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.

32. What cell undergoes meiosis?






33. Have a nucleus - and a cell membrane






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






35. 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.
