Cell Biology Concepts and Processes

This video tutorial reviews key biology concepts for a state assessment, focusing on cells. It covers cell types, structures, and functions, including prokaryotic and eukaryotic cells. The session explains cell membrane dynamics, transport mechanisms, and homeostasis. It also discusses macromolecules, their energy roles, and processes like photosynthesis and cellular respiration. Finally, it details cell division through mitosis and meiosis, emphasizing genetic continuity.
