An ideal flowering plant can be divided into root, stem, leaves, flower and fruit etc.
Shoot: The part of the plant that remains above the soil is called shoot. Shoot consists of stem, leaves, flower and fruit. The stem has the node, inter node and apical bud. The flowers grow at the axis of the leaves. Flowers have calyx, androcium, Corolla and ovary.
Let examine the parts using the diagram of the chilli plant given.
- Stem: It is the part of the plant connected to the tap root and remains above the soil. The stem has a node and internode. Leaves originate from the nodes. Stem bears the weight of leaves and branches.
- Leaves: It is a thin, extended green outgrowth of the stem and the branches. Food is produced in the leaves.
- Flower: In chilli plant, small white flowers grow out of the axis of the leaves. These flowers mature into fruit, e.g. chilli.
- Fruit: When flower matures, it falls off. The remaining part of the base of the fallen flower becomes fruit. After maturity, ovary turns into fruit. The fruit of the chilli plant is the chilli itself.
- Root: The part of the plant with no node, inter node and apical bud is the root. Generally, people think that the part of the plant that remains below the soil is the root. In most cases, this is worth saying. However, in special cases, stem, leaves, flower and fruit grows under the soil.
For example: ginger, turmeric, onion etc. You will learn more about it in the higher class.
Roots usually develop from radical. Leaves, fruits or flowers do not grow, on roots. Roots generally grow downwards. The radical grows into the tap root. Secondary root originates from tap (primary) roots; similarly, tertiary root originates from secondary roots.
