Multiple Choice Question

Question 1: The tube responsible for passing stored urine out of the body is known as

1. kidney
2. urinary bladder
3. ureter
4. urethra

Answer – (d) urethra.
Explanation: The human excretory system includes a pair of kidneys, ureters, a urinary bladder, a urethra, and a urinary opening. Urine travels from the kidneys through the ureters to the urinary bladder before being excreted through the urethra.

Question 2: These structures, resembling pipes and composed of specialized cells, facilitate substance transport and create a two-way flow in plants. Which term fits these characteristics?

1. Root hair
2. Vascular tissue
3. Xylem tissue
4. Phloem tissue

Answer – (d) Phloem tissue.
Explanation: Phloem tissue comprises specialized cells like sieve tubes that transport food bidirectionally in plants, allowing movement both upwards and downwards.

Question 3: The absorption of nutrients and exchange of respiratory gases between blood and tissues occur in

1. veins
2. capillaries
3. heart
4. arteries

Answer – (b) capillaries.
Explanation: Capillaries, with their thin walls, facilitate the exchange of gases and nutrients between blood and tissues by picking up wastes like carbon dioxide and transporting oxygen and digested food to body cells for cellular respiration.

Question 4: Which part of the human body lacks sweat glands?

1. Lips
2. Scalp
3. Palms
4. Armpits

Answer – (a) Lips.
Explanation: Lips do not have sweat glands, unlike areas like the scalp, armpits, and palms which do secrete sweat for temperature regulation.

Question 5: In tall trees, what force pulls water and minerals from the soil?

1. Gravitational force
2. Suction force
3. Transportation force
4. Conduction force

Answer – (b) Suction force.
Explanation: Root cells absorb water and minerals from the soil continuously. The transpiration process creates a suction force (transpiration pull) by evaporating water from leaf surfaces, aiding in upward water movement.

Question 6: Aquatic animals like fish excrete waste in gaseous form as

1. hydrogen
2. oxygen
3. nitrogen.
4. ammonia

Answer – (c) ammonia.
Explanation: Many aquatic animals excrete ammonia gas as waste, which easily dissolves in water. This process is known as ammonotelism.

Very Short Answer Type Questions:

Question 7: Why does blood flow in arteries in one direction despite lacking valves?

Explanation: Arterial blood flow is rapid due to high pressure and non-collapsible elastic walls that maintain a continuous one-directional flow without the need for valves.

Question 8: What unique feature of the human heart prevents mixing of oxygen-rich and carbon dioxide-rich blood?

Explanation: The human heart’s four-chambered structure with two atria and two ventricles separated by a muscular septum ensures complete segregation of oxygen-rich and carbon dioxide-rich blood to prevent mixing.

Question 9: Identify the organ located in the chest cavity with its lower tip slightly tilted towards the left.

Answer: Heart.
Explanation: The heart is situated in the chest cavity with its lower tip slightly inclined towards the left side.

NCERT Exemplar Chapter 11 Transportation in Animals and Plants FAQs

What are the functions of transpiration in Plants discussed in Chapter 11 of NCERT Exemplar Solutions for Class 7 Science?

The functions of transpiration in Plants discussed in Chapter 11 of NCERT Exemplar Solutions for Class 7 Science are – 1. The temperature is lowered in plants which prevents heat injury. 2. Transpiration pull occurs where the rainwater is stored in higher plants. 3. It also causes loss of water which is absorbed by plants. Students can understand this concept in a better way by referring to the solutions available at INFINITY LEARN. Both the chapter-wise and exercise-wise format of solutions are present here which can be used by the students as per their needs.

What is the function of the heart explained in Chapter 11 of NCERT Exemplar Solutions for Class 7 Science?

The heart is an organ of the human body which acts as a pump to transport blood and other substances. There are four chambers where the upper two chambers are called the atria and the lower two chambers are called the ventricles. There is a partition between them which helps to avoid mixing up of blood containing oxygen and carbon dioxide. Blood flow occurs from the heart to the lungs and back to the heart from where it is supplied to all the parts of the body. This concept is explained along with diagrams to improve visual learning among students which is important for the exam.

What are the components of blood explained in Chapter 11 of NCERT Exemplar Solutions for Class 7 Science?

The components of blood explained in Chapter 11 of NCERT Exemplar Solutions for Class 7 Science are – 1. Red Blood Cells (RBC) 2. White Blood Cells (WBC) 3. Platelets 4. Plasma
