Aloiza [94]

Answer:

I'm a eukaryotic, plant cell. I would be the central vacuole that stores excess water, food, and waste. There's only one of me in a plant cell. If I weren't in the cell, it would collapse or burst, because it well lose its turgor pressure. Moreover, the cell won't have enough space to store all the water and molecules needed for conducting photosynthesis.

All of the following enhance water transport in terrestrial plants except: a) hydrogen bonds linking water molecules. b) capilla
Nimfa-mama [501]

Answer:

D) K being transported out of the guard cell.

Explanation:

The movement of water in the terrestrial plants is a very important factor as each cell of the plant require water to survive.

The movement of water is influenced by many physical, chemical and process going on in the plants like transpiration and stomatal opening and closing.

Water posses adhesion and cohesion properties which allow the water molecules to form a bond with other surface and with each other respectively. This allows the movement of water in the xylem by a process called capillary action.

The evaporation of water creates a pressure on the plant to absorb water from the soil but when potassium ions move out of the guard cell of stomata, the guard cells lose turgidity and stomata gets closed.

Thus, Option-D is correct.
