BIOB 110 1st Edition Exam 2 Study Guide Lecture 7 1 Plants have 40 50 000 genes while humans only have 25 30 000 2 Plants essential are Carbon Hydrogen Oxygen Phosphorous Potassium Nitrogen Sulfur Calcium Iron Magnesium 3 Plant essential micronutrients are copper Boron Molybdenum and Manganese 4 4 major groups of organic molecules are a Carbohydrates b c d Lecture 8 5 storage proteins are low in lysine and tryptophan 6 storage proteins are low in methionine 7 Enzymes overcome the energy speed up a chemical process 8 All information is encoded in 4 Lecture 9 9 Viruses consist of a single strand of DNA or RNA and are surrounded by a coat True or False about prokaryotes 10 Have a nucleus 11 Are about 1 micron in diameter 12 Many have a flagellum that is used to speed up reactions 13 Reproduce by binary fission simple division and this is fast and efficient These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute 14 Bacteria can exchange DNA using conjugation use a tube to replicate vacuoles True or False about Thermophiles 15 Live in extremely cold environments 16 Have to deal with high temperatures high pressure and extreme pH values as well as little or no oxygen 17 Chaperonins an enzyme protect thermophiles from heat damage 18 Correct folding is irrelevant for enzyme function Lecture 10 19 Many prokaryotes will surround themselves in polysaccharide coating slime 20 Symbiosis fixation legumes do this 21 Pathogenesis diseases a relationship 22 Gene transfer between and they share genes 23 reduce N2 to NH3 ammonia 24 are caused by gene transfer between plants and bacteria and are an uncontrolled 25 When bacteria transfer genes with a plant hormone genes are replaced by a and a marker gene that allows only transformed cell to grow Lecture 11 26 Cell theory cells for the basic structure of all life and all cells arise from cells 27 tissues groups of that have similar structure and function 28 Organs groups of 29 Cell Wall provides and 30 Membrane phospholipid bilayer surround cytoplasm 31 Plasmodesmata plant channels 32 Nucleus contains information DNA 33 long protein fibers called microtubules that transport organelles and vesicle Lecture 12 34 Chemicals in an insects can trigger the plant to emit volatiles into the air to attract the of the insect that is ingesting the plant 35 Mycorrhizae symbiotic that infect plant roots and water and nutrient uptake Have dense networks of extending throughout the soil 36 Endomycorrhizae penetrate root cells and form haustoria reproduce by 37 live on surface of living roots reproduce by fruiting bodies
