Botany Test

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. How are the vascular bundles of a dicot arranged in the stem?






2. 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






3. Have a nucleus - and a cell membrane






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






5. Differences in type and location of human-managed ecosystems - quantity and quality of available drinking water and air may also be affected by rising levels of atmospheric carbon dioxide






6. What is the role of endosperm?






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






8. What process involves the movement of water across a semi-permeable membrane?






9. During which phase of the cell cycle does DNA replication occur?






10. Vascular and seed bearing






11. Iodine can be used to test for what molecule - resulting in a blue-black color?






12. Vascular and seed bearing






13. The part of an apple most often eaten by people is receptacle tissue - not ovary - making this what type of fruit?






14. What process would be used by a plant to move potassium ions across a membrane AGAINST a concentration gradient?






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






16. 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.






17. Where in the chloroplast do protons accumulate - resulting in an electrochemical gradient which drives ATP-synthase?






18. During which phase of mitosis do the sister chromatids separate?






19. What is the primary function of collenchyma cells?






20. What is a final product of aerobic respiration?






21. What is considered part of the protoplast?






22. How do bacteria reproduce?






23. What BEST describes plant hormones?






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






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






26. What is NOT a function of the vacuole?






27. How does DNA replication take place?






28. You can determine the age of a woody branch by counting these






29. What are beneficial products made from bacteria?






30. A plant that carries two different versions of a gene for a single trait is...






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






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






33. Have a cell wall - no membrane - and no nucleus






34. Have a cell wall - no membrane - and no nucleus






35. Epiphytes - valemine breaks down compost in roots






36. Heating up bacteria until it is harmless and cannot function.






37. Three generations of gymnosperms






38. The ocular lens of a microscope is 10x - and the objective lens is 4x. What is the total magnification of the microscope?






39. What are homologous chromosomes?






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






41. Lives in desert - leaves have waxy cuticle - succulent - holds onto water






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






43. Transferring of the information from the DNA into the language of the mRNA.






44. Where in a dicot leaf does the majority of photosynthesis occur?






45. What are harmful effects of bacteria?






46. A piece of potato tuber is placed in a concentrated sugar-water solution. what statement BEST describes why the piece of potato shrinks in size over time?






47. Seedless - multicellular - and terrestrial - have a vascular system - reproduce by spreading spores that are found on the underside of mature leaves.






48. 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.






49. What process involves the movement of water across a semi-permeable membrane?






50. A tissue in Which mitosis takes place - giving rise to the secondary xylem.
