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 BEST describes plant hormones?






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






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






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


5. Enzymes are an example of what type of molecule?






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






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






8. Where in a dicot leaf does the majority of photosynthesis occur?






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






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