Chloroplasts and Photosynthesis Concepts

Mr. Andersen explains the role of chloroplasts in photosynthesis, detailing their structure and function. He describes how chloroplasts convert sunlight into energy, the process of photosynthesis, and the Calvin cycle. The video also covers the evolutionary origin of chloroplasts, highlighting their similarities to cyanobacteria and the concept of endosymbiosis.
