* They are the basic building blocks of an organism. Every living thing is made up of cells.
* They have a specific structure and function. Different types of cells perform specialized tasks (e.g., muscle cells contract, nerve cells transmit signals, skin cells protect the body).
* They contain the organism's genetic material (DNA). This DNA determines the characteristics of the organism.
* They are capable of growth and division. This allows the organism to grow and repair itself.
* They are surrounded by a cell membrane. This membrane controls what goes in and out of the cell.
* They contain organelles. These are specialized structures within the cell that perform specific functions (e.g., mitochondria for energy production, ribosomes for protein synthesis).
* They work together to form tissues, organs, and organ systems. This creates a complex, organized body.
* They have a limited lifespan. Cells have a natural lifespan, and they eventually die and are replaced by new cells.
* They can be affected by environmental factors. Things like toxins, radiation, and disease can harm cells.
