SAT Subject Test: Biology

Subjects : sat, science, biology
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. Tissue formed by the differentiation of cambium that causes a growth in width of a plant system






2. The conversion of digested foods and other materials into forms usable by the body (i.e. - the conversion of amino acids into proteins)






3. Cytoplasmic bodies within a plant cell that are often pigmented






4. Nonfunctional haploid cells created during meiosis in females; they have very little cytoplasm-most has gone into the functional egg cell
