Cell Biology

Cell biology is a branch of biology that studies cells—their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division, and death. This is done both on a microscopic and molecular level.

Cells are the basic unit of life. They are the smallest units of an organism that can replicate independently, and they are often called the "building blocks of life". The study of cells is called cell biology.

Key Concepts

• Cell Theory: All living organisms are composed of cells. The cell is the basic unit of life.
• Types of Cells: Understanding the differences between prokaryotic and eukaryotic cells.
• Cell Structure and Function: Detailed study of cell organelles and their functions.
• Cell Membrane and Transport: How substances move in and out of cells.
• Cell Division: Processes like mitosis and meiosis that ensure genetic continuity.

Through the study of cell biology, we gain insights into how organisms grow, reproduce, and function. This knowledge is fundamental to the fields of molecular biology, biotechnology, medicine, and genetics.
