Reproductive systems

A closer look at the cells and tissues involved in reproduction can help us to understand this vital process.

Experiments

• Comparing the flower structure of different angiosperms
  Study the detailed anatomy of flowers by dissection and the general form by studying images of flowers. Deduce mechanisms of pollination.
• Observing the growth of pollen tubes
  Observe the germination of pollen grains from a range of flowers in sucrose solutions with differing concentrations of mineral salts medium.
