How does water enter or leave the uni cellular organism by diffusion or osmosis?
In unicellular organisms, water enters the cell through the process of osmosis, which is the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. This helps maintain the cell's internal hydration levels. Similarly, water can also leave the cell through osmosis if the external environment has a lower concentration of water than inside the cell.
What process does water enter root hair cells?
BY osmosis i.e the concentration gradient created between the outside and the root hairs cells. Water will flow from a high area of concentration to a low area of concentration across a partially permeable membrane
How do mineral salts enter the root cell?
Minerals enter the root cells through a process called diffusion.Minerals are found dissolved the soil around the root. When minerals dissolve in water they break up into ions. These ions are very small and enter through the holes in the cell membrane.The absorption of mineral salts take place through the root hairs.When the mineral concentration is higher in the soil than in the cells of the root hair then the minerals pass through the cell membrane -from a higher concentration of minerals in the soiltoa lower concentration of minerals in the root hair cells.This process is called diffusion and does not require energy.
How do substances from the soil solution enter the roots of plants?
Substances enter the roots of plants through a process called root uptake. Root uptake involves the movement of water and solutes by various mechanisms such as diffusion, osmosis, and actively transporting ions into root cells. This process allows plants to absorb essential nutrients and water from the soil solution.
How do water and minerals get to each cell in a plant?
Water and minerals are absorbed by a plant's roots from the soil. They are then transported through specialized tissues called xylem to the leaves and other parts of the plant. From the xylem, water and minerals enter each cell through osmosis and diffusion to support various cellular processes.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
How does dissolved oxygen enter the ocean?
Diffusion.
How does pure water enter a cell?
through diffusion and osmosis. :-)
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
What process cause the water to enter or leave the cell?
the process that causes the water to enter and leave the cell is diffusion
What substance cannot be moved into a cell by osmosis or diffusion?
Large molecules such as proteins cannot be moved into a cell by osmosis or diffusion due to their size and charge. These molecules require specialized transport mechanisms such as active transport to enter the cell.
3 ways materials enter and leave cell?
Materials can enter a cell through processes like diffusion, facilitated diffusion, and active transport. These substances can leave a cell through processes such as diffusion, osmosis, and exocytosis.
What Dissolves particles allowing them to enter a solution?
A solvent is the liquid medium that dissolves particles so they can enter a solution. This is necessary in the processes of diffusion and osmosis.
A what dissolves particles allowing them to enter a solution?

Does oxygen enter a cell by diffusion or osmosis?
Oxygen enters a cell by diffusion, which is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis, on the other hand, is the movement of water molecules across a selectively permeable membrane.
Why is diffusion and osmosis important to the cell?
Diffusion and osmosis are essential processes for maintaining the balance of molecules and ions inside and outside the cell. Diffusion allows for the movement of nutrients and waste products across the cell membrane, while osmosis regulates the movement of water to prevent the cell from swelling or shrinking. Together, these processes help cells maintain homeostasis and support their survival.
What are bands of ore that form when minerals dissolved in water and enter cracks in rocks?
veins
