  5. pollination by insects

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

It is known as chiropteriphily.

Multiple choice
  1. Insect

  2. Wind

  3. Water

  4. Soil

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

Pollinators are agents that transfer pollen grains. Insects (like bees and butterflies), wind, and water all serve as pollinators in different plant species. Soil is the medium in which plants grow but plays no role in pollination.

Multiple choice
  1. breeding

  2. feeding

  3. spreading

  4. flying

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

Destroying mosquito breeding sites (standing water) is a key public health strategy because it eliminates where mosquitoes lay eggs and larvae develop. Feeding places, spreading areas, and flying routes are not targeted for destruction since the goal is preventing reproduction.

Multiple choice
  1. Ant

  2. Mosquito

  3. Beetle

  4. Butterfly

C Correct answer
Explanation

Beetles (Order Coleoptera) are the most diverse group of insects, with over 400,000 described species, making them the most common insect worldwide in terms of species count. Ants are social insects with huge biomass but fewer species, mosquitoes are numerous but less diverse, and butterflies are a much smaller group.

Multiple choice
  1. rapid turgor pressure changes

  2. a passive process requiring no special ability on the part of the plant

  3. specialized “muscle-like” cells

  4. chemical stimulation by the pery

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

  The ability of the Venus Flytrap to capture insects is due to rapid turgor pressure changes.Each side of the trap has three to four sensor hairs, each no longer than 0.2 inches (0.5 centimeters). An insect must trip a hair twice or two hairs within 20 seconds for the trap to respond; this allows it to avoid snapping shut on raindrops or other false alarms. 

Multiple choice
  1. hydrophilly

  2. entomophilly

  3. ornithophilly

  4. none of the above

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

Hydrophily is the correct term for pollination by water. It is a rare form of pollination found in some aquatic plants like Ceratophyllum, Zostera, and Vallisneria. The prefix 'hydro-' refers to water, while '-phily' means 'loving' or 'attraction.' Other terms follow similar patterns: entomophily (insect pollination), ornithophily (bird pollination), anemophily (wind pollination), and chiropterophily (bat pollination). The spelling 'hydrophilly' appears to be a typo in the options.

  3. male bee

  4. sterile female or male bee
