Botany 224 9-28-10--Eukaryotes Prokaryotes have small chromosomes. Mitochondria have a genome. Centromeres pull chromosomes apart. Looking at Isogamy, Anisogamy, and Oogamy slide Eukaryotes have meiosis and mitosis. Sexual reproductions 2 elements. 1) Meiosis pulls chromosomes apart, 2) Mitosis don’t align chromosomes according to their homology… it pulls chromatids apart. Fertilization- two sex cells merging that produces a cell with two nuclei (heterokary) when the two nuclei merge (karyogamy) Flagella- they key to mobility The prototype of a eukaryote has two flagella Isogamy- haploid, same size, different mating types due to surface proteins Oogamy- femal has gotten so large that it can not move any more Key organelles in eukaryotes Cell wall, flagella on surface, nucleus has double membrane, ER, RER corresponds directly with nucleus, vesicles travel along actin filaments on cytoskeleton, salinity is

Unformatted text preview: based on cytoskeleton, the vacuole-tonoplast… in plant cells and fungi the vacuole is static and does not pump… it just fills up. Mitochondria-double membrane Examples of non-centrosome based cytoskeletons in the dinophyta Flagellum in inside the cell embedded in the cell membrane of eukaryotes, then they have toe cytoskeleton within that membrane. 5 supergroups 1. excavata 2. Chromalveolata 3. Rhizaria 4. Unikonta 5. Archae plastida Rhizaria are all amoeba like with pseudopodium (also T-lymphocytes) and looks like a sun with all of the extensions. Amoebozoa related to us because had only 1 flagellum (unikonta group) Archae plastida picked up cyanobacteris the first time. All pastid carriers due to the cyanobacteria living within them. Chromalveolata have reddish pigment....
