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. 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.






2. What is NOT a structure found on a typical flowering plant?






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






4. Individuals best adapted to their environment reproduce offspring. it requires variation - heritability - and selection.

17. 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






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






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






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