Question

Which of the following is not true of the xylem?

A. Contains water
B. Comprised of living cells
C. Has thick cells walls
D. Contains dissolved minerals

Which is true of auxins?
A. Affect mitosis
B. Open the stomata
C. Concentration is gravity dependent
D. Control leaf budding

Answer 1

For the first question, it is B since xylem does not have living cells and instead have dead cells unlike phloem. The other answers are correct since it carries and transports water and dissolved minerals and has thick cell walls with a hallow lumen.

For the second question, I am not exactly sure but it might be A since it promotes cell division and mitosis is a type of cell division. You might wanna double check that one, though.

Hope I've helped. :)
