Flowers are the reproductive organs of angiospermophytes.  You will get the chance to disect one, and to draw and label it.  Some flowers are pollinated by wind, others by insects.  We’ll focus on the insect pollinated ones in this topic.  You will also need to be able to distinguish between these three processes:- pollination, fertilization and seed dispersal.

We’ll then take a look at seeds and seed structure, and the process of germination.  Finally we will learn about phytochromes and their role in controlling flowering in long-day and short-day plants.  Read about photoperiodism here.
