KSU Bio 198 Exam 6 Practice Questions and Correct Answers

C4 The ______ photosynthetic pathway is where carbon dioxide is fixed by RUBISCO into sugars via the Calvin Cycle. It uses ATP, photorespiration is minimized, and it increases the rate of photosynthesis. C3 In the ______ photosynthetic pathway, carbon dioxide is fixed by RUBISCO into sugars via the Calvin Cycle (just like in C4). CAM The _____ photosynthetic pathway separates light-dependent reactions and uses carbon dioxide and the Calvin cycle temporarily. C3 The ______ photosynthetic pathway produces carbon fixation without using ATP and is ideal in a cool and moist habitat. C4 The ______ photosynthetic pathway has a large ATP cost because it fixed carbon twice. Carbon fixation is less efficient under cold conditions. It is ideal in hot environments (not cold). CAM The _______ photosynthetic pathway reduces the amount of fixed carbon, and the stomata only open at night. This reduces photorespiration and water loss. Best in hot and dry habitats. Green Algae __________ shares a recent common ancestor with plants and has a similar chloroplast structure to plants. Sporophyte A _______ is the plant generation that produces the spores (diploid). Gametophyte The plant generation that produces the gametes. Mitosis The process of _______ produces two diploid (2n) daughter cells, occurs in somatic cells, and is used for growth, cell replacement, etc. Meiosis ________ produces four haploid (n) daughter cells, occurs in sex cells, and is used to produce gametes for sexual reproduction. Desiccation ________ is a state of extreme dryness. Node A ______ is where leaves and buds occur. Internodes _______ are the spaces between nodes.
