MICR 2420 Study Guide - Midterm Guide: Pyrococcus, Citric Acid Cycle, Phototroph
Document Summary
Greatest range of size and shape of all 3 domains: many branches, many are microbes, tree based on ribosomal rna or rrna. Animals and fungi are closely related relatives of fungi to study functions of animals and plant cells. Land plants and algae are closely related viridiplantae is land plants and algae, all are heterotrophs and move by pseudopodia (shapeless blobs: keep bacteria in control, some are parasitic. Who are the protozoa: combination of 3 free-living parasitic groups, described by the nature of cell wall and motility and feeding, excavata lack an obvious mitochondria. Differentiation of multicellular forms: many clades and phyla, all have intracellular organelles, mutlicellular forms in most, some have sexual/asexual or asexual reproduction. Animals, true fungi, microsporida, choanoflagellates, fit in one clade opisthokonta. Knowing the closest relative has its uses: we can use those organisms as models to answer key questions, we can define differences more clearly & exploit the knowledge to .
