Structure and functions explain how biological components are organized and how each part performs specific roles, ensuring coordination, efficiency, and survival. Proper structure supports function, while functional demands influence structure, together maintaining growth, metabolism, regulation, reproduction, adaptation, and overall stability in living organisms through integrated systems and continuous interactions internally.
Cell is the basic structural and functional unit of life, carrying out metabolism, growth, reproduction, and maintaining all living processes.
Biomolecules are organic compounds like carbohydrates, proteins, lipids, and nucleic acids essential for structure, energy, regulation and life processes.
Cell cycle and cell division describe phases of cell growth, DNA replication, and division, producing new cells essential for growth, repair, and reproduction.
