formation of seed and fruit

• by what process does a zygote turn into a diploid embryo

  by mitosis
• what does a diploid embryo consist off

  a plumule, a radical and one or two cotyledons
• What is the plumule?

  developing shoot
• what is a radicle

  developing root
• by what process does a triploid endosperm nucleus turn into endosperm tissue

  by mitosis
• what is endosperm tissue

  this is an important food storage in cereal grains
• give an example of a plant where endosperms are needed

  wheat
• what does the ovule turn into

  a seed
• what does the ovary wall develop into i plants


  a fruit wall
• what will a fruit wall enclose

  a seed
• what will integuments develop into

  the testa
• what is the testa

  Tough seed coat
• what happens to the micropyle after fertilisation in plants

  it will remain as a pore in the testa
• what will the funicle develop into

  a scar called the hilum
• give and example of a dicotyledon

  a broad bean
• what is meant by a dicotyledon

  this means that they have two seed leaves (cotyledons)
• what is found between the two cotyledons in a dicotyledon

  an embryo lining
• what happens to the endosperm in a broad bean seed

  the endosperm is absorbed into the cotyledons
• what is meant by a broad bean being non endospermic


  it doesn't have a endosperm
