Question. Which organ acts as a pump in the circulatory system ?
Answer : The heart is a muscular organ that acts like a pump to continuously send blood throughout the body. The heart is at the centre of your circulatory system. This system consists of a network of blood vessels, such as arteries, veins, and capillaries.

Question. Veins and arteries carry blood. Which of these carry blood :
(a) away from the heart ?
(b) back to the heart ?
Answer : (a) Arteries.
(b) Veins.

Question. Where does blood absorb oxygen ?
Answer : Blood absorbs the oxygen in the small organelles also known as Alveoli (the singular name is Alveolus). These are present in the lungs. Carbon dioxide is dissolved in the blood, as it comes back into the capillaries back into the air sacs. Blood with fresh oxygen is distributed throughout the body.

Question. What stops blood from flowing backwards through the heart ?
Answer : Valves

Question. Name (i) largest artery, and (ii) largest vein, in our body.
Answer : (i) Aorta (ii) Vena cava

Question. What gaseous waste products are excreted by plants ?
Answer : Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. Oxygen released during photosynthesis is used for respiration while carbon dioxide released during respiration is used for photosynthesis.
Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems. The process of elimination of water is called transpiration.

Question. Where is the dirty blood in our body filtered ?
Answer : the kidneys

Question. Name the procedure used in the working of artificial kidney.
Answer : Hemodialysis

Question. From the following terms, choose one term which includes the other four : Plasma, Platelets, Blood, RBC, WBC
Answer : Blood

Question. What are the components of the transport system in highly organised plants ?
Answer : Transport system:
Xylem and phloem make up the transport system of organized plants.

i) Xylem: Xylem is a complex tissue.
Water and minerals are carried from the roots to the stem and leaves via the xylem.
It also gives the plant parts mechanical strength.
Tracheids, vessels, xylem fibers, and xylem parenchyma are the four types of elements that make up the xylem.

Tracheids: Tracheids are long, tube-like cells with lignified walls and a tapering end.
These are non-protoplasmic and dead.
Vessels: A vessel is a long cylindrical tube-like structure composed of multiple vessel parts with lignified walls and a big central cavity.
The vascular cells are also protoplasm-free.
The vessel's parts are joined by perforations in their common walls.

Question. Out of xylem and phloem, which one carries materials :
(a) upwards as well as downwards ?
(b) only upwards ?
Answer : (a) Phloem (b) Xylem 

Question. Name two liquids which help in the transport of substances in the human body.
Answer : Blood and Lymph

Question. What is the other name of main vein ?
Answer : Vena cava

Question. Name the conducting tissue of plants which is made of sieve tubes alongwith companion cells.
Answer : Phloem

Question. Name the conducting tissue in plants which is made of (a) living cells, and (b) dead cells.
Answer : (a) Phloem (b) Xylem

Question. State the term used for the transport of food from leaves to other parts of plant.
Answer : Translocation

Question. Which process in a plant is accomplished by utilising energy from ATP : transport of water and minerals or transport of food ?
Answer : Transport of food

Question. Name the two types of transport systems in the human beings.
Answer : Blood circulatory system and lymphatic system.

Question. Name a waste gas released by the plants (a) only during the day time, and (b) only during the night time.
Answer : (a) Oxygen (b) Carbon dioxide

Question. Name one animal having single circulation of blood and another having double circulation.
Answer : The animal which has the single circulation of blood: fish
The animal which has the double circulation of blood: human

(a) Some organisms store wastes in body parts.
(b) The value of systolic pressure is always lower than that of diastolic pressure.
Answer : (a) True (b) False

Question. Name the two parts of a plant through which its gaseous waste products are released into the air.
Answer : Lenticels and Stomata

Question. What happens to the glucose which enters the nephron tubule alongwith the filtrate ?
Answer : It is reabsorbed into the blood through blood capillaries surroundings the tubule
