Endosymbiotic theory - Study guides, Class notes & Summaries

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...

Adaptation - A trait that helps an organism survive and reproduce adventitious roots - roots that arise above ground Alleles - Different forms of a gene allopatric speciation - the process of speciation that occurs with geographic isolation Aneuploidy - Abnormal number of chromosomes. Archea - have cell walls that, do not contain peptidoglycan assotative mating - an individual is more likely to mate with another that is similar in phenotype to itself autosomal inheritance - Inheritance o...

BIO 181 Exam 1Advantages of being multicellular - correct answer 1. labor distribution 2. longer lifespans Endosymbiotic Theory - correct answer theory that eukaryotic cells formed from a symbiosis among several different prokaryotic organisms Disadvantages of being multicellular - correct answer 1. need more food 2. if one organ fails the who organism can fail lack of biomolecular machines - correct answer limits a cell from becoming more complex Single-celled eukaryote organism - c...

IB Biology 1.5 Latest Version Already Graded A Endosymbiotic theory a theory that some eukaryotic organelles, such as mitochondria and chloroplasts, originated as free-living prokaryotes that invaded primitive eukaryotic cells. Allowed growth of smaller cells in a cytoplasm, through endocytosis, and the rapid replication they could persist indefinitely inside the large cells. It also states that mitochondria were once free living prokaryotic organisms that had developed the process ...

Prokaryote or Eukaryote in paramecium? - correct answer Compartments in the cell indicates that it's a eukaryote Property of water which makes it suitable for living? - correct answer Thermal Watson and Crick discovery about DNA - correct answer DNA is double helix What occurs in meiosis but not in mitosis? - correct answer Homologous chromosomes pair up Variation within a population - correct answer Fertilization and mutation properties of stem cells - correct answer ...

Bio 181 ASU Capco Exam 1 rated A+ already passed!Write a few sentences that explain what limits an individual cell from becoming more complex. Bimolecular machinery and division of labor The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: Kidney 00:57 01:39 In cell Biology what can limit the progress of science? Technology True or False: In you own multicellular body, cells with different ...

The association of ribosomes with _____ invaginations would support the _____ theory. correct answer: membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is? correct answer: filapodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. correct answer: true T/F In an extant prok...
