Botany - Transport in Plants Question with Solution | TestHub
The adsorption of water by hydrophilic compounds like cellulose and pectin in root hair cell wall is called _______.
Options:
Answer:
Solution:
It is a physical process which involves adsorption and/or absorption of water by hydrophilic substances without forming a solution e.g., wooden doors absorb water and swell up in rainy season and seeds of pea and gram when placed in water swell up due to imbibition
The imbibition process involves diffusion and capillary action.
In imbibition, Liquid substance (water) is called imbibate, and solid colloidal substance is called imbibant. e.g. the gum, dry wood, cell protoplasm, seed coat, etc. Due to imbibition, water molecules remain held (absorbed) over the surface of hydrophilic particles and also remain held between the space of particles of imbibant.
