The cohesion-tension theory describes how water moves from the roots to the leaf. Osmosis causes water to enter the xylem of roots from the soil. Due to the hydrogen bonding between the water molecules, water forms a string of molecules as it moves to the xylem. Constant transpiration at the top of the leaf pull the water molecules out of the plant. The differences in water potentials and pressures cause this fairly constant movement of water through the plant.

∙ 13y agoThe cohesion tention hypothesis is based on a well known phonomena including the molecular properties of water and transpiration. The system exerts pressure that causes water and other mlecules to ooze out of a cut plants stem.

What is a verbal hypothesis?

What is a causal hypothesis?
A causal hypothesis is a proposed explanation for a cause-and-effect relationship between two or more variables. It suggests that changes in one variable directly influence changes in another variable. Researchers test causal hypotheses through experiments or empirical studies to determine the validity of the proposed relationship.
What should you do after you form a hypothesis?

What is the difference between a hypothesis and a working hypothesis?
The difference is that working hypothesis is that your still working on it but the hypothesis that your not working on it.
What is the outcome of hypothesis testing?
a. the hypothesis ispartly true but needs to be revised. b. the hypothesis wrong. c. the hypothesis is supported. d. the hypothesis is of no value.
What causes hypothesis to be rejected?
We have two types of hypothesis i.e., Null Hypothesis and Alternative Hypothesis. we take null hypothesis as the same statement given in the problem. Alternative hypothesis is the statement that is complementary to null hypothesis. When our calculated value is less than the tabulated value, we accept null hypothesis otherwise we reject null hypothesis.
