Document Summary

As we continue with theme 1 for biology 1a03, the structure of a cell, in module 2, we will focus on organelles and energy acquisition. The learning objectives for you in this module are to: 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. Life as we know it, began approximately 4 billion years ago. Life on earth was almost exclusively unicellular for most of earth"s history and oxygen was virtually absent from the oceans and atmosphere. This was a very harsh and inhospitable environment. The appearance of the first photosynthetic cells, specifically creatures that could create oxygen, opened up the flood gates of diversity that has lead to the vast array of organisms we see today.
