Answer 1

1. Procedure to prove light is essential for photosynthesis:

• Take the potted plant and keep it in a dark place for 2-3 days so that the leaves get destarched.
• Attach light proof black paper strips on both sides of the leaf with the help of paper clips.
• Place the plant in sunlight for 3-4 hours.

2. Essential nutrients cannot be synthesized by the body, and must be obtained from food. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch).

3. Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration. Aerobic respiration releases more energy than anaerobic respiration.

Answer 2

Answer:

1️⃣Take a plant with destarched leaf. Leaf is partially covered with black paper on which a design is cut. Expose this plant to sunlight for few hours and perform a starch test with iodine solution.

2️⃣1 Ingestion: taking food through our mouth. ... 3 Absorption: the simple soluble food is absorbed by blood through diffusion. 4 Assimilation: cell absorbed food through blood for its growth and repair of the body. 5 Egestion: undigested food material is moved through the surface of the cell and through out.

3️⃣Aerobic respiration is a fixed metabolic reaction that takes place in the presence of oxygen, going on in a cellular to transform chemical energy into ATPs.
