1. What is the function of the tube nucleus?

  • Fuses with 2 nuclei in the ovule to form the endosperm
  • Fuses with a sperm nuclei to form the egg
  • Fuses with the ovary to form the testa
  • Fuses with the micropyle to form the fruit

2. What is pollination?

  • The production of CO2 in a plant
  • The transfer of pollen from anther to stigma
  • The production of an egg cell
  • The transfer of pollen from stigma to anther

3. What is a disadvantage of self pollination?

  • Variation increases within individuals
  • There's a lack of variation, decreasing the chance of survival
  • Favourable gene combinations are retained
  • Energy consumption is high as many gametes must be produced

4. What becomes the fruit?

  • Embryo sac
  • Outer integument
  • Ovary
  • Fertilised ovule

5. Which one of these does the embryo not consist of?

  • Cotyledons
  • Ovule
  • Radicle
  • Plumule




There are some errors in here, the Tube nucleus in the pollen grain controls the growth of the pollen tube before disintegration.

It is the generative nucleus which consists of the two male nuclei. One of these fuses with the polar nucleus to form the triploid endosperm tissues which will become the endosperm and the other fuses with the oosphere to divide by mitosis to become the embryo.
