    (c) Can you think of one more function of roots apart from the ones discussed in the above questions?
    
    Solution:
    (a) Pot 1 will have a healthy plant because it contains roots. They help to absorb water and minerals from the soil. These are needed for the manufacture of food by the plant leaves.
    
    (b) Plant in pot 2 can be easily pulled because it lacks roots. Roots anchor the plant to the soil. They fix the plant firmly in the soil which prevents the plant from being pulled out easily or blown away by the wind.
    
    (c) Two important functions of roots are listed in the above questions:
    • Roots anchor the plant to the soil.
    • Roots absorb water and minerals from the soil.
    In addition, roots also perform the following functions:
    • Roots help in holding the soil together.

    b) A straight tapering root grows vertically down into the soil and gives out branches on all the sides. The main root is called the tap root (B) and the smaller side roots are called lateral roots (A). A bunch of several, thin, fibre-like roots of similar size are called fibrous roots (C).
    c) Tap root system (B) – Carrot, Radish Fibrous root system (C) – Bamboo, Sugarcane
    d) Fibrous root system is seen in the wheat plant.
    
    Case-Based Questions
    
    
21. Ravi conducted an experiment in which he filled a glass with one-third of water. He added a drop of red ink into that glass and then stirred it for few minutes. He took a tender twig and made an oblique cut at the base of its stem and then put it into the water as shown in the figure.
    
    a) What will Ravi observe if this set up is left undisturbed overnight?
    (a) Shedding of leaves from the stem
    (b) Rise of the colour into the stems
    (c) Development of red coloured roots
    (d) Development of more branches at the stem
    
    b) When Ravi made a cut at the base of twig stem, he observed a drop of water collected at its end. What could be the reason for the appearance of this drop of water?
    (a) Conduction of water through the stem
    (b) Transpiration of water through the stem
    (c) Formation of dew due to water condensation
    (d) Absorption of water by the stem from the surroundings
    
    c) What can be concluded from the experiment performed by Ravi?
    (a) To show that roots carry water and minerals in plants
    (b) To show that stem carries water and minerals in plants
    (c) To show that leaves conduct water and minerals in plants
    (d) To show that plants can absorb coloured liquids
    
    a) Correct option: (b) Rise of the colour into the stems
    Solution: Stem carries water and minerals in plants. Hence, red coloured water will enter the twig and travel through the stem. The twig stem will appear red in colour.
    
    b) Correct option: (a) Conduction of water through the stem
    Solution: The stem of a plant has several tubes which carry water and dissolved minerals from roots to leaves and other plant parts. Hence, when a part of the stem is cut, we can observe water collected at its base.
    
    c) Correct option: (b) To show that stem carries water and minerals in plants
    Solution: Just as red ink travels upwards through the stem, the minerals dissolved in water also move upwards through the stem along with water.

    (c)Correct option: (d) Hibiscus
    Solution: Hibiscus shows reticulate venation like mango. Grass, bamboo, and maize show parallel venation in which the veins run parallel to each other in the leaf lamina.
    
    Assertion-Reasoning Questions
    
    Below questions consist of two statements – Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below:
