A) Hydrogen bond
B) Turgor pressure
C) Hydrophilic cell walls
D) Osmosis
Correct Answer: A
Solution :
[a] Water is a polar molecule and forms hydrogen bonds between the positively charged hydrogen atoms and negatively charged oxygen atom. Hydrogen bonds made water molecules stick together, a process known as cohesion. When water molecules form hydrogen bonds with other molecules, such as carbohydrates, it is called adhesion. The hydrogen bonds have tension between them. So, water molecules stick together and move together.
