Chapter 6: Sexual Reproduction in Plants

Which of the following groups represents the female parts of a flower?

• Pollen grains, anther & style

• Stigma, ovary & filament

• Ovary, style & stigma

• Anther, filament & stamen

What is pollination?

• The transfer of pollen from stigma to anther

• The transfer of pollen from stigma to ovary

• The transfer of ovule from anther to stigma

• The transfer of pollen from anther to stigma

The part of the flower where the ovules are found?

• Ovary

• Stigma

• Style

• Filament

The part of stamen where the pollen grains are produced?

• Anther

• Filament

• Style

• Stigma

Diagram shows the pollen grain produces by plant X. Name the pollination agent for plant X?

• Wind

• Water

• Insect

The diagram shows a flower. In which structure A, B, C or D does seeds develop?

• A

• B

• C

• D

Which of the following statements is true about bisexual flower?

• A flower that consists of carpel only

• A flower that consists of stamen only

• A flower that consists of both carpel and stamen

• A flower that consists of sepal and petal

Which of the following pairs is mismatched?

• Anther - Produces microspores

• Ovary - Develops into fruit

• Carpel - Produces pollen grains

• Stigma - Receives pollen grains

Even after destroying the generative nucleus with a laser

beam, the pollen grain of flowering plant germinates

and produces normal pollen tube. This is because?

• Tube nucleus is not damaged

• The destroyed generative nucleus stimulates pollen

  growth

• Laser beam stimulates growth of pollen tube

• The region of emergence of generative nucleus is not harmed

Which of the following is the correct sequence for the

stages in the development of pollen grain?

• Tetrad → pollen grains → microspore mother cell →

  mature pollen grains

• Microspore mother cell → pollen grains → mature

  pollen grains → tetrad

• Microspore mother cell → tetrad → pollen grains →

  mature pollen grains

• Tetrad → microspore mother cell → pollen grains →

  mature pollen grains
