Short Type Questions and Answers

Question 1. What are herbs?

Answer: The small plants with soft/tender, green, short stem are called herbs. Herbs hardly attain height more than 1.5 metres. Their stems are not woody and can be bent. A herb may or may not have branches, e.g., tomato, mint, paddy, etc.

Question 2. Write the differences between a shrub and a tree, based on the properties of the stem.

More branches arise from the base of stem.The branches arise from the stem.
The stem is hard and thinThe stem is hard, thick and woody.

Question 3. From the members of the various groups given below, find the odd one out.

  1. Coriander (dhania), mint (pudina), jamun, grass.
  2. Rose, mehndi, guava, morepankh.


  1. Jamun (Jamun is a tree while others are herbs).
  2. Guava (Guava is a tree while others are shrubs).

Question 4. What are climbers and creepers? Give some examples.

Answer: In some plants like grape vines, money plant, bean stalk, gourd plants, etc., the stem is so weak that it cannot hold it straight. They either stand up with some support or they just spread on the ground. In the first condition, the plants are called climbers and in second condition, they are called creepers or runners.

Question 7. Pitcher plant has green leaves which can prepare food by photosynthesis then why does it eat insects?

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

Question 8. What are weeds?

Answer: 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 9. What is a stem?

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

Question 10. Do you agree that stem is like a two way street?

Answer: Yes. Stem carries the water absorbed by the roots to the leaves and also the food prepared by the leaves to the roots

Question 11. What are the modification of stem?

Answer: Stem is modified to perform certain special functions:

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

Question 12. What are nodes and internodes?

Answer: 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.

Question 13. Define petiole and lamina.

Answer: The part of leaf which is attached to the stem is called petiole and the broad green part of the leaf is called lamina.

Question 14. What are veins?

Answer: There are some lines on the leaf called veins.

Question 15. What is midrib?

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

Question 16. Why are leaves generally green?

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

Question 17. What are the modifications seen in a pitcher plant?

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

Question 18. What are lateral roots?

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

Question 19. How do you identify the root system of a plant without pulling it out of soil?

Answer: 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 20. What is a fruit? How does it differ from a seed?

Answer: 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 21. Write the functions of sepals and petals.

Answer: 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 22. In what sequence does a plant bear?
Seed, Flower, Fruit.

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

Question 23. Write the names of reproductive parts of a flower.

Answer: The reproductive parts of a flower are:

  • Stamens
  • Pistil.

Question 24. What do you mean by a complete and an incomplete flower?

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

Long Type Questions and Answers

Question 1. Do all flowers have four separate whorls? Does any flower have more than four whorls? If so, write its name.

Answer: 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 2. Do all flowers have the same parts and are they arranged in the same way?

Answer: 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 3. Why roots are modified?

Answer: 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 4. Explain the difference between taproots and fibrous roots.


TaprootsFibrous 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.Found in the plants like grasses having parallel venation in leaves.

Question 5. What are the main functions of roots?

Answer: 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 6. 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 7. Explain the main functions of leaf.

Answer: 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.
