Active transport in plant root cells requires that those cells have access to O2. Normally there is enough
O2 available in air pockets in the soil, but flooded soil has very little O2. Thus, unless they have special
adaptations, plants in flooded soil effectively have no active transport in their roots. Which of the
following should you expect to occur for trees without special adaptations to flooding after several
days in flooded soil?
a. excess uptake of water and minerals in the xylem
b. wilting of their leaves
c. bursting of leaf cells due to excess water flow
d. excess water pushed out at the margins of their leaves
e. excess uptake of water and minerals in the xylem, and excess water pushed out at the
margins of their leaves
