Why Energy Is Essential for Life All living organisms require energy to survive and function. At the cellular level, energy is needed for processes such as growth, repair, movement, active transport, and cell division. Without a constant energy supply, cells would stop working, and life would not be possible. However, energy from sunlight or food cannot be used directly by cells. It must first be converted into a usable form. This conversion happens inside specialized organel

Introduction: Life on Earth, from the smallest bacteria to complex humans, is made up of cells . As an MYP student, understanding prokaryotic and eukaryotic cells  is one of the most important foundations of biology. This topic appears repeatedly in unit assessments, exams, and even in higher-level biology later on. In this blog, we’ll explore the differences between prokaryotic and eukaryotic cells  in a simple, student-friendly way—with examples, comparisons, real-life conn
