  • Pollen grains are formed in the anthers by meiosis; seeds in the ovary by fertilization
  • Pollen grains are very tiny, even microscopic; seeds may be as small as 1mm across to as large as 50cm
  • Pollen grains are a single cell (similar to sperm); seeds are multicellular
  • Its function is to carry the male characteristics of the plant to fertilize the egg cell; seeds are there to develop into a new plant when the conditions are favourable
