State the requirements for seed germination and give the importance of each requirement. How will you demonstrate tropism in the shoot?

c) Requirements for seed germination: • Water: Activates enzymes, softens the seed coat, and transports dissolved nutrients to the embryo. • Oxygen: Essential for aerobic respiration, which provides energy for the embryo's growth. • Suitable temperature: Provides the optimal conditions for enzyme activity, which are crucial for metabolic processes during germination. d) To demonstrate tropism in the shoot (phototropism): Step 1: Obtain a healthy potted seedling and a cardboard box with a small opening cut into one side. Step 2: Place the potted seedling inside the box, ensuring the opening is the only source of light. Step 3: Position a light source (e.g., a lamp) outside the box, shining directly through the opening towards the seedling. Step 4: Leave the setup undisturbed for several days, providing regular watering. Step 5: Observe the direction of growth of the plant's shoot. Step 6: The shoot will be seen to bend and grow towards the light source, demonstrating phototropism, which is the growth response of a plant towards light.
