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






2. Have a nucleus - and a cell membrane






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






4. What contains the most potential energy?






5. 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






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

14. What separates during meiosis-II






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






16. A gymnosperm - lives in the desert for up to 3000 years - only grows 2 leaves - 5 feet across - they receive 1 inch of lower of rainfall per year - roots can grow under the soil at least a mile.






17. In what part of a flower is pollen produced?






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






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






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






21. A gymnosperm - lives in the desert for up to 3000 years - only grows 2 leaves - 5 feet across - they receive 1 inch of lower of rainfall per year - roots can grow under the soil at least a mile.






22. What are beneficial products made from bacteria?






23. Composite organisms consisting of a symbiotic organism composed of a fungus with a photosynthetic partner - can be used as a natural fertilizer






24. What type of RNA has an anticodon?






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






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






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






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






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






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






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






32. What is the main function of the roots of a corn plant?






33. 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.






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






35. 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.

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






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






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






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