Test for Excretion in Biology

Excretion is an important process in living organisms that helps in the removal of waste products and toxic substances from the body. In biology, there are various tests that can be conducted to study excretion and its related concepts. These tests allow students to understand the process of excretion and its significance in maintaining homeostasis. Here is a sample test for excretion in biology for Class 10 students:

Section A: Multiple Choice Questions

1. Which organ is responsible for excreting urine in humans?
a) Liver
b) Kidneys
c) Lungs
d) Stomach

2. What is the primary waste product excreted by the kidneys?
a) Urea
b) Carbon dioxide
c) Water
d) Glucose

3. Which of the following is not a part of the excretory system in humans?
a) Kidneys
b) Bladder
c) Lungs
d) Liver

4. Sweating is an example of excretion through which organ?
a) Kidneys
b) Lungs
c) Skin
d) Liver

5. Which of the following substances is not excreted by the kidneys?
a) Urea
b) Water
c) Glucose
d) Salts

Section B: Short Answer Questions

1. Explain the process of filtration in the kidneys.
2. Differentiate between excretion and egestion.
3. What is the role of the liver in excretion?
4. How does the respiratory system contribute to excretion?
5. Describe the role of sweat glands in excretion.

Section C: Diagram-based Questions

1. Label the parts of the urinary system.
2. Draw and label the structure of a nephron.
3. Illustrate the process of urine formation in the kidneys.

Section D: Application-based Questions

1. Explain how excessive alcohol consumption can affect the excretory system.
2. Discuss the impact of dehydration on excretion.
3. How does the excretory system maintain homeostasis in the body?
4. Investigate and propose a solution to reduce water pollution caused by industrial waste.

By conducting this test, students will be able to assess their understanding of excretion in biology. It covers various aspects such as the organs involved, waste products excreted, and the processes of excretion. Additionally, the short answer and application-based questions help evaluate the students' critical thinking and problem-solving skills.

Remember, it is important to answer the questions in detail and within the given word limit to provide a comprehensive understanding of the topic.
