1.	Q. Answer the following questions.1. Describe how protein is tested in food.2. How does taproot and fibrous root differ from each other? Give one-one example of each. 3. Identify the components present in the material based on the following result or conclusions.(a) Cut the raw potato and apply two to three drops on it - shows blue Back colour. (b) Wrap the ground nut seed in paper and crush it carefully ,oly patch can be seen on paper.
Answer» Answer: 1) l) The presence of protein is TESTED by the Biuret test for proteins. The Biurette reagent made of sodium hydroxide and copper (II) sulphate helps in determining the presence of protein in a sample 2) Taproot grows VERTICALLY downwards and thus reaches deep into the soil. The fibrous root grows horizontally in all directions and thus doesn't reach deep into the soil. The Taproot system anchors the plant more firmly than the fibrous root. Fibrous root system anchors less EFFICIENT than taproot 3) a) If we put a drop of iodine on a cut potato, we can SEE that that the colour changes to blue-black. This indicates the presence of starch. ... we can say that it contains starch. b) sorry!!! no idea

Answer:

1) l) The presence of protein is TESTED by the Biuret test for proteins. The Biurette reagent made of sodium hydroxide and copper

(II) sulphate helps in determining the presence of protein in a sample

2) Taproot grows VERTICALLY downwards and thus reaches deep into the soil. The fibrous root grows horizontally in all directions and thus doesn't reach deep into the soil. The Taproot system anchors the plant more firmly than the fibrous root. Fibrous root system anchors less EFFICIENT than taproot

a) If we put a drop of iodine on a cut potato, we can SEE that that the colour changes to blue-black. This indicates the presence of starch. ... we can say that it contains starch.

b) sorry!!! no idea
