C Correct answer
Multiple choice
  1. Foul odours from flowers attract flies & beetles

  2. Animals are attracted to flowers by colour and fragrance

  3. Nectar and pollen grains are floral rewards to animals

  4. All

D Correct answer
Explanation

Flowers attract pollinators through various signals like color, fragrance, and foul odors, and offer rewards like nectar and pollen to ensure successful pollination.

Multiple choice
  1. Bees are dominant biotic pollinating agents

  2. Primates (limur), arboreal (tree dwelling)rodents and gecko & garden lizard

  3. Insect pollinated flowers are large,colourful,fragrant & rich in nectar

  4. All

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

Biotic pollination involves a wide range of animals, including insects like bees, as well as vertebrates like rodents, geckos, and birds, which are attracted to specific floral traits.

Multiple choice
  1. Wind pollinated flowers

  2. Water pollinated flowers

  3. Both

  4. None

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

Flowers pollinated by abiotic agents like wind and water do not need to attract pollinators with color or nectar, as these are traits specifically evolved for biotic (animal) pollination.

Multiple choice
  1. Waterhyacinth & waterlily emerge above water & pollinated by insects & wind

  2. Vallisneria pollinated at surface of water through water

  3. Sea grasses submerged in water and pollinated inside water

  4. All

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

Different aquatic plants have evolved different strategies: some like water hyacinth emerge above water and use insects/wind, while others like Vallisneria and sea grasses use water for pollination.

Multiple choice
  1. Example of wind pollination is Corn - cab

  2. Tassels are stigma & style which wave in wind to trap pollen grains

  3. Wind pollination is quiye common in grasses

  4. All

D Correct answer
Multiple choice
  1. Chasmogamous flowers

  2. Cleistogamous flowers

  3. Both

  4. None

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

Cleistogamous flowers do not open, meaning pollination occurs within the closed flower. Therefore, they do not require external pollinators.
