Chapter 7 – Getting to Know Plants

There are different parts of a plant. Some of them are found above the soil while some are below the soil. The parts of the plants are stem, leaf, flower, roots, seed and roots. They are mentioned below:-

Stem

The main part of the plant is the stem. 

• The stem has various functions. 
•  It provides the plant with structural support.
•  It also helps in the transport of water, food and minerals. 
• The leaves, as well as the branches, arise from the stem.
• Stems can be of various types which include the bulb, tree and also thorns. Bulbs are fleshy like that of onion. A woody stem is found in a tree with the main trunk. Thorns are round and pointed like that in a hawthorn.

Leaf

Another most significant part of the plant is the leaf. A leaf is the plant organ which is above the ground. It performs functions of photosynthesis and exchange of carbon dioxide for oxygen. Being flat in structure, it can absorb maximum sunlight. 

• It performs one of the most important functions for plants. 
• Most leaves of the plants are generally green in colour. 
• They have different shapes as well as sizes of leaves.
• There are various parts of a leaf. 
• They are attached to the stem through the petiole. 
• The broad, as well as the green part of the leaf, is known as the lamina. 
• The veins are the midrib of the plant. 

Flower

A reproductive part of a plant is the flower. 

• The single function of a flower is that it serves the reproduction process. 
• The different parts of a plant are four in number. 
• The parts include the petals, the sepals, female style and the male stigma.

Root

Another part of the plant which is found under the soil is the root. The functions of the roots are:

• It gives support to the plant. 
• The root also receives the water as well as minerals.
• They also store the food for the plants.

Kinds of roots

There are broadly two kinds of roots which includes taproot as well as the fibrous root. 

• Taproots are those that are seen in trees and shrubs. 
• In herbs, the fibrous roots are found.

Examples of taproots are carrot and dandelions. 

Example of fibrous roots is grass.

Seed

The enclosed and the dormant embryo of a plant is the root. We get seeds in the fruits which when planted, we get a new plant.

Plants are primary food providers. They produce their own food. They have a unique system like the photosynthesis, which they follow to produce their own food through sunlight. They provide greenery around us. They are the basic lifeline which provides us with food and oxygen. They have medicinal values and also purify the air. So getting to know plants calls for measures to grow plants and conserve them as well.

1. What are plants for Class 6?

Ans: Plants provide food, and we breathe as they release oxygen into the air. They are primary food producers, and their various parts are the stem, leaf root, seed and flower.

Based on these features, most plants can be classified into three categories: herbs, shrubs and trees.

2. What are the parts of plants? 

Ans: The various parts of the plant are the stem, leaf root, seed and flower.

3. What are veins in plants Class 6? 

Ans: The small lines which are present on the leaf are known as its vein. They help to transport water as well as minerals throughout the leaf. The thick vein, which is in the middle of the leaf, is known as the midrib.

4. What are the 3 things we already know about plants? 

Ans: The three things that we know about plants are as follows:-

1. Plants produce their own food with the help of sunlight.
2. Plants are of three types: herbs, shrubs and trees.
3. Plants give out oxygen that we breathe.

5. What are the 7 things plants need to grow? 

Ans: Plants require sunlight, water, nutrients, air, the perfect temperature, time, and room to grow.

6. What are the 3 things we already know about plants or plant cells?

Ans: They are as follows:-

1. Plant cells are eukaryotic, that means they have a definite nucleus. 
2. Plant cells contain three different structures.
3. Plant cells are distinct from other eukaryotes, like the animal cells with a cell wall, plastids, and vacuoles.
