There are various plant parts and they are:

<Roots

<Stem

<Leaves

<Flowers

<Fruit

Roots:

Roots grow under the ground.Without roots,no plant or tree can survive.They would not grow and bear fruits as well.Roots absorb water and nutrients from the soil. Their main function is to keep the plants erect in their place. The roots have tiny hairs which take in minerals and water from the soil and passes on to the main root;from there they are sent to different parts.

Stem:

Stems grow above the ground and have branches, leaves and flower buds. They also bear buds, which are generally green in the early stages. The function of a stem is to carry water and nutrients from the roots to the leaves and transport the food produced by the xylem tubes (move water) and phloem tubes (move food).The stem also supports the plant.

Leaves:

Leaves are the most active and noticeable part of the plants. They are the most photosynthetic organ of a plant. The shape and structure of leaves vary from plant to plant. They can be tubular, feathery, needle like, cupped, smooth,sticky fragrant or waxy.The main function of the leaves is to prepare food. Besides, leaves provide shade and shelter to the stem and root

Flower:

Flowers are the blossoms of a plant. They are found everywhere. Many of the flowers are brilliantly colored and have a sweet smell.Some flowers blossom during day and some only at night. All flowers have the same function, i.e. to reproduce the species. A flower lives for a short time, and then it change into a fruit.
