Question 1. What are the components of the transport system in human beings? What are the functions of these components?

Ans.The main components of the transport system in human beings are the heart, blood, and blood vessels. Heart pumps oxygenated blood throughout the body. It receives deoxygenated blood from the various body parts and sends this impure blood to the lungs for oxygenation. Blood helps in the transport of oxygen, nutrients, CO₂, and nitrogenous wastes. Blood vessels arteries and veins carry blood in all parts of body.

Question 2. Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds?

Ans. It is necessary in mammals and birds to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

Question 3. What are the components of the transport system in highly organised plants?

Ans. Highly organised plants have two important tissues for their transport system one is Xylem and other is Phloem. Xylem transports water and minerals from roots to aerial parts of the plant and Phloem transport food from leaves to other parts of the plants.

Question 4. How are water and minerals transported in plants?

Ans. The vascular tissue Xylem transports water and minerals in plants. Transpiration creates a suction pressure, as a result of which water is forced into the xylem cells of the roots. Then there is a steady movement of water from the root xylem to all the plant parts.

Question 5. How is food transported in plants?

Ans. Phloem transports food materials from the leaves to different parts of the plant. The transportation of food in phloem is achieved by utilizing energy from ATP which helps in creating osmotic pressure that transport food from the area of high concentration to low concentration.
