross pollination.

Multiple choice
  1. Water hyacinth

  2. Venus flytrap

  3. Opuntia

  4. Tapegrass

  5. Prickly pear

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Venus flytrap is a small carnivorous plant as it eat insects. Each trap on a Venus flytrap plant has sensitive hairs that signal the plant when it is touched and cause it to close quickly. The sweet-scented leaves attract insects.
