KSU BIO 198 EXAM 6 QUESTIONS AND
ANSWERS 2025
, C4 - ANSWERThe ______ 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 - ANSWERIn the ______ photosynthetic pathway, carbon dioxide is fixed by
RUBISCO into sugars via the Calvin Cycle (just like in C4).
CAM - ANSWERThe _____ photosynthetic pathway separates light-dependent
reactions and uses carbon dioxide and the Calvin cycle temporarily.
C3 - ANSWERThe ______ photosynthetic pathway produces carbon fixation without
using ATP and is ideal in a cool and moist habitat.
C4 - ANSWERThe ______ 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 - ANSWERThe _______ 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 - ANSWER__________ shares a recent common ancestor with plants and
has a similar chloroplast structure to plants.
Sporophyte - ANSWERA _______ is the plant generation that produces the spores
(diploid).
Gametophyte - ANSWERThe plant generation that produces the gametes.
Mitosis - ANSWERThe process of _______ produces two diploid (2n) daughter cells,
occurs in somatic cells, and is used for growth, cell replacement, etc.
Meiosis - ANSWER________ produces four haploid (n) daughter cells, occurs in sex
cells, and is used to produce gametes for sexual reproduction.
Desiccation - ANSWER________ is a state of extreme dryness.
Node - ANSWERA ______ is where leaves and buds occur.
Internodes - ANSWER_______ are the spaces between nodes.
Meristem - ANSWER______ is the zone of actively dividing cells.
