48 multiple choice 1 point
which of the following is not part of transpiration-cohesion-tension mechanism?
water evaporates from the walls of mesophyll cells
removal of water from the xylem exerts a pull on the water column
water is remarkably cohesive
pumping action of the individual cells along the xylem force water in an upward direction

while snorkeling or skin diving, a student observes an active marine animal that has a series of muscular tentacles bearing suckers associated with its head. a pair of large, well - developed eyes are evident. the student is observing an animal belonging to the class:

Explanation:

First Question (Characteristics of Plants Except):

Plants are autotrophs (perform photosynthesis) to make their own food, while heterotrophic organisms depend on others for food. Multicellularity with specialized tissues/organs, photosynthesis with chlorophylls a and b, and cell walls with cellulose are plant characteristics. So "heterotrophic" is not a plant characteristic.

The transpiration - cohesion - tension mechanism involves water evaporation from mesophyll cells (transpiration), cohesion of water molecules, and tension from water removal in xylem. Xylem cells are dead and don't pump water; water movement is due to transpiration pull, cohesion, etc. So the pumping action of xylem cells is not part of this mechanism.

Animals with muscular tentacles bearing suckers on the head and well - developed eyes are in the class Cephalopoda (e.g., octopuses, squids). These animals are active marine predators with such features.

Answer:

C. heterotrophic
