Cell Structure and Function

Cell Structure and Function is a Biology chapter on the official PMDC MDCAT 2026 syllabus, contributing roughly 6 MCQs to the 81-MCQ Biology section. Mastering the core concepts below typically secures the full chapter weightage.

Key Concepts

Plasma membrane (fluid mosaic)
Mitochondria & chloroplasts
Endoplasmic reticulum
Golgi apparatus
Ribosomes
Lysosomes & peroxisomes
Cytoskeleton
Nucleus & nucleolus

How Cell Structure and Function Is Tested

MDCAT questions on Cell Structure and Function are a mix of recall (definitions, classifications), application (predict outcomes, interpret diagrams), and basic numerical/analytical reasoning. PMDC papers from 2020–2025 emphasized the concepts above; older UHS papers (2008–2019) tested them too, with slight variations in question framing.
