The higher osmotic potential in the plant cells (root hairs and its surrounding cells) is the cause of entering water in plants from the soil by endo-osmosis. Once the water reaches near xylem it is pulled upward by cohesion force. And thus the continuity of water entring in the root is maintained.
What else can I help you with?
How is osmosis involved in supplying water for photosynthesis in the leaf?
Because osmosis is related to the movement of water molecules.
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 is the tissue responsible for transporting water and minerals from the root to the stem and leaves?
The tissue responsible for transporting water and minerals from the root to the stem and leaves is called xylem. Xylem is a type of vascular tissue that consists of specialized cells that form vessels for conducting water and nutrients.
Water enters a plant through which structures?
roots/root hairs.
A force which pushes water from root xylem into stem xylem?
Cohesion tension pulls water up the xylem due to the transpiration stream caused by the evaporation of water from the stomata. Cohesion tension results from the Hydrogen bonding in water which means that water molecules cohere or stick to one another. As water evaporates from the stomata, more water is drawn up into its place, and so there is a continuous stream of water molecules which are drawn up the xylem.

How does water get into the xylem vessels in roots?
Water enters the xylem vessels in roots primarily through a process called osmosis, where water moves from an area of higher water potential in the soil to an area of lower water potential in the root cells. This movement is facilitated by root hairs and specialized cells in the root, such as the endodermis. Additionally, the process of transpiration in leaves creates a negative pressure in the xylem, which helps pull water up from the roots.
Describe the pathway followed by a water molecule from the time it enters a plant root to the time it enters a plant root to the time it escapes into the atmosphere from a leaf?
A water molecule enters a plant root through specialized cells called root hairs and moves up through the xylem tissue, driven by capillary action and transpiration pull. It then flows through the stem and into the leaf where it exits the plant through tiny pores called stomata as water vapor, a process known as transpiration.

Water enters a plant through which structures?

Does mineral salt enters the root cells by diffusion or active transport?
Mineral salt enters the root thru active transport, after it enters, the mineral salt is passed on to another root cell through diffusion to move to the xylem tube then it moves up the tube via transpiration pull
Where does the xylem get water?
The xylem gets water from the roots of the plant through the process of transpiration and root pressure. Water is absorbed by the plant's roots from the soil and transported through the xylem tissues to the rest of the plant.
A force which pushes water from root xylem into stem xylem?
Cohesion tension pulls water up the xylem due to the transpiration stream caused by the evaporation of water from the stomata. Cohesion tension results from the Hydrogen bonding in water which means that water molecules cohere or stick to one another. As water evaporates from the stomata, more water is drawn up into its place, and so there is a continuous stream of water molecules which are drawn up the xylem.
What two structures does water and minerals pass through to get to xylem?
Water and minerals pass through the root epidermis and root cortex cells to reach the xylem in plant roots. The root epidermis is the outermost layer of cells in the root, and the root cortex is a region of parenchyma cells between the epidermis and the vascular tissue (xylem and phloem).
What structure transport water and nutrients from the root to the rest of the plant?
Xylem
How water gets in to a root hair cells from the soil?
By a tissue xylem
