Document Summary
Refers to multiple small holes that exists in small groups. Sends out appendages for feeding and movement. Samples of diatoms (organism that build shelves) Every one of these species have different shapes. Protists are at the base of aquatic food chains. Fruits that uses energy from the sun primary producers. Bacteria is a huge part of the primary producers. The rest of the course deals with eukaryotes. Protists all e ukaryotes that are not green plants fungi and animals (iclicker) Give samples of characteristics that can distinguish the groups. Nuclear envelope originated from fold of the plasma membrane. Start with a cell that is structured: dna wall, cell membrane. Fold comes in from the cell wall. Archaea and bacteria: transcription and translation occur in same area. Eukaryotes: transcription and translation are separated: different forms of rna processing, gene expression could be better controlled. They are huge about as big as bacteria are: bigger than other organelles found in eukaryotes.
