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. 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.

3. What organelle do guard cells contain that other epidermal cells lack?






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






5. How do bacteria reproduce?






6. What cell undergoes meiosis?






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






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

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






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






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






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

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






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






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






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






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






32. 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.






33. What are harmful effects of bacteria?






34. What is NOT a function of the vacuole?
