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






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






3. Vascular and seed bearing






4. 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






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






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






7. How does DNA replication take place?






8. Southern US - prop roots hold it in place as water moves out - it can breathe under water.






9. What causes diffusion of gases to occur?






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






11. If an ovule is fertilized - what will it develop into?






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






13. What is considered part of the protoplast?






14. 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.






15. Info. carrying molecule - single stranded






16. How does DNA replication take place?






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






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






19. 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.






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






21. Under what conditions would a plant utilize fermentation to obtain energy?






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






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






24. 'Alleles' are best described as...






25. Enzymes are an example of what type of molecule?






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






27. 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






28. What is a product of the biochemical reactions of photosynthesis?






29. Don't have roots or leaves - and are not producers - do not photosynthesize - and have cell walls made out of chitlin.






30. Which part of aerobic respiration generates the most ATP?






31. What are the major groups of algae?

35. What is a product of the biochemical reactions of photosynthesis?






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






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






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






39. What organelle was observable in the onion epidermis stained with iodine?






40. In what portion of a root might you find 'root hairs'?






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