Bryophytes Characteristics Vascular: no Seed Bearing: no Dominant Generation: gametophyte Examples/Phyla: liverwort, mosses, hornwort Special features: use spores, no seeds, need water for reproduction Paleozoic or Mesozoic: Paleozoic Ferns Characteristics Vascular: yes Seed Bearing: no Dominant Generation: sporophyte Examples/Phyla: monilophyta Special features: have sporangium Paleozoic or Mesozoic: Paleozoic Gymnosperms Characteristics Vascular: yes Seed Bearing: yes Dominant...

WSU Biology 106 Final Exam QUESTIONS AND CORRECT DETAILED ANSWERS Three basic plant organs - ANSWER- roots, stems, leaves roots - ANSWER- Absorbs water and minerals from the ground. Anchors plant in ground. Stems - ANSWER- Carry substances between roots and leaves; provide support for plant; holds leaves up to sunlight leaves - ANSWER- The main photosynthetic organs of vascular plants. Nodes - ANSWER- the points at which leaves are attached internodes - ANSWER- the stem segments bet...

Mycorrhizae correct answersSymbiotic organisms (aka symbionts) with plants that live on their roots, helping the plant gain nutrients Nerve net correct answersA nervous system that moves neural signals in all directions from the stimuli, found in invertebrates like hydra Malpighian tubules correct answersTubes in an insect that help with osmoregulation and excretion; they move waste into the main gut for removal. "Kidneys" of arthropods, they absorb ammonium and convert it into uric acid...

Independent variable - Value does not depend on another factor Dependent variable - Value depends on another factor Controlled variable - Kept the same throughout the experiment What are the two key tissues that allow plants to transport water or organic nutrients, respectively, over long distances? - Xylem - water and minerals from roots to shoots Phloem - transports sugars from photosynthesis to where they are needed In the root, plants need to take up more CO2 or O2? - More O2 Is the n...

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...
