Answers
Answer:
Excellent Questions.
Q1. How do you destarch a plan?
Ans. Destarching occurs when part of a plant is "deprived of starch, as by translocation". It is also the process of eliminating starch reserves in a plant for experiments concerning photosynthesis. This is done by leaving the plant(s) in a dark place for a long period of time.
Q2. What is the name of the reagent taken in the bottle and why?
Ans. Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.
Q3. Which part of the leaf turn bluish black?
Ans. The part of leaf that contains starch will turn blue black.
The photosynthesis occurs in the leaves during the day when the chlorophyll pigment absorbs the light energy from the sun to produce food in the form of carbohydrate.
Q4. Why was the plant kept in dark and then in sunlight?
Ans. If the plant would be in the sunlight it would simply produce more starch and then it would store it in it's leaves or other parts. If the plant is kept in the dark room then simply the plant would stop producing the glucose and the it would use up all the starch in it and the plant would become starch less.
