In the photosynthesis experiment, you exposed two syringes to light: one containing white leaf disks and one containing green leaf disks. State a null hypothesis for that experiment. 3. What was the purpose of adding sodium bicarbonate solution to the syringe containing the leaf disks? 4. In the chromatography experiment, what was the purpose of adding the acetone solvent into the test tube and then dipping the paper containing the chlorophyll pigment into that solvent? 5. Circle the answer choices that correctly complete this statement: In the moss lifecycle, the dominant stage is the sporophyte / gametophyte and this stage is haploid / diploid. 6. Which of the following groups has/have vascular tissue? Circle all that apply. mosses ferns gymnosperms angiosperms 7. Explain one of the evolutionary advantages of having a dominant stage that is diploid rather than haploid. 8. What is the distinguishing/unique feature of angiosperms that sets it apart from all the other plant groups we have studied? 9. What is the evolutionary advantage of having the embryo (fertilized zygote) develop in a seed (as in gymnosperms) rather than in an exposed condition (as in ferns)? |
