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. Under what circumstance would sexual reproduction be more successful than asexual reproduction?






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






3. Which class of organic macromolecule stores the greatest amount of potential energy?






4. Which part of aerobic respiration results in the production of CO2?






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






6. What cell undergoes meiosis?






7. What is the primary function of collenchyma cells?






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






9. What is the role of endosperm?






10. What structure is MOST important in generating root pressure?






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






12. What are the major groups of algae?






13. 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.






14. 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






15. What are beneficial products made from bacteria?






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






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






18. What organelle contains DNA?






19. What is the function of the cortex in a root?






20. 'Alleles' are best described as...






21. How many sperm cells does each pollen grain typically carry?






22. Info. carrying molecule - single stranded






23. 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.






24. What is considered part of the protoplast?






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






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






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






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






29. Which commonly eaten food is an example of a stem?






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






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






32. Under what circumstance would sexual reproduction be more successful than asexual reproduction?






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

39. What plant tissue functions in conducting water from the roots to the leaves?






40. What is considered part of the protoplast?






41. 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






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