Structure of the seed

BROAD BEAN

  • The broad bean is classed as a dicotyledon, as it has two seed leaves.
  • Food store is absorbed into the cotyledons.

MAIZE

  • Maize is a monocotyledon,as it has only one seed leaf.
  • Food store surrounds the seed leaves.

Germination of Broad Bean (Vicia Faba)

Dormancy: a period when active growth is suspended. Germination will occur when specific conditions are met.

After a period of dormancy, and with a favorable environment, food stores will be mobilised and the seed will germinate.

  • A suitable temperature: enzymes need the optimum temperature, this varies from species to species.
