The fruit develops from the base of ovary, containing developing seeds after pollination and fertilization has occurred. Fruits are a continuation of the flower structure. Therefore lettuce,celery and carrots are true botanical vegetables, while tomatoes, green peppers and squash are botanical fruits. The main functions of fruits are to protect and disperse seeds for reproduction. The seed's function is to form the next generation of plants.
Dispersal takes place by different means.
For example, plumeria are winged and stephanotis seeds have fluff. Dandelion and milkweed are examples from temperate climates. B. Water -dispersed fruit are floatable and resistant to damage from immersion, especially in salt water. C. Animal -dispersed fruits stick to hair, fur or wings, or mud on feet of water birds. In the impatiens plant, the fruit dries out, sections of the capsule twist back,and seeds are forcefully ejected.
