Unscramble the steps: • Under favorable conditions, the seed germinates (sprouts). • A pollen tube grows to the ovule • The ovary around the ovule becomes a fruit (protects & helps spread the seed) • Fertilization: sperm & egg fuse in the ovule • Pollination:pollen moves from anther (male) to stigma (female) • Ovule develops into a seed
Angiosperm Fruits Journal • Compare: a tomato fruit to a silver maple fruit • Draw, color and label: each type of fruit and its seeds. Use a dissecting microscope to help observe some of the detail within the fruits and seeds. Questions: How are the seeds within the fruits dispersed within an environment? How have these fruits adapted to their method of dispersal?
