Roots The part of the plant that remains under the soil in most of the plants is called the root. These help in fixing the plant firmly into the soil so that the plant does not fall and thus help the plant in standing erect (upright) above the soil. They absorb water and the dissolved minerals from the soil which are used by the plant in the process of photosynthesis for preparing its food. Roots also store the extra food within them which is used when required by the plant. Stem The part of the plant that remains erect (upright) above the soil is called the stem.

Pistil: The innermost part of a flower. It has three parts - stigma, style and ovary. Stigma: The uppermost part with an opening. Style: The tube that connects the stigma and the ovary. Ovary: The lowermost swollen base. It contains small bead-like structures called ovules. A plant has two main systems. These are: The root system and The shoot system Root system The part of the plant that grows / remains under the soil in most of the plants is called the root. The root system contains primary roots and secondary roots / root hairs. Shoot system The part of the plant that grows erect above the ground in most of the plants is called the shoot.
