Botany and Plant Science Questions

Multiple choice

Which of the following is correctly matched?

  1. Axils - Leaf like structures

  2. Nodes - Place on the stem from which leaves and branches arise

  3. Internodes - Thin lines on the surface of leaves

  4. Apics - The point between two nodes

  5. Trunk - The modified roots to store food

B Correct answer
Explanation

Nodes are the points on the stem from which leaves and branches arise. The portion of the stem between two nodes is called an internode.  

Multiple choice

Which of the following statements about tubers is incorrect?

  1. Potato are tubers and they have distinct nodes and internodes.

  2. They are modified plant structures.

  3. These are enlarged to store nutrients.

  4. The tops or sides of the tuber produce shoots.

  5. They are used by plants to provide energy.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Potatoes are tubers. Tubers are almost spherical and do not have distinct nodes and internodes.

Multiple choice

What are the coiled structures of passion flower called?

  1. Bulbs

  2. Tubers

  3. Climbers

  4. Tendrils

  5. Creepers

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In climbers of the ground family and passion flower, some axillary buds develop into coiled structures called tendrils. These tendrils twine around some support like a post or a tree and help the plant for climbing. 

Multiple choice

Which of the following statements is incorrect?

  1. Petals are brightly coloured to attract birds and insects.

  2. Androecium is the male reproductive part of a flower.

  3. Petiole attach the leaves to the plant stem.

  4. Lamina is the protective covering of the bud.

  5. Veinlets are the thin lines on the leaves of a plant.

D Correct answer
Explanation

The wide, flat, green portion of the leaf is called the lamina or the leaf blade. 

Multiple choice

Which of the following statements about the roots of different plants is incorrect?

  1. Radish have modified roots to store food.

  2. Mango fruit contains food in its pulp.

  3. Rose plant stores large amount of food in its roots and looks swollen.

  4. Roots of Dahlia are modified to store food.

  5. Turnip looks swollen as it contains nutritious content.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Roots of a rose plant do not store food. Radish, carrot, and turnip have tap roots that are modified to store food. Dahlia and mango have fibrous roots, which are also modified to store food.

Multiple choice

Which of the following statements about permanent tissues is/are correct?

a. Plant permanent tissues are produced by meristematic tissues. b. They have a vacuolated cytoplasm. c. Permanent tissues are living tissues.

  1. a, b and c

  2. a and b

  3. a and c

  4. b and c

  5. b only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct answer as both statements a and b are correct. Plant permanent tissues are produced by meristematic tissues. They have a vacuolated cytoplasm.

Multiple choice

Which of the following meristematic tissues is/are matched correctly with their location?

a. Apical meristem - Tip of stem, root and branches b. Intercalary meristem - Vascular bundles called cambium c. Lateral meristem - Leaf base and leaf sheaths of monocots

  1. a, b and c

  2. a and b

  3. a only

  4. b only

  5. c only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct answer. Apical meristem tissues are present at the tip of stem, root and their branches.

Multiple choice

Which of the following is incorrect about sclerenchyma tissues?

  1. They act as a packing tissue and are found between other tissues.

  2. They are also known as fibres as they are elongated and thread-like.

  3. They are isodiametric without pointed ends.

  4. They are also known as stone cells.

  5. They give necessary strength, rigidity and flexibility to the plant body.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is incorrect as parenchyma tissues act as a packing tissue and are found between other tissues. Sclerenchyma tissues are the chief mechanical tissues of the plant.

Multiple choice

Which of the following tissues gives flexibility to plants?

  1. Apical

  2. Lateral

  3. Collenchyma

  4. Chlorenchyma

  5. Sclerenchyma
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The flexibility in plants is due to a permanent tissue called collenchyma. It allows easy bending in various parts of a plant without breaking. It also provides mechanical support to plants.
