Chapter 36, Problem 4IQ
a.
Summary Introduction
To explain: Transpiration.
Introduction: Xylem is a compound tissue present in the vascular plants. It conducts and supports nutrients and water upward from the roots that consist of vessels, woody fibers, tracheids, and parenchyma cells. The minerals and water that enter the symplast by an epidermal cell or cortex pass through the plasmodesmata of endodermis cells and to the stele or vascular cylinder.
b.
Summary Introduction
To explain: Tension.
c.
Summary Introduction
To explain: Cohesion.
d.
Summary Introduction
To explain: Adhesion.

- i just answered a hw question that i was a little confused on. i answered it but am not fully sure if it's correct. so can you take a look at check if my answer is correct and if it's not, then a explaintion would be helpful. Would you expect water molecules to move faster when there is a HIGH concentration gradient or a LOW concentration gradient? Water molecules would move faster when there is a high concentration gradient because the pressure for the molecules in the high concentration to reach equilibrium increases since there are more molecules there than in the low concentration. So as the molecules move down the concentration gradient faster to equalize the concentration on both sides due to the increased pressure, the rate of diffusion increases.arrow_forwardBoth water and the cytosol of cells are hydrophilic.
