BIOL 201 Chapter Notes - Chapter 1: Radiant Energy, Stromatolite, Chlorophyll
Document Summary
Chapter one: botany o o o o o o. A process where radiant energy from the sun is captured and used to form. A particle of light strikes chlorophyll which causes an electron to move. The excited electron initiates the flow of electrons that convert the to a higher level radiant energy to energy of sugar molecules. *** only plants, algae and some bacteria possess chlorophyll. Earliest known fossils consist of several kinds of small, relatively simple filamentous microorganisms that resemble bacteria. Fossilized microbial mats consisting of layers of filamentous and other microorganisms and trapped sediments. They still continue to form today in warm and shallow oceans o. Obtain energy through consumption of energy from external sources. Increase in photosynthetic organisms = more splitting of water = more. The increase in oxygen resulted in the creation of ozone which absorbs some of the uv rays.
