Which of the following structures is not found in bryophytes?
a cellulose cell wall
chloroplast
sporangium
root

The answer is ROOT

Explanation: Briophytas belong to the plantae kingdom, therefore they have a cell wall in their cells, and chloroplasts. They have sporangia (structure where the spores are produced and stored)  but they do not possess proper roots. Instead they have a structure called "rhizoid" whose function is the fixation to the substrate.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
