17. Which part of the microscope would be adjusted to sharpen the image of a specimen at high magnification?






18. What pigment absorbs energy and can emit an electron in photosynthesis?






19. Seeds are not protected by fruit and they do not have flowers - do not have shell around seeds - reproduce by releasing pollen into the air to make available to the ovule in the megaspores - causing fertilization






20. Bugs crawl into 'pitchers' - tiny hairs keep them from getting out - plant breaks down enzymes - and uses nitrogen. lives in places where nitrogen is limited.






21. What best describes a dry fruit which opens at maturity?






22. NO vascular tissue - NO roots - have modified photosynthetic tissue to help it absorb carbon dioxide without losing too much water - can survive in variety of environments - seedless - and commonly seen as mosses - hornworts - and liverworts.






23. What is considered part of the protoplast?






24. What would be a way of keeping a short-day plant from blooming?






25. What are homologous chromosomes?






26. What type of RNA has an anticodon?






27. Cladifils- modified stems that look like leaves - all parts are photosynthetic

28. Which substances pass through the open stomata of a leaf?






29. What tissue can be found in a root but not in a stem?






30. Which tissue system occurs throughout the plant - is made up of parenchyma - collenchyma - and sclerenchyma cells - and functions in storage - structural support - and metabolism?






31. What cellular processes generate short carbon chains or skeletons which plants use to assemble amino acids and lipids?






32. Vascular and seed bearing






33. What type of RNA has a codon?






34. Traits that are desirable can be selected and bred for. process of selectively mating and breeding plants with particular traits.






35. What cell undergoes meiosis?






36. How are the vascular bundles of a dicot arranged in the stem?

38. In double fertilization - one sperm cell fertilized an egg cell - What does the other sperm cell fertilize?






39. What part of a stem can a tree live without?






40. How is algae different from 'true' plants?






41. What hormone functions in stomatal closure and can be used to induce dormancy in cultivated plants?






42. 3 part molecule with a sugar - phosphate group - and nitrogenous base - carries genes






43. What pigment absorbs energy and can emit an electron in photosynthesis?






44. Epiphytes - valemine breaks down compost in roots






45. Individuals best adapted to their environment reproduce offspring. it requires variation - heritability - and selection.






46. During which phase of meiosis do daughter cells become haploid?






47. What are adenine - guanine - thymine - cytosine?
