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.

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






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






42. 3 part molecule with a sugar - phosphate group - and nitrogenous base - carries genes
