If you are preparing for the RRB ALP exam, you simply cannot ignore General Science. In CBT 1, Science carries a massive 20 marks, and Biology plays a huge role with around 4 to 6 direct questions. Many technical students fear Biology, but the exam only asks basic 10th-level questions about the human body and daily life. These are easy, free marks! To make your preparation simple, we have provided exam-level Biology questions with detailed solutions below. Practicing these, along with attempting our free topic tests, will definitely help you master this subject easily and quickly.
What to Study in Biology for RRB ALP?
You do not need to read thick medical books to pass this section. The exam only wants to check your basic general knowledge about living things. You can divide the whole syllabus into four simple parts:
- Human Body & Health: This is the most important part. Read about basic organs like the heart, brain, and kidneys. Also, memorize the Vitamin chart—which vitamin causes which disease (like Vitamin C causes Scurvy).
- Diseases and Causes: Railway exams love this topic. Just make a simple list of diseases caused by viruses (like Dengue, Polio), bacteria (like TB, Cholera), and mosquitoes (like Malaria).
- Plant Kingdom: You do not need to learn tough plant names. Just read about photosynthesis (how plants make food) and how plants transport water (Xylem) and food (Phloem).
- Basic Cell Structure: Read very basic facts about a cell. For example, what is the powerhouse of the cell, and what is the suicide bag of the cell?
If you just focus on these basic topics, Biology will become a very high-scoring subject for you!
Important Biology Questions for RRB ALP
If you are serious about scoring good marks, practicing real exam-level questions is a must. Grab a pen and a rough sheet. Try to solve these top-repeated biology questions and check the logic below. Along with that, we have provided a PDF that consists of more exam-level questions that you can download for free.
Q1. Which part of the cell is known as the “Powerhouse of the Cell”?
(A) Nucleus
(B) Ribosome
(C) Mitochondria
(D) Lysosome
Answer: (C) Mitochondria
Explanation:
Mitochondria produce energy for the cell to function properly, similar to how a powerhouse generates electricity for a city.
Q2. The disease “Scurvy” is caused by the deficiency of which vitamin?
(A) Vitamin A
(B) Vitamin B
(C) Vitamin C
(D) Vitamin D
Answer: (C) Vitamin C
Explanation:
A deficiency of Vitamin C causes scurvy, which leads to symptoms such as bleeding gums and weakness. Citrus fruits like lemon and amla are rich sources of Vitamin C.
Q3. Which blood group is known as the “Universal Donor”?
(A) AB Positive
(B) O Negative
(C) A Positive
(D) B Negative
Answer: (B) O Negative
Explanation:
O Negative blood does not contain A, B, or Rh antigens, allowing it to be safely transfused to people of any blood group in emergencies.
Q4. Which plant tissue transports water from roots to leaves?
(A) Phloem
(B) Stomata
(C) Xylem
(D) Cortex
Answer: (C) Xylem
Explanation:
Xylem transports water and minerals from roots to other parts of the plant. Phloem transports food produced in the leaves.
Q5. Which gland in the human body is called the “Master Gland”?
(A) Thyroid Gland
(B) Pituitary Gland
(C) Adrenal Gland
(D) Pancreas
Answer: (B) Pituitary Gland
Explanation:
The pituitary gland controls the activity of many other endocrine glands and is therefore called the master gland.
Q6. Malaria is caused by which of the following?
(A) Virus
(B) Bacteria
(C) Fungi
(D) Protozoa
Answer: (D) Protozoa
Explanation:
Malaria is caused by a protozoan parasite called Plasmodium. It spreads through the bite of infected female Anopheles mosquitoes.
Q7. What is the longest and strongest bone in the human body?
(A) Tibia
(B) Radius
(C) Femur
(D) Fibula
Answer: (C) Femur
Explanation:
The femur, also known as the thigh bone, is the longest, strongest, and heaviest bone in the human body.
Q8. Which instrument is used to measure blood pressure?
(A) Stethoscope
(B) Sphygmomanometer
(C) Thermometer
(D) Barometer
Answer: (B) Sphygmomanometer
Explanation:
A sphygmomanometer is the device used to measure blood pressure using an inflatable cuff and pressure gauge.
Q9. Which gas is released by plants during photosynthesis?
(A) Carbon dioxide
(B) Nitrogen
(C) Oxygen
(D) Hydrogen
Answer: (C) Oxygen
Explanation:
During photosynthesis, plants absorb carbon dioxide and release oxygen as a byproduct.
Q10. Which organ filters blood and produces urine in the human body?
(A) Liver
(B) Kidney
(C) Heart
(D) Lungs
Answer: (B) Kidney
Explanation:
The kidneys filter waste and excess water from the blood, producing urine to remove these wastes from the body.
5 Simple Tips to Prepare for Biology for RRB ALP
You do not have the time to read thick medical books, and honestly, you do not need to. Here are 5 smart and easy tips to cover this topic quickly:
- Memorize the Vitamin and Disease Chart: Railway exams love asking about vitamins and diseases. Make a small chart of Vitamins (A, B, C, D, E, K), their chemical names, and the diseases caused by their lack. Stick it on your wall.
- Understand “Virus vs Bacteria”: Many students mix up diseases. Make a simple list of 5 viral diseases (like Polio, Dengue) and 5 bacterial diseases (like Cholera, TB).
- Focus on the Human Body: Stop reading about tough animal species. 80% of the questions will be about your own body. Learn simple things about digestion, breathing, and blood.
- Use 10th Standard Books: Do not buy heavy competitive exam books for Science. A simple 10th-level NCERT summary book or Lucent’s GK is more than enough for this exam.
- Practice Previous Year Papers: Railway exam questions mostly match with each other’s science questions. Solve the previous year’s biology questions of RRB Group D, NTPC, and ALP. You will see the exact same questions repeating!
