Worksheet 7: Class 6 Science - Getting to Know Plants

Welcome! In this worksheet, we'll explore the amazing world of plants. We will learn about the different types of plants and the functions of their various parts. Let's get to know the plants around us!

Types of Plants and Their Parts

Plants are classified into three main categories based on their stems and branches:

• Herbs: These are small plants with soft, green, and tender stems. They usually have few branches or no branches at all. Examples include spinach and mint.
• Shrubs: These plants are medium-sized with hard, woody stems that branch out near the base. The stem is not very thick. Examples include lemon and rose plants.
• Trees: These are tall and big plants with hard, thick, woody stems (trunks) and branches high above the ground. Examples include mango and banyan trees.

Each part of a plant has a specific job:

• Stem: The stem transports water and minerals from the roots to the leaves and food from the leaves to other parts of the plant.
• Leaf: Leaves are the food factories of the plant. They make food through a process called **photosynthesis**. Leaves have a main vein called the **midrib** and many smaller side veins.
• Root: The roots anchor the plant firmly to the soil and absorb water and minerals. There are two main types of root systems: a **taproot** (a single main root) and a **fibrous root** (a cluster of similar roots).
• Flower: Flowers are the reproductive part of the plant.

Practice Questions

1. Fill in the blank: Plants with soft, green, and tender stems are called _____.

Herbs

2. True or False: The main function of a stem is to absorb water from the soil.

False. The main function of a stem is to transport water and food. The roots absorb water from the soil.

3. Match the plant to its type:

(a) Spinach (i) Tree

(b) Rose (ii) Shrub

(c) Mango (iii) Herb

a - iii, b - ii, c - i

4. What is photosynthesis?

Photosynthesis is the process by which green leaves make food for the plant using carbon dioxide, water, and sunlight.

5. Fill in the blank: The main root from which other smaller roots grow is called a _____.

Taproot

6. Why are leaves called the "food factories" of a plant?

Leaves are called the food factories because they make food for the entire plant through the process of photosynthesis.

7. Name the two main functions of roots.

Roots anchor the plant to the soil and absorb water and minerals from the soil.

8. What is the difference between a shrub and a tree?

A **shrub** is a medium-sized plant with a hard, woody stem that branches out near the base. A **tree** is a tall and big plant with a thick, woody stem (trunk) and branches high above the ground.
