An organism A which cannot move from one place to another makes a simple food B from the substances C and D available in the environment. Th is food is made in the presence of green coloured substance E present in organs F in the presence of light energy in a process called G. Some of the simple food B also gets converted into a complex food H for storage purposes. Th is food gives blue-black colour with iodine solution?
a) What is (i) organism A (ii) food B and food H?b) What are C and D?c) Name (i) green pigments E and organ F.d) What is the process G?
Answers
"A plant (A) cannot move prepares a simple form of food is called Glucose (B) from the substances called carbon dioxide (C) and water (D) available in the environment. This preparation is due to the presence of Chlorophyll (E), a green coloured substance, present in leaves (F) in the presence of light energy. This process is called as photosynthesis (G).
Glucose (B), a simple form of sugar, gets converted into starch (H), a complex food, for storage. The food is with iodine solution and looks in black colour.
(a) (i) A → plant; (ii) Food B → Glucose and food H → starch
(b) C → CO_2 and D → H_2O
(c) Green pigments E → Chlorophyll and Organ F → leaf
(d) Process G → Photosynthesis"
Answer:
(a) (i) Organism A is a green plant,
(ii) Food B is glucose and
(iii) food H is starch
(b) C is carbon dioxide and D is water
(c) (i) The green coloured substance E is chlorophyll and
(ii) organ F is a leaf
(d) The process G is photosynthesis
