3. Very poor muscle development is seen.
4. Swollen legs, fluffy face, difficult to eat, diarrhoea, dry skin are the symptom of this disease.

Q. Plants photosynthesize during day time and respire during the night. Do you agree with this statement? Why?
A. 1. No, I do not agree with this statement.
2. Plants photosynthesize during day time only.
3. Plants respire during the day time as well as night time also.

Q. Imagine what happens if diaphragm is not there in the body?
A. 1. During inhalation the diaphragm contracts and flattens increasing the volume of chest cavity.
2. During exhalation it relaxes decreasing the volume of chest cavity.
3. If diaphragm is not there in the body there will be no breathing movements.
4. So breathing stops.

Q. Why does the rate of breathing increases while uphill at a normal pace in the mountains? Give reasons.
A. 1. While uphill more energy is required to compensate required energy, the rate of respiration increases.
2. At higher levels the percentage of oxygen decreases. So to get more oxygen the rate of respiration increases.
3. Due to this, the rate of respiration increases while uphill at a normal pace in the mountains.

Q. What is root pressure? How can you say that it is useful to the plants?
A. 1. Root pressure in osmatic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.
2. Root pressure develops due to the absorption of water by roots and pushes the water upwards by few meters and is enough to supply water to leaves in small plants and small trees.
3. This water is utilized for photosynthesis and other biological processes. The rest of the water will be released into atmosphere
through transpiration.
