Nucleus

Ribosome

Mitochondrion

Golgi apparatus

الشرحMitochondria are the site of cellular respiration, producing ATP, which provides energy for the cell.

Energy storage

Catalyzing chemical reactions

Storing genetic information

Building cell walls

الشرحDNA contains the instructions needed for an organism to develop, survive, and reproduce.

Respiration

Photosynthesis

Fermentation

Transpiration

الشرحPhotosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from CO2 and water.

Atom

Organ

Cell

Tissue

الشرحThe cell is universally accepted as the fundamental unit of life.

Stomach

Large Intestine

Small Intestine

Liver

الشرحThe small intestine is the primary site for the absorption of nutrients into the bloodstream.

DNA only

RNA only

Both DNA and RNA

Protein only

الشرحInfluenza is an RNA virus, meaning it stores its genetic information in RNA rather than DNA.

Red Blood Cells

White Blood Cells

Platelets

Plasma

الشرحLeukocytes (white blood cells) are key components of the immune system.

Nucleus

Ribosome

Golgi Apparatus

Lysosome

الشرحRibosomes serve as the site of biological protein synthesis (translation).

Fructose

Glucose

Lactose

Sucrose

الشرحGlucose is the direct product of photosynthesis used by the plant for energy.

Cerebrum

Cerebellum

Brainstem

Thalamus

الشرحThe cerebellum is responsible for maintaining posture, balance, and voluntary muscle coordination.

Adenine

Guanine

Cytosine

Uracil

الشرحRNA uses Uracil to pair with Adenine, whereas DNA uses Thymine.

Pinocytosis

Phagocytosis

Exocytosis

Diffusion

الشرحPhagocytosis is the process of engulfing solid particles, often described as cell eating.

Protein synthesis

ATP production

Modifying and packaging proteins

DNA replication

الشرحThe Golgi apparatus acts like a post office, processing, sorting, and packaging proteins for secretion.

Frequently Asked Questions

Are these Biology MCQs free?

Yes. Every Biology MCQ on this page is free to practice, including the correct answer and explanation.

Do these include past-paper questions?

Yes — questions sourced from past papers are clearly marked with a "Past Paper" badge, alongside fresh practice questions.

Which exams do these Biology MCQs help with?

They are aimed at NASTP Institute of Information Technology and related Pakistani competitive exams that test Biology.

How should I practice subject-wise MCQs?

Attempt each question first, then reveal the answer and read the explanation. Short, focused sessions on one subject work better than long unstructured reading.
