Cell Structure and Function Concepts

Cells are the fundamental building blocks of life, similar to Legos. All living organisms, from unicellular bacteria to multicellular humans, are composed of cells. Cells divide to form new cells, leading to the development of complex organisms. Animal and plant cells have distinct structures, with plant cells having additional components like cell walls and chloroplasts. Cells have various applications, including stem cell therapy and biodegradable plastics.
