Pitcher plant eats insects to get nitrogenous compounds which it neither synthesizes nor can absorb from the soil.

Question 8.
What are weeds?

The unwanted plants that grow in the field with the main crops or in their surroundings are called weeds.
Weeds are the plants which are not grown by the farmers, e.g., grass.


Question 1.
What is a stem?

The part of the plant which generally grows above the ground level and bears leaves, flowers and fruits is called a stem.

Stem is modified to perform certain special functions:

  • Storage of food
  • Storage of water
  • Provide support
  • To make food
  • Multiplication or reproduction.

Question 5.
What are nodes and internodes?

Nodes: The point where the leaf arises on the stem. They are attached to the stem by a stalk.
Internodes: The portion of the stem between the two nodes.

There is a thick vein in the middle of the leaf called midrib.

Question 5.
What do you mean by

  1. leaf venation
  2. reticulate venation, and
  3. parallel venation?


  1. Leaf venation: The design made by veins in a leaf is called leaf venation.
  2. Reticulate venation: If the design is net-like on both sides of midrib, the venation is called reticulate venation.
  3. Parallel venation: In the leaves of grass, the veins are parallel to one another. This is called parallel venation.

Question 6.
Explain the main functions of leaf.

There are following two main functions of leaf:

  • Transpiration: The extra water comes out of the leaves through stomata in the form of vapour. This process is called transpiration.
  • Photosynthesis: The process by which leaves prepare their food from water and carbon dioxide in the presence of sunlight and a green-coloured substance i.e., chlorophyll is called photosynthesis.

Question 7.
Why are leaves generally green?

The green colour of leaves is because of the presence of chlorophyll.

Question 8.
What are the modifications seen in a pitcher plant?

In a pitcher plant, the lamina is modified into a pitcher and apex into its lid.

Question 9.

sheet in your notebook. Hold it in place as shown in the figure. Hold your pencil tip sideways and rub it on the portion of the paper having the leaf below it. Did you get an impression wuth some lines in it? Are they similar to those on the leaf?
Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 5
Yes, an impression with some lines in it is on the leaf. obtained. They are similar to those


Question 1.
What are lateral roots?

The smaller roots that grow on the main taproot are called lateral roots.

Question 2.
Why roots are modified?

Certain plants have modified roots to perform specific functions:

  • Storage roots, e.g., carrot, radish
  • Supporting roots, e.g., banyan, rubber
  • Climbing roots, e.g., money plant
  • Parasitic roots, e.g., dodder
  • Breathing roots, e.g., mangroves.

Question 3.
Explain the difference between taproots and fibrous roots with the help of diagrams.


Taproots Fibrous Roots
There is only one main and long root from which small roots grow. There is no main root. Many roots are grown together from the base of the stem in the form of bundle.
These roots go deep into the soil to more depth. These roots do not go very deep.
These roots cannot be separated from soil easily. These roots are easily separated from the soil.
Found in the plants like weeds having reticulate venation in leaves.Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 6 Found in the plants like grasses having parallel venation in leaves.Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 6(i)

Question 4.
What are the main functions of roots?

Main functions of roots are:

  • Roots absorb water and minerals from soil for the other parts of the plants.
  • Roots hold the plant firmly to the soil.
  • Some roots transform to store food, e.g., radish.
  • Roots of leguminous plants contain symbiotic bacteria which add the fertility of soil by fixing atmospheric nitrogen into nitrates.

Question 5.
Identify the structure seen in Fig. 7.22 and write three sentences about it.
Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 7
This is a fibrous root. It has the following features:

  • Roots are grown from the base of the stem.
  • These roots do not go very deep into the soil.
  • These roots are found in the plants having parallel venation in leaves, e.g., grasses.

Question 6.
How do you identify the root system of a plant without pulling it out of soil?

By looking at the venation of the leaves, we can identify the root system of a plants. Plants with leaves having parallel venation have fibrous root and leaves having reticulate venation have taproot.

Question 1.
What is a fruit? How does it differ from a seed?

After fertilization, the ovary of the flower gets stimulated by the action of seed and forms the fruits, like mango, orange, etc. Embryo surrounded by a hard wall is called the seed.

Question 2.
Write the functions of sepals and petals.

Functions of sepals: Sepals protect the inner parts of flower when it is a bud.
Function of petals: Petals attract the insects which are the agencies of pollination by colour and fragrance.

Question 3.
In what sequence does a plant bear?
Seed, Flower, Fruit.

A plant bears first flowers, then seeds and in the last fruits.

Question 4.
Write the names of reproductive parts of a flower.

The reproductive parts of a flower are:

  • Stamens
  • Pistil.

Question 5.
How will you cut an ovary in a proper way? Explain with the help of a sketch.

Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 9

Question 6.
Do all flowers have four separate whorls? Does any flower have more than four whorls? If so, write its name.

No. Some flowers have some additional whorls than others. Sometimes some of these whorls may even be absent. For example:

  • In Gudhal, an additional whorl of epicalyx is found.
  • In unisexual flowers, either stamen or pistil is absent.

Question 7.
Do all flowers have the same parts and are they arranged in the same way?

The flowers of different species of plants are different. The number of petals and sepals are different in different flowers. Some of the flowers have stamens and some flowers have only pistil, others have both. Sepals may be connected with petals in some cases; but in other cases, these may be separated. Thus the properties of flowers are different.

Question 8.
Name the male part of a flower. Draw its labelled diagram.

Male part of a flower is known as stamen. It has two parts-filament and anther. Anther contains pollen grains.

Question 9.
Draw a diagram of L.S. and T.S. of ovary to show ovules and locules.

Getting to Know Plants Class 6 Extra Questions Science Chapter 7 - 11

Question 10.
What do you mean by a complete and an incomplete flower?

The flower with all whorls, i.e., sepals, petals, stamen and carpel in it is a complete flower.
If any one of these is absent in a flower, it is called an incomplete flower.
