Part- A

Each question carries one mark

1. Which cells are destroyed in AIDS?

Ans: Lymphocytes

2. Which hormone is called as flight and fighting hormone? Why?

Ans:Adrenalin is called flight and fight harmone because it controls the endocrine glands in our body.

3. What is totipotency?

Ans: The ability of a plant to give rise to a new plant is called totipotency.

4. What is obesity?

Ans:It is a disease caused due to excess eating and energy intake.

Each question carries two marks.

5. What is systole and diastole?

Ans: The state when the heart is contracted is called as systole.In this phase blood is pumped into arteries. Diastole:The relaxed phase of the heart is called diastole.In this phase the blood vessels and chambers return to normal.

6. What is NADP?

Ans:The accepters which accept electrons is called as electron acceptor.eg Nicotinamine adenine dinucleoutide phosphate(NADP).

7. What do you understand by sexual dimorphism?

Ans:  The phenomenon of possession of only one sex by an organism is called is sexual dimorphism

8. Give an account of cretinism?

Ans:In a child when there is an insufficiency of thyroxine there is a retardation in its growth both mentally and physically.This is called as cretinism

Each question carries four marks.

9. How do you prove that oxygen is evolved during photosynthesis?

Aim: To prove that oxygen is evolved during photosynthesis.

Apparatus required: Beaker with water, test tube, funnel, Hydrilla twigs, glowing splinter.

Procedure: A beaker full of water is taken. A few branches of Hydrilla plant is taken and inserted into the narrow end of the funnel in such a way that the cut ends of Hydrilla plants must be in the narrow end of the funnel. The wide mouthed portion is kept in the beaker containing water. A test tube filled with water is carefully inverted over the narrow end of the funnel and the entire setup is left in the sunlight. After sometime, it is observed that gas bubbles come from the cut ends of the Hydrilla plants. These bubbles are collected at the end of test tube pushing the water into the beaker. After sufficient gas is collected, the test tube is taken out of the beaker by closing it with the thumb.

Observation : When a matchstick is introduced into the test tube it glows more
Result: The experiment proves that oxygen is evolved during photosynthesis.

10. Write a comparative account of photosynthesis and respiration.


1. Occurs only in plants and somephotosynthesis bacteria
2. Takes place in the presence ofsunlight only

3. A plant can survive without performing  photosynthesis for a few days

4. In plants, only few cells perform photosynthesis

5. It occurs in the chloroplast and is dependent on light.



1. Occurs in all living organisms.

2. Takes place throughout the day.

3. No organism can survive without respiration for few minutes

4. All living cells of an organism perform this process.

5. Aerobic respiration takes place in cytoplasm and mitochondria and is independent of light.


11. What is the role of Gibberellins in plant growth and development?

  • Gibberellins are responsible for  the stern elongation.
  • It also increases the leaf blade area. This is due to stimulation of cell elongation in both leaves and stem.
  • It leads to the formation of seedless fruits.
  • Gibberellins and auxins help in the cell elongation and leaf expansion.
  • These substances are also known to induce enzymes like protease and lipase etc., at the on set of seed germination and break the seed dormancy.

12. If one has taken the decision not to be infected with HIV, what are the  precautions he/she takes?

  • Ensuring during blood transfusion that the blood  is free from virus, it cannot be transmitted.
  • Use of disposable syringes or sterilized needles and seeking immediate treatment if found infected.

Question carries five marks:-
