Exploring Photosynthesis and Cellular Respiration

The video tutorial prepares students for a lab on photosynthesis and cellular respiration, emphasizing the interconnectedness of these processes. It explains how photosynthesis occurs in autotrophs and cellular respiration in eukaryotes, using a carbon dioxide indicator to measure rates. The lab involves using algae beads to observe changes in photosynthesis and respiration under different light conditions. Students will also practice using microscopes to observe algae, enhancing their understanding of these biological processes.
