Further investigation showed that the victim had spent the past evening at a party with friends, around a campfire using the same wood. It was determined that this wood had been supplied by one of the people attending that campfire, and that more such wood was found stacked at his home place. Ultimately, scientists called __________________ were able to match the crime scene wood and the wood at the suspect’s home as being from the same tree. A. Palynologists B. Dendrochronologists C. Paleobotanists D. Foresters 8) All living organisms will eventually die of old age, if they don’t die of something else first. One hypothesized cause of death via old age is that the mitochondria accumulate mutations in their DNA and stop working. What will be a direct result of the mitochondria not working? A. The organism will be unable to make any proteins. B. The organism will be unable to make glucose. C. The organism will be unable to maintain homeostasis. D. The organism will be unable to make ATP. E. The organism will be unable to perceive the environment. 9) For you mushroom enthusiasts out there: Some mushrooms produce toxins like N-glycosylases that prevent a cell from linking monomers together to make a protein. This is how they defend against both animals and plants. Which part of the cell is affected by these toxins? A. Mitochondria B. Ribosomes C. Vacuole D. Nucleus 10) Michael is low in Vitamin B6, which helps maintain a healthy immune system. His doctors tell him he should eat dark leafy greens, bananas, cantaloupe, or oranges daily to keep up his levels of Vitamin B6 because the body can’t store it. What type of vitamin is Vitamin B6? A. Trace B. Water-soluble C. Essential D. Quantity E. Fat-soluble 11) In biology, when something is organic it means … A. It contains carbon. B. It is healthy. C. It is found in nature. D. It does not contain pesticides or herbicides. E. All of the above Consider the information below and use it to answer the next two questions: Scientists have broken an enzyme called AMSH3 in Arabidopsis thaliana plants. Without this enzyme the plant cells are unable to store other compounds and grow. Source: Isono, et al. 2010. The Plant Cell 22(6). 12) What part of the cell normally uses AMSH3? A. Ribosomes B. Plasma membrane C. Nucleus D. Chloroplasts E. Vacuole 13) What type of organic molecule is AMSH3? A. Protein B. Nucleic acid C. Carbohydrate D. Lipid 14) All of the following are characteristics of life we discussed EXCEPT: A. Needs energy B. Maintains homeostasis C. Has genetic material and uses it to reproduce D. Has a metabolism E. Thinks 15) Which monomer has an important function in quick energy storage and exchange? A. Glycogen B. Nucleic acid C. ATP D. A steroid E. An enzyme 16) Which statement about vegetarian diets and proteins is TRUE?1 A. Plants are low in proteins; vegetarians should add protein powders to food to get enough protein. B. Vegetarians do not need to worry about protein; every plant food provides all the amino acids. C. Vegetarians can get their full protein & amino acid needs by eating a diversity of plant foods. D. Plants have the non-essential amino acids but cannot provide any of the essential amino acids; to get those vegetarians need to supplement with other protein sources, like dairy or eggs. 17) While studying for your Botany exam, you practiced with your application of concepts we have been discussing.

His friends claim he camped the entire time with them and must have disappeared after their return home. While camping, they lived off the land and used foods they harvested fresh themselves. On May 9 his remains were found just inside the mouth of a small cave. Because of the conditions in/near the cave, officials are having a hard time estimating his time of death and ask you to help. When they did an autopsy, they found he had eaten some fresh fruit just before death. One of the seeds germinated in his digestive track after his death and started to grow. The seedling has two small cotyledons and a pair of leaves. What species would the seedling have to be to indicate he died while camping with friends, and not after? Option Species Monocot or Fruiting time in Cyprus Time to first true dicot leaf/leaves A Grapes Dicot May 10-12 weeks B Wheat Monocot May ~9 days C Banana Monocot February and March 5 weeks-6 months D Grapefruit Dicot January - March ~3 weeks E Figs Dicot February and March ~8 weeks 25) Which of the following characteristics cannot be used to distinguish plant species from each other?43 A. Whether the cells have a vacuole or not B. Margins of the leaves C. Whether the stem has a waxy cuticle or not D. Vein pattern on the leaves E. Arrangement of leaves on the stem NEARLY DONE! HOW ABOUT A LITTLE COOL DOWN? 26) Which cell part produces glucose?6 A. Ribosome B. Mitochondria C. Nucleus D. Chloroplast 27) Gluten is a(n)… A. Carbohydrate B. Lipid C. Protein D. Vitamin E. Amino acid 28) What is the function of the nucleus?39 A. Cellular respiration B. Prevent toxicity C. Establish homeostasis D. Store information 29) Which category does cholesterol belong in?44 A.
