Multiple choice botany the flower pollination and its types germination sexual reproduction in plants

Plants are able to produce fruits with the help of insects as they are

  1. Help in aestivation

  2. Help in pollination

  3. Help to overcome dormancy

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs. After pollination, the plants produce fruits.

So, the correct answer is 'Help in pollination',

Multiple choice botany the flower pollination and its types germination sexual reproduction in plants

Pyrilla is a

  1. A character of ancient Greek mythology

  2. An insect pest

  3. Disease of teeth and gums

  4. A building heated by solar energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Pyrilla is the most destructive foliage-sucking pest of sugarcane. Heavy rainfall followed by 75-80% humidity, intermittent drought periods, high temperature (26-300c) and wind movement favours rapid build-up of the pest. Cane yield loss is about 28% while 1.6% unit loss in sugar content. Due to continuous desapping by large number of hoppers, top leaves in the affected canes dry up and lateral buds germinate. The hoppers exude a sweet sticky fluid known as honeydew, which promotes quick and luxuriant growth of the fungus, capanodium species and as a result the leaves are completely covered by the sooty mould.
So the correct option is 'an insect pest'.
