Roots
Roots are the most important and underground part of a plant, which are collectively called the root system. They are the major part that anchors the plant firmly in the soil. They absorb water and minerals from the soil, synthesise plant growth regulators, and store reserve food material. The apical part of the root is covered by the root cap that protects the root apex.
The direct elongation of radicle leads to the formation of primary roots that grow inside the soil in dicots. It bears lateral roots that are known as secondary and tertiary roots.
In monocots, the primary root is replaced by a large number of roots because it is short-lived. In some plants such as Banyan tree, the roots arise from the parts of the plant and not from the radical. Such roots are known as adventitious roots.
Few plants that grow in swampy areas ave roots growing vertically upwards to get oxygen for respiration. Such roots are known as pneumatophores.
Stem
The stem is the part of the plant which is found above the ground. The bark of trees are brown in colour and younger stems are green in colour. It forms the basis of the shoot system and bears leaves, fruits and flowers. The region where the leaves arise is known as the node and the region between the nodes is known as the internode.
Leaves
Leaves are the most important part of a plant. They contain chlorophyll that helps the plants to prepare their food using sunlight, carbon dioxide and water. A leaf consists of three main parts- petiole, leaf base and lamina.
The petiole keeps the leaf blade exposed to wind and cools the leaf.
The leaf base is a protruding part of a leaf.
The lamina of the leaf contains veins and veinlets that provide rigidity to the leaf blade and help in the transport of mineral nutrients.
Primarily, leaves have three main functions:
Photosynthesis: Green leaves prepare food for plants by using water and carbon dioxide in the presence of sunlight. This process is called photosynthesis.
Transpiration: Other than photosynthesis, leaves play a crucial role in the removal of excess of water from plants through tiny pores called stomata. This is the process of transpiration.
Reproduction: Leaves of some plants helps in reproduction also. For e.g. leaves of Bryophyllum give rise to a new Bryophyllum plant.

Other Parts of Plants
The other parts of a plant include flowers and fruits.
Flowers
Flowers are the most beautiful and colourful part of a plant. They are the reproductive part of a plant. A flower has four major parts, namely,
Petals: It is the colourful part of a flower which attracts insects and birds.
Sepals: Sepals are green leafy parts present under petals and protect the flower buds from damage.
Stamens: This is the male part of the flower consisting of anther and filament.
Pistil: This is the female part of the flower consisting of stigma, style, and ovary.

Fruits
Fruits are the main features of a flowering plant. It is a matured ovary that develops after fertilisation. Some fruits are developed without fertilization and are known as parthenocarpic fruits and the process is known as Parthenocarpy.

Thus, we see how different parts of a plant help in the growth and development of a plant. All the plant parts are beneficial and work in coordination with each other.
