BACKGROUND: flowering plants are normally split into roots, stems, leaves, flowers, and fruit. The is likewise useful to talk about buds (flower, leaf and stem), seeds, trunks and also branches. Roots serve to anchor plants and absorb water and minerals from the soil and also some roots role in food storage. Stems might be found above or listed below ground and provide support for the plant and transport fluids. Some stems have been so dedicated for food storage and also reproduction that they no longer look favor a typical stem (for example potato tuber, iris rhizome, crocus or gladiolus corn). They deserve to be differentiated from root by the existence of buds and leaf scars. Both stems and also roots might have little roots top top them, but only the stems will have actually buds.

Leaves absorb sunlight and also produce the plant"s food with photosynthesis. Flowers room the key reproductive organs, creating pollen and also eggs which hold together in the ovary to produce seeds. The ovary turns right into a fruit. Seed may likewise be found listed below ground (peanut).

There is no scientific distinction between a fruit and a vegetable. To a botanist, a fruit is the plant part produced indigenous the ovary the a flower; the fertilized eggs develop into seeds. For this reason tomatoes, eco-friendly peppers, avocados, squash, cucumbers, corn and other "vegetables" are really fruits. The grains, such as rice, wheat, barley, and also oats, are also considered fruits. That is probably ideal just to explain that the method we define plant parts does not correspond well through the means we normally see the terms "fruit" and also vegetable." If young kids can know that a fruit is a plant component with seeds, it will certainly be a an excellent start.
