Provided with specimen E1 and E2 and required to carry out an experiment using the following procedures: (i) Cut the specimen E1 into two halves using scalpel/sharp knife. (ii) Put 2 drops of iodine solution on the surface of one half and leave it for five minutes then observe the colour changes (iii) Put two drop of Benedicts’ solution on the surface of another half. Leave it for five minutes then observe the colour change. (iv) Remove the outer cover from the specimen E1. (v) Rub the opened specimen E2 on a plain paper provided for some times then dry using an open flame and observe the changes. Questions (a) (i) What was the colour change after adding 2 drops of iodine solution on the surface of specimen E1? (b) (ii) Identify the food substances contained in specimen E1. (c) (iii) State the basis for the test which lead to the colour change. (d) Identify the enzymes which are responsible for digestion of the food substances identified from specimen E1 and state its end product of digestion. (e) What is the role of the food substance identified in part (a) (ii) in plant body? Give four points. (f) State two functions of the food substance contained in E2 to animal living in semiarid region.
