Biology 1

About this book

Biology 1 introduces the cell as the foundation of living systems. Learners investigate cell structures, the cell cycle, and the movement of substances across membranes to understand how organisms grow, reproduce, and maintain internal balance.

The study of photosynthesis and cellular respiration reveals how cells transform energy to sustain life. Connections with health, biotechnology, and environmental sustainability show why these microscopic processes matter on a much larger scale.
