KSU Bio 198 Exam 6 Questions And Answers (Updated And Verified) 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. - answerC4 In the ______ photosynthetic pathway, carbon dioxide is fixed by RUBISCO into sugars via the Calvin Cycle (just like in C4). - answerC3 The _____ photosynthetic pathway separates light-dependent reactions and uses carbon dioxide and the Calvin cycle temporarily. - answerCAM The ______ photosynthetic pathway produces carbon fixation without using ATP and is ideal in a cool and moist habitat. - answerC3 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). - answerC4 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. - answerCAM __________ shares a recent common ancestor with plants and has a similar chloroplast structure to plants. - answerGreen Algae A _______ is the plant generation that produces the spores (diploid). - answerSporophyte The plant generation that produces the gametes. - answerGametophyte The process of _______ produces two diploid (2n) daughter cells, occurs in somatic cells, and is used for growth, cell replacement, etc. - answerMitosis ________ produces four haploid (n) daughter cells, occurs in sex cells, and is used to produce gametes for sexual reproduction. - answerMeiosis ________ is a state of extreme dryness. - answerDesiccation A ______ is where leaves and buds occur. - answerNode _______ are the spaces between nodes. - answerInternodes ______ is the zone of actively dividing cells. - answerMeristem _______ tissue covers and protects surfaces. - answerDermal Xylem and phloem are two examples of ____________. - answerVascular Tissue _____ tissue provides storage and structural support for vascular tissue - answerGround ________ is the meiosis-produced pollen (male gametophyte). - answerStamen ______ is the meiosis-produced ovule (female gametophye). - answerPistle The process of _______ maintains ploidy levels. - answerMitosis The process of _________ reduces ploidy level. - answerMeiosis The fusion of _________ increases the ploidy level. - answergametes A _______ is a mature ovary specialized for the dispersal of seeds. - answerFruit _________ is the transfer of pollen to the stigma. - answerPollination _________ is the union of two gametes. - answerFertilization ________ is the uptake of water by a germinating seed. - answerImbibition __________ is the resumption of growth after seed dormancy is broken. - answerGermination The apical meristem is the ________ growth. - answerprimary The lateral meristem is __________ growth. - answersecondary ________ is a plant hormone that stimulates cell division and causes shoot elongation. - answerGibberellin ________ is dead at maturity and transports water and nutrients from roots to shoots. - answerXylem ________ is alive at maturity and transports photosynthates (sugars) & organic compounds. - answerPhloem ___________ is the loss of water from a leaf due to evaporation. - answerTranspiration ________ molecules are small, polar, cohesive, and adhesive. - answerWater Crossing a membrane from high to low concentration without expending energy is called ______ transport. - answerpassive
