Question

Transport in plants involves all of the following processes EXCEPT Select one: O a. adhesion of water molecules to cellulose. O b. cohesion between water molecules. O c. evaporation of water molecules. O d. active transport through xylem cells. O e, transport through tracheids. Select the correct function of guard cells: Select one: O a. protect the endodermis O b. accumulate Kt and close the stomata c contain chloroplasts that import K. directly into the cells d. guard against mineral loss through the stomata e, help balance the photosynthesis-transpiration compromise O O

Explanation / Answer

1. Answer (d) active transport through xylem cells.

Xylems are heavily lignified and impermeable to water, thus no active transport can take place through xylem.

2. Answer:(e) help balance the photosynthesis-transpiration compromise.

The main function of guard cells is to prevent an excess loss of water through respiration, allowing the plant to perform photosynthesis by trading oxygen and carbon dioxide without becoming dehydrated.
