Cell Processes: The Connection Between Life and Energy

The video introduces the unit on cell processes, emphasizing the interconnectedness of life. It covers photosynthesis, explaining how it converts carbon dioxide into glucose and produces oxygen. Cellular respiration is discussed, highlighting its role in energy production and homeostasis. The video also touches on cell division and replication, ensuring healthy cell function. Finally, it provides instructions for completing PDF activities related to the unit.
