In the ovary the pollen mixes with the egg to produce new seeds. • Seed Dispersal: • In order to stop related plants competing with one another seeds are transported to grow in another area. This can be done through the following methods: • Wind / Water dispersal • Animal Dispersal • Spinning Dispersal • Pollination: • Pollination occurs when the pollen from the anther (male part) is transferred onto the stigma (female part). • There are three ways plants can be pollinated • Wind Pollination • Animal Pollination • Water Pollination • Germination • If a seed lands in an area where conditions are good the seeds will begin to develop new shoots and roots. The three conditions required are: • Water supply • Oxygen • Warmth
