Test 4 Lecture 2 Photosynthesis- Powered by the Sun Light energy + CO₂ + H₂O→CH₂O + O₂ The sun is 4.5 billion years old and 93 million miles away from earth. What has the sun done for you Only provide you and all other life forms with energy Difference between plants and animals  Plants are autotrophs: This means that plants obtain water and other minerals from the soil and air around them to produce energy in the form of sugar and oxygen.  Animals are heterotrophs: Meaning that they derive their energy from other organisms like plants or other animals to collect their nourishment. Chloroplast History  Endosymbiotic Theory: The theory that eukaryotic cell organelles evolved from prokaryotic cells. Photosynthetic bacteria evolved into a chloroplast by infecting and living symbiotically with and early eukaryotic cell. A closer look at a leaf.  The labeled cross section of a leaf (today): Contained in the mesophyll is the chloroplast.  A labeled diagram of a chloroplast organelle:  A closer look at a chloroplast cross section from using a transmission electron microscope:  Transmission Electron Microscope: (TEM) Is a type of microscope that operates on the same basic principles as the typical micr
