Explain the structure and function relationships between chloroplasts and mitochondria
Chloroplast converts sunlight into energy, and mitochondria break this energy into cell-friendly ‘food’. Chloroplasts are harvesters, mitochondria are utilizers.
Relate structural and functional evidence in chloroplasts and mitochondria to the endosymbiotic theory of their origins.
Structural Evidence: Both have their own DNA, and have a double membrane
Functional Evidence: They can move on their own without instruction from the nucleus, and also divide on their own without instruction.
Conclusion: These organelles were once prokaryotic cells that were engulfed by a eukaryote. The eukaryote decided to utilise their functions to help itself and let them be.
To learn more about these two topics, watch this video that has an strange robotic-male voice over. Truly though, this is a very informational video.
