Reproduction in Plants Notes

• The seed/s, enclosed in the fruit, needs to separate from its parent plant before it can develop into a new plant.
• Fruits are adapted in different ways to help in dispersal.
• But very often, both fruits and seeds together form the dispersal unit.
• Dispersal takes place by several mechanisms, including wind, water, and a variety of animals.
• In the simplest way, seeds are automatically set free by opening of the fruit.
• An explosive mechanism bursts the fruit open to release the seeds. For example, pea plants, castor, and balsam.
