MICB 201 Study Guide - Midterm Guide: Honduran Lempira, Planctomycetes, Retract
Document Summary
By the end of this chapter, a student should be able to correctly answer multiple choice questions designed to diagnose whether they can: define the cell shape terms: coccus, bacillus, spirillum, vibrio, hypha, mycelium and plasma. Mycelium is the vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae. Plasma: liquid: appreciate that some bacteria exhibit multicellularity and cell differentiation, explain what cell differentiation means and provide some examples. They have an enormous diversity with respect to size. Such as the bacteria t. namibiensus and e. fishelsoni which are bigger than eurkaryotic cells and are big enough to see without a microscope. On the other hand, they can be smaller than some viruses: explain the importance of cell sa:v relationships in nutrient acquisition and waste disposal. Bigger cells (bigger volume) means more food necessary and more waste excreted. Excretions and food consumption need to be done through the surface area, but volume increases faster than surface area.
