We will finish studying the root structure and how it functions, and then finish answering and marking the questions (if you have not already done so).

Study the stem of the plant. Once again (just like for the roots), understand how the structures function in a logical way for the plant to be able to operate. And THEN learn the big names of the structures. The answers to the questions have been included here. (Remember, YOU are the loser if you do not do this properly. Conditions have dictated that this is the way we answer and mark the questions.)
