Question

Which of the following is a rapid type of water absorption?

• A. Active absorption
• B. Passive absorption
• C. Continuous absorption
• D. Pulsating absorption

Answer 1

The correct option is B Passive absorption

Passive absorption is the type where the water absorption is through the transpiration pull. This creates tension or force that helps in the movement of water upwards into the xylem sap.
It occurs in rapidly transpiring plants during the daytime, because of the opening of stomata and the atmospheric conditions. The water will enter the plant via the root cells that can be found in the roots where mainly passive absorption occurs.
Over small distances substances move by diffusion and by cytoplasmic streaming supplemented by active transport.
