Document Summary

Objectives of module: recognize the evolution of organelles through endosymbiosis identify the benefits of compartmentalization describe the important roles played by chloroplasts and mitochondria. Explain why carbohydrates are the primary source of energy in our bodies. Unit 1: eukaryotes and prokaryotes life was unicellular as oxygen was absent from oceans and atmosphere photosynthetic cells, specifically creatures that could create oxygen, opened up diversity evolved in proterozoic eon. Prokaryotic cells: unicellular organisms that lack a nucleus and have few to no organelles. Both have external membrane that separates inside and outside of cell. Mitochondria: convert the energy from food we eat into energy that powers. Share a common ancestor most cellular functions in our bodies. Photosynthesis: a process used in plant cells and other organisms to convert light energy into chemical energy. Chemical energy is stored in the bonds of carbohydrate molecules thylakoids: flattened and stacked membranes grana: stacks organized into piles.
