Complete Biology Concept PYQs Important Questions For SSC & Railways: Biology plays a crucial role in the General Science section of SSC exams. Many questions asked in SSC, Railway, and other one-day competitive exams come from basic concepts such as cells, respiration, plant classification, vitamins, and human physiology.
Here, we will explore important Biology Questions for SSC and Railway exams along with explanations. These PYQs will help students understand frequently tested concepts and strengthen their exam preparation.
Below are some Important Biology Questions for SSC and Railway exams that frequently appear in competitive examinations.
Question:
Who discovered cells for the first time?
A. Antonie van Leeuwenhoek
B. Robert Hooke
C. Schleiden
D. Schwann
Answer: Robert Hooke
Explanation:
Robert Hooke discovered dead cells in cork in 1665. Later, Antonie van Leeuwenhoek (1674) observed living cells under a microscope.
Question:
Cells that contain nuclear material but do not have a nuclear membrane are called:
A. Eukaryotic cells
B. Prokaryotic cells
C. Animal cells
D. Plant cells
Answer: Prokaryotic cells
These cells have genetic material but lack a true nucleus because the nuclear membrane is absent.
Question:
Which organelle is known as the protein factory of the cell?
A. Ribosome
B. Lysosome
C. Mitochondria
D. Nucleus
Answer: Ribosome
Ribosomes synthesize proteins and are therefore known as the protein factories of the cell.
Question:
Which group of plants are called the amphibians of the plant kingdom?
A. Gymnosperms
B. Pteridophytes
C. Thallophyta
D. Bryophyta
Answer: Bryophyta
Bryophytes live on land but require water for reproduction, which is why they are called amphibians of the plant kingdom.
Question:
Breakdown of pyruvate into lactic acid and energy occurs during which process?
A. Aerobic respiration
B. Anaerobic respiration
C. Photosynthesis
D. Transpiration
Answer: Anaerobic respiration
When oxygen supply is low, pyruvate converts into lactic acid in muscle cells, producing a small amount of energy.
Question:
Which disease is caused by deficiency of Vitamin C?
A. Rickets
B. Pellagra
C. Beriberi
D. Scurvy
Answer: Scurvy
Vitamin C deficiency causes symptoms such as bleeding gums, weakness, and skin problems.
Question:
Which of the following are connective tissues?
Blood
Bone
Ligament
A. Only 1
B. 1 and 2
C. 1, 2 and 3
D. Only 3
Answer: 1, 2 and 3
Connective tissues connect different organs and structures in the body.
Question:
Which gland is known as the master gland of the endocrine system?
A. Thyroid gland
B. Pituitary gland
C. Pineal gland
D. Adrenal gland
Answer: Pituitary gland
The pituitary gland controls the secretion of other endocrine glands in the body.
Question:
Which of the following is a communicable disease?
A. Diabetes
B. Measles
C. Hypertension
D. Cancer
Answer: Measles
Measles spreads easily through respiratory droplets and is a highly contagious viral disease.
Question:
The male reproductive organ in a flower is called:
A. Pistil
B. Stamen
C. Ovule
D. Sepal
Answer: Stamen
The stamen produces pollen grains and represents the male reproductive part of a flower.
