If a plant's leaves developed so that its vascular tissue only contained xylem, how would this affect the rest of the plant's ph
Snezhnost [94]

Answer:

If a plant's leaves only contained the vascular tissue xylem, then it will not be possible for the plant to absorb carbon dioxide. As carbon dioxide is required for photosynthesis to occur, this means that the process of photosynthesis will not take place. As a result, the plant will not be able to produce food as photosynthesis is the process by which plants make food. This will result in the plant to die eventually in the end due to lack of food.

This is the unequal distribution of ions across a cell membrane.
Nady [450]

Answer:

Concentration gradient

Explanation:

Concentration gradient of the ions across the membrane generates the membrane resting potential.

Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
