Detailed explanation-1: -Water channel proteins named aquaporins, which are found in the membranes of root cells, are thought to mediate these adjustments. Their study provides an interesting model to understand the regulation of water transport in plants and sheds light on the basic mechanisms of water uptake by roots.

Detailed explanation-2: -Aquaporins (AQP) are integral membrane proteins that serve as channels in the transfer of water, and in some cases, small solutes across the membrane. They are conserved in bacteria, plants, and animals.

Detailed explanation-3: -Aquaporins are a type of membrane protein. These work as water channels in the membrane. They help in transporting water molecules and sometimes solutes across the membranes. This type of transport is known as facilitated diffusion.

Detailed explanation-4: -Water is the most abundant molecule in any cell. Specialized membrane channel, proteins called aquaporins, facilitate water transport across cell membranes.

Detailed explanation-5: -Answer and Explanation: The type of transport that occurs through aquaporins is a form of passive transport known as osmosis. Osmosis is the movement of water through a semipermeable membrane from high to low concentration.
