Water is most likely to pass through the cell membrane via specialized protein channels known as aquaporins. These integral membrane proteins facilitate the rapid and selective transport of water molecules across the lipid bilayer, allowing for efficient regulation of water balance in the cell. Additionally, water can also diffuse through the membrane, albeit at a slower rate, due to its small size and polarity.
What else can I help you with?
Through what structure does water oxygen and carbon dioxide can enter a cell?
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
What structure regulates the movement of water into and out f a cell?
Cell membrane, specifically aquaporin proteins, regulate the movement of water into and out of the cell through a process called osmosis. These proteins create channels that selectively allow water molecules to pass through, maintaining proper water balance in the cell.
What Water enters a plant cell through the?
Water enters a plant cell primarily through osmosis, a process where water molecules move across the selectively permeable cell membrane. This occurs through specialized proteins called aquaporins, which facilitate the rapid transport of water. As water enters the cell, it helps maintain turgor pressure, essential for the plant's structure and growth.
What structure in a cell hold the water for the cell?
Vacuoles
How does the structure of the cell wall and cell membrane of a plant cell permeable to water?
The cell wall of a plant cell is made up of cellulose microfibrils that create small pores which allow water to pass through. The cell membrane contains proteins called aquaporins that form channels for water molecules to move in and out of the cell. Together, these structures facilitate the movement of water into the plant cell through osmosis.

What is the process of water moving down through the soil cell?
Water moves down through the soil cell by gravity, following the path of least resistance. As water percolates downward, it can be influenced by soil texture, structure, and compaction. The movement of water through the soil cell helps to recharge groundwater and provide moisture to plant roots.

What is least likely to be a factor in the movement of water through a terrestrial plant?
the influence of gibberellin on cell expansion
How does paremecium expel water?
Paramecium expels excess water through a specialized structure called the contractile vacuole. This organelle collects excess water that enters the cell through osmosis, and when it reaches a certain size, it contracts to expel the water out of the cell through a pore in the membrane. This process is crucial for maintaining osmotic balance and preventing the cell from bursting in a hypotonic environment.
In what plant cell structure is water stored?
Water is stored in the vacuole of a plant cell.
What cell part provides support for the cell allows gases and water to pass through and provides protection?
The cell wall is the structure that provides support for the cell, allows gases and water to pass through, and provides protection by maintaining the cell's shape and rigidity. It is found in plant cells, bacteria, fungi, and some protists.
What is a structure that moves material through a cell?
it's the cell membrane
What are the special structures in the cell that allow materials such as water and sugar to pass through?
The cell membrane is the special structure that allows materials to pass through, utilizing channels and transport proteins to facilitate the movement of water and sugars in and out of the cell. This selective permeability helps regulate the internal environment of the cell and maintain homeostasis.
How does paramecium expel water?
Paramecium expels excess water by contracting its contractile vacuole, a specialized structure that accumulates and pumps out water from the cell. This helps maintain the proper internal environment and osmotic balance within the cell.
