Introduction to Plants

Plants are living things that grow, reproduce, and need sunlight, water, and air to survive. They play a vital role in our lives by producing oxygen, providing food, and supporting ecosystems.

Every plant is made up of different parts, and each part has a specific function. Learning these parts helps students understand how plants live and grow.

Main Parts of a Plant

A plant has five main parts:

• Roots
• Stem
• Leaves
• Flowers
• Fruits

Let’s explore each one in detail.

---

1. Roots

Roots grow underground and anchor the plant firmly in the soil.

Functions of Roots:

• Absorb water and minerals from the soil
• Hold the plant in place
• Store food in some plants (like carrots and radishes)

---

2. Stem

The stem is the main support structure of the plant and connects all parts.

Functions of the Stem:

• Supports leaves, flowers, and fruits
• Transports water and nutrients from roots to leaves
• Carries food from leaves to other parts

---

3. Leaves

Leaves are usually green and are attached to the stem.

Functions of Leaves:

• Make food using sunlight (photosynthesis)
• Exchange gases (oxygen and carbon dioxide)
• Help in transpiration (water loss)

---

4. Flowers

Flowers are the reproductive part of the plant.

Functions of Flowers:

• Help in reproduction
• Attract insects for pollination
• Develop into fruits after fertilization

---

5. Fruits

Fruits grow from flowers and contain seeds.

Functions of Fruits:

• Protect seeds
• Help in seed dispersal
• Provide food for animals and humans
