Yes, large cells and small cells both carry out diffusion and osmosis, but the rates can differ. Smaller cells generally have a higher surface area-to-volume ratio, allowing for more efficient and faster diffusion and osmosis compared to larger cells. As cells increase in size, the volume grows faster than the surface area, which can slow down these processes. Therefore, smaller cells typically exchange materials more rapidly than larger cells.
What else can I help you with?
What is one specific form of simple diffusion?
There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.
What process does the water move from the large intestines to the blood stream?
i want to say passive diffusion but i dont know for sure
How does a single celled organism get its nutrients?
Easy!! diffusion.. because single celled organisms have a large surface area to volume ratio meaning that there exchange surface is large enough to allow efficient diffusion fast enough to keep the cells alive (1 cell.. lol ). they also aren't very active they can rely on diffusion alone to take up water and other important solutes.. Diffusion through osmosis occurs in single celled organisms when they have a lower water potential inside the cell than outside so water flows into the cell (down the concentration gradient) via a partially permeable membrane. hope that helped from Kate Gibson 16
Which of the following would not move by diffusion across a capillary into the surrounding tissue?
Large proteins and cells like red blood cells would not move by diffusion across a capillary into the surrounding tissue. Diffusion is limited to small molecules and ions that can pass through the tiny gaps between endothelial cells.
How does osmosis and diffusion help an amoeba survive?
Osmosis and diffusion help an amoeba survive by allowing it to take in essential nutrients and water from its environment and release waste products. Through these processes, the amoeba is able to maintain the necessary balance of molecules and ions inside its cell to support its biological functions.
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.
What are some reasons osmosis and diffusion are not sufficient reasons for the transport of all substances to pass in and out of cells?
Some substances are too large to pass through the cell membrane via osmosis or diffusion. Additionally, some substances require specific carrier proteins or energy input to be transported across the membrane. Finally, certain substances may need to move against their concentration gradient, which cannot be achieved through osmosis or diffusion alone.
What two processes move large packets of molecules across the cell membrane?
osmosis and diffusion
What is one specific form of simple diffusion?
There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.
Why is osmosis's important cells?
Cells need to get rid of large particles they don't need
Movement of large molecules into a cell is called?
hydrogen bondingANS2:Substances are moved into cells by both active transport and passive transport. An example of active transport is "Endocytosis". An example of passive transport is "Diffusion".
What are three types of passive transport?
Diffusion- is the movement of the substance from an area of higher concentration to an area of lower concentration,Osmosis- is the diffusion of water molecule only through a membrane semipermeable cell membranes allow water to pass through them until equilibrium occurs.Facilitated Diffusion- carrier proteins, and channel proteins it occurs when molecule pass through a cells membrane.
Can sucrose enter the cells by osmosis?
No, sucrose cannot enter cells by osmosis. Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Sucrose is a large molecule and cannot pass through the cell membrane via osmosis.
What process does the water move from the large intestines to the blood stream?

Give 2 examples of passive transport?
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.

What type of diffusion takes place when a plant cell absorbs water?
The plant cell absorbs water by simple diffusion and osmosis. Also water can pass from cell to cell through the Plasmodesmata (which are communication channels through the cell wall from cell to cell, providing a very easy and important method for water transportation between the cells ). Also, the large area inside the cells occupied by the vacuoles increases the osmotic pressure ,and that in turn facilitates diffusion. It's note worthy that water passes through many different types of diffusion before reaching the cell environment where it will be absorbed by simple diffusion as we have said. To give you an example about the journey of water from the roots to the cells, the plant vessels absorb water by using methods like diffusion and active transport. In the Phloem, Sucrose is absorbed by active transport ( a process that increases the osmotic pressure ) and as a consequence water enters inside it by osmosis.
