KSU Bio 198 Exam 6 Questions and Answers Already Passed 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. C4 In the ______ photosynthetic pathway, carbon dioxide is fixed by RUBISCO into sugars via the Calvin Cycle (just like in C4). C3 The _____ photosynthetic pathway separates light-dependent reactions and uses carbon dioxide and...

Gymnosperms (conifers) Seeds not enclosed in ripened ovary. Angiosperms (Flowering plants) Seeds are enclosed in a ripened ovary/fruit. 7 characteristics of seed plants 1. Megaphyllous leaves (branched veins w/ leaf trace gaps) 2. Heterospory [advanced] (production of spores of two different sizes and sexes) 3. Eusporangiate 4. Xylem and phloem 5. Dominant and independent sporophyte 6. Gametophyte is dependent on the sporophyte for nutrition 7. Reproduce by seeds Se...

charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: problems...
