    Learning objectives
    • List three functions of a seed and identify its structures.
    • Describe the process of seed germination.
    • List the external factors required for seed germination.
    • Understand dormancy and how the skilled plant propagator overcomes it.

    Seeds are key to feeding the world’s population as a nutrition and calorie source and for the propagation of most crops. In addition, being a fusion of paternal (pollen) and maternal (egg) genetic material, seeds create diversity; evolution acts on this diversity, and plant breeders take advantage of it to improve crops.
