👉 Apartment biology, or cellular biology, is the study of the structure and function of cells, which are the basic units of life. Cells contain genetic material (DNA) that directs all cellular activities, proteins that perform various functions, and organellesāspecialized structures like mitochondria for energy production and the nucleus for storing genetic information. These components work together in a highly organized manner to maintain cell health, respond to environmental changes, and carry out essential processes such as metabolism, growth, and division. Understanding apartment biology is crucial for comprehending how multicellular organisms function, from the simplest single-celled organisms to complex humans, as cells communicate and coordinate their activities to sustain life.
