Some of the questions and their solutions from NCERT Solutions for Class 10: Life Processes, are as follows:
Q. Why is diffusion insufficient to meet the oxygen requirements of Multicellular organisms like humans?
Sol: The size of the multi cellular organism is very much large as compared to unicellular one. Diffusion is a passive mode of transport and can transfer gases up to a very small distance only. This mode will not be sufficient for multi cellular organism needs.
Q. What are outside raw materials used by an organism?
Sol: Minerals, water and gases like carbon dioxide and oxygen are the outside raw materials used by an organism.
Q. How is the small intestine designed to absorb digested food?
Sol. Small intestine is especially adapted for absorbing the digested food. The inner surface of the small intestine has millions of tiny finger like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area. This large surface area helps in the rapid absorption of digested food.
Q. What are the components of the transport system in highly organized plants?
Sol. The plant transport system in highly organized plants contains the following –
Xylem – To transport water and minerals from roots to the other parts of the plant
Phloem – To transport food and hormones from leaves to the other parts of the plant
Q. How is the amount of urine produced regulated?
Sol. The kidney has a mechanism to reabsorb water from the filtrate. This depends on how much water is left in the body and in the filtrate. The comparative concentration of the water gives a signal to the brain which then takes the required corrective action of either reabsorbing water or releasing it.
