Water moves inward in the root through a process called osmosis, where it travels from the soil into root cells that have a higher solute concentration. Once inside the plant, water moves upward through the stem via capillary action in the xylem vessels, aided by transpiration, which creates a negative pressure that pulls water upward from the roots to the leaves. This combination of osmotic movement and capillary action ensures efficient water transport throughout the plant.

What tissue carries water in a plant root?
In a plant root, the tissue responsible for carrying water is primarily the xylem. Xylem vessels transport water and dissolved minerals from the roots upward to the stems and leaves through a process known as transpiration. This movement is driven by capillary action and the evaporation of water from the leaves, creating a negative pressure that pulls water upward. Additionally, the surrounding root tissues, such as the cortex, facilitate the initial uptake of water from the soil into the xylem.
How does transport of water occur at night in absence of transpiration?
At night, when transpiration is reduced or absent, water transport in plants primarily occurs through capillary action and root pressure. Capillary action helps move water upward through the xylem due to cohesion and adhesion properties of water. Additionally, root pressure, generated by the osmotic uptake of water in the roots, can push water upward, though this effect is generally more pronounced during the day when transpiration is active. Thus, while night conditions limit transpiration, plants can still transport water through these mechanisms.
How do roots transfer water to the leaves?
Roots absorb water from the soil through tiny hair-like structures called root hairs. This water then travels through the plant's vascular system, specifically the xylem, which acts like a series of tubes. Capillary action, root pressure, and transpiration pull work together to move the water upward against gravity to the leaves, where it is used for photosynthesis and other physiological processes.
Why and how does water enter continuously in the root xylem?
Water enters the root xylem continuously mainly due to two processes: root pressure and transpiration. Root pressure is generated when minerals are actively absorbed by root cells, creating a concentration gradient that draws in water through osmosis. Additionally, the process of transpiration, where water evaporates from the leaves, creates a negative pressure that pulls water upward through the xylem from the roots. This combination of root pressure and transpiration ensures a continuous flow of water from the soil into the plant's vascular system.
What force helps move water up through plants?
Capillary action, transpiration, and root pressure move water up through the plant.

What is root pressure and how is it different from capillary action?
Root pressure is the upward force that drives water and nutrients from the roots of a plant into the stems and leaves, primarily generated by osmotic pressure within the root cells. It occurs when water is absorbed from the soil and creates a concentration gradient that pushes water upward. In contrast, capillary action is the ability of water to move through small spaces, such as the tiny vessels in plants, due to cohesive and adhesive forces. While root pressure is a physiological process driven by osmotic gradients, capillary action is a physical phenomenon related to the properties of water and plant structures.
What is the sequence of structures through which water passes into the root?
Water passes through the root hairs, then the epidermis, cortex, endodermis, and finally reaches the xylem where it is transported upward through the plant.

How does water and minerals move to the center of the root?
Water and minerals are absorbed by root hairs located on the surface of the root. From there, they move through the root's epidermis, cortex, and endodermis layers via osmosis and active transport. The endodermis layer acts as a selective barrier and helps regulate the movement of water and minerals towards the center of the root.
Why does water move from the soil into the root hair cell?
osmosis
Is intern a root word?
No, "intern" is not a root word. It is derived from the Latin word "internus," meaning 'internal' or 'inward.'
Which two processes can make the water in the tray available to the plant?
The two processes that make the water in the tray available to the plant are capillary action and root uptake. Capillary action allows water to move upward from the tray into the soil through tiny spaces in the soil particles. Root uptake occurs when the plant's roots absorb water from the surrounding soil into the plant's system for utilization in various biological processes.
