Question

A steroid hormone will bind to Select one: O a. a receptor molecule inside a cell. O b. DNA, facilitating transcription. O c. a protein embedded in the cell membrane. O d. secondary messenger molecules in the cytoplasm. Select the correct order in which water can move through the tissues of a plant: Select one: O a. mesophyll xylem stomata O b. xylem stomata mesophyll C. Stomata ? xylem ? mesophyll O d. xylem mesophyll stomata Stomata are located on the underside of the leaf and are flanked by guard cells. These guard cells close the stomata by Select one: 0 a, taking in water by osmosis due to an accum ulation of K+. This results in turgor in the guard cells that seals off the stomata. O b. taking in water by osmosis due to a loss of K. This results in turgor in the guard cells that seals off the stomata. C, losing water by osmosis due to an accumulation of K+. This results in a loss of turgor in the guard cells that seals off the stomata. d. losing water by osmosis due to a loss of K. This results in a loss of turgor in the guard cells that seals off the stomata.

Explanation / Answer

Answer 1. The correct option is a. A receptor molecule inside a cell.

Answer 2. The correct option is D. Xylem --> Mesophyll --> Stomata.

Answer 3. The correct option is D. Losing water by osmosis due to a loss of K+. This results in a loss of turgor in the guard cells that seals off the stomata.
