Germination

Germination occurs when a new plant grows out from a seed. All seeds require three conditions for successful germination:

  • Water allows the seed to swell up and all the chemical reactions involved in the growth of the embryo to take place.
  • Oxygen is needed for aerobic respiration which provides the energy the embryo needs to carry out cell division and grow.
  • Warmth is required for the enzymes to carry out respiration and cell division.

As the new plant grows, it produces roots which take in water and minerals from the soil and produces leaves on its shoots which carry out photosynthesis to make food for the plant.
