What is the process controlled by sodium potassium and chlorine whereby fluids flow in and out of cells through the cell walls?
osmosis
Are tracheids alive at maturity?
Dead , their walls become lignified. Lignin is waterproof and prevents osmosis occurring so the cell dies.
The process of water moving out of a cell is called?
OSMOSIS More specifically: Endosmosis is the movement of water into a cell Exosmosis is the movement of water out of a cell
How does a plant cell fight osmosis in a hypotonic solution?
Osmosis is the diffusion of water - and a hypotonic solution means it expands. a plant cell sap has a lower water potential causing the water to enter the cell - it does not fight osmosis, it works with it.
What causes a cell of shrink because of osmosis?
What causes a cell to shrink because of osmosis?
How is cellular structure beneficial to plants and animals?
Plants have cell walls that prevent them from dessication (water loss). Animals lack cell walls because of nutritional requirements that need to enter the cell via diffusion or osmosis.
What is the process controlled by sodium potassium and chlorine whereby fluids flow in and out of cells through the cell walls?
osmosis
Is osmotic pressure essential for the survival of the organism?
Yes. Organisms use osmosis to absorb nutrients across cell walls.
Plants with rigid cell walls are unable to do which process Diffusion Osmosis Active Transport or Phagoctyosis?
Phagocytosis. This is the process where the cell actively engulfs other elements.
Why is osmosis important to cell function?
Osmosis is important to cell functions because it keeps the cell alive
Are tracheids alive at maturity?
Dead , their walls become lignified. Lignin is waterproof and prevents osmosis occurring so the cell dies.
What is the function of pressure?
Turgor pressure forces plasma membrane against cell walls of plants and bacteria. The pressure is caused by osmosis.
The process of water moving out of a cell is called?
OSMOSIS More specifically: Endosmosis is the movement of water into a cell Exosmosis is the movement of water out of a cell
When a plant with flexible cell walls is placed in a hypertonic solution what happens?
The plant with flexible cell walls when placed in a hypertonic solution tends to grow larger in size by uptaking the solution by the principle of osmosis where molecules from higher concentration moves to a region of lower concentration and this happens in the cell through small minute pores present in the cell walls.
How does a plant cell fight osmosis in a hypotonic solution?
Osmosis is the diffusion of water - and a hypotonic solution means it expands. a plant cell sap has a lower water potential causing the water to enter the cell - it does not fight osmosis, it works with it.
What controls diffusion and osmosis in and out of a cell?
the nucleus controls both osmosis and diffusion in and out of a cell
What causes a cell of shrink because of osmosis?
