BIOXI11: TRANSPORT IN PLANTS

336215 Which of the following is true about the transpiration pull?

1 The upward movement of water into the phloem
2 The concentration of solute is increased in mesophyll cells
3 The upward movement of water into the xylem vessels
4 All of the above
BIOXI11: TRANSPORT IN PLANTS

336216 Symplastic movement is slower than apoplastic movement

1 Because it involves cytoplasmic streaming always
2 Molecules has to enter through cell membrane
3 Because it is down the gradient
4 All the above
