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. What pigment is responsible for plants sensing day length?






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






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






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






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






6. Info. carrying molecule - single stranded






7. What is NOT a product of the krebs cycle?






8. What type of fruit develops from a cluster of many simple flowers?






9. 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






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






11. Lives in california - it is a lily - waxy - thin - sharp leaves to stop water loss - holds water for up to 2 years.






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






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






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. Epiphytes - valemine breaks down compost in roots






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


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






18. An ecosystem with similar climatic conditions on earth - such as communities of plants - animals - and soil organisms






19. 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






20. Info. carrying molecule - single stranded






21. Change in gene frequency in a gene population over time.






22. What is NOT a function of the vacuole?






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






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






25. 'Alleles' are best described as...






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






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






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






29. What are beneficial products made from bacteria?






30. Where in a plant is the water potential lowest?






31. What is a reactant in the photochemical reactions of photosynthesis?






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






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






34. During which phase of mitosis does the nuclear envelope disappear?






35. What type of RNA has a codon?






36. What hormone stimulates cell division and may interfere with the function of auxin - leading to the development of 'witches-broom'?






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






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






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






40. Vascular and seed bearing






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






42. 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.






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






44. What BEST describes plant hormones?
