Document Summary
1. meaning of endosymbiosis, cyanobacteria, lateral gene transfer a. b. c. Endosymbiosis: a mutually beneficial relationship in which one organism lives inside another. Cyanobacteria: microorganisms related to bacteria but capable of photosynthesis. Lateral gene transfer: transfer of genes between organisms by a manner other than reproduction. 2. origin of endomembrane system, nuclear membrane, er etc. Endomembrane system: the nuclear envelope and the endoplasmic reticulum: derived from infolding plasma membrane. Nuclear envelope separate genomic information from the rest of the cell, an advantage to tightly regulate transcription and replication of dna separate from the rest of the cell. Also separates transcription and translation in space giving a level of sophistication not seen in bacteria. Surface area is important if this is where electron transport takes place. With a lot of energy produced by multiple mitochondria there are many different processes that can take place.
