Why do cells use the process of diffusion?
Diffusion is essential for cells to bring nutrients and releasing wastes without spending energy.
What controls the passage of nutrients into the cell and wastes out of the cell?
The plasma membrane controls the passage of nutrients into the cell and wastes out of the cell through a process called selective permeability. This involves transport proteins and channels that regulate the movement of molecules based on size, charge, and concentration gradients.
What will happen if there is no osmosis in an organism?
Cells cannot be alive and function without osmosis. Osmosis helps to maintain an equilibrium between the pressure within the cell and outside the cell. If the fluid volume within the cell is more than the fluid volume outside the cell, the cell swells up due to the excess fluid and pressurize the cell wall causing it to burst. If the fluid volume outside the cell is less than the fluid volume inside the cell, the pressure exerted on the cell wall from outside will cause the cell to cave in and collapse. In plants osmosis helps to absorb water and nutrients and transfer it to other parts of the cell. In animal cells it aids in distribution of nutrients and removal of toxic wastes. Living organisms cannot live without the process of osmosis.
What breaks down remains and wastes?
Decomposers such as bacteria, fungi, and insects break down remains and wastes into smaller, simpler molecules through the process of decomposition. These organisms play a crucial role in recycling nutrients back into the ecosystem.
Do animal cells store wastes in their vacuoles?
Yes. Animal cell vacuoles do hold wastes, along with water and nutrients.
What is the movement of wastes out of the cell membrane called?
Diffusion and Osmosis
Why do cells use the process of diffusion?
Diffusion is essential for cells to bring nutrients and releasing wastes without spending energy.
Can cell shape influence the rate of diffusion of nutrients and wastes?
hmmm????????? bcz of science?????
Exchange of nutrients and wastes with the body cells takes place by diffusion through the walls of?
artria
Where in the circulatory cyctem does nutrients enter and wastes leave the tissues?
The capillaries are the site in the circulatory system where nutrients enter and wastes leave the tissues. The thin walls of the capillaries facilitate this diffusion.
How do single celled organisms exchange nutrients and wastes with their environment?
Single-celled organisms exchange nutrients and wastes through processes like diffusion, osmosis, and active transport. Nutrients are absorbed through the cell membrane from the surrounding environment, while wastes are expelled back out. This exchange occurs based on concentration gradients and the needs of the cell for survival.
What is the process of moving nutrients and wastes in a living thing?
Excretion
What is the use of the capilaries?
The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.
What do the capillary do?
Capillaries are the site of diffusion of materials between the body tissues and the blood stream. These materials include nutrients, oxygen, and wastes.
What is a capillary features?
A capillary has a very narrow lumn and very thin wall. These features maximize diffusion of nutrients, wastes, and oxygen.
What happens when blood flows through capillaries?
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
How do oxygen food nutrients and waste exchange in the capillaries?
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.
