How does cell shape change during osmosis and cell diffusion?
Osmosis effects the volume of a cell. when the cell has equal water molecules in the water aroung it and in the cell it is shaped normally. When there is a lot of salt in the water the cell shrinks because there is less water content in the salty water thus the cell gets rid of the extra water molecules. When there is very little salt content in the water the cell gets bigger because the cell absorbs to much water.
Do large cells and small cell carry out diffusion and osmosis at rate?
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.
Why aren't simple diffusion osmosis and filtration sufficient to supply the needs of the cell?
Simple diffusion, osmosis, and filtration are passive processes that rely on concentration gradients for movement of substances. They may not be sufficient to supply the needs of the cell because they are limited by the size, charge, and solubility of molecules as well as the need for specific transport mechanisms for certain molecules like glucose or ions. Cells require more complex and specific mechanisms such as active transport, endocytosis, and exocytosis to regulate the movement of molecules in and out of the cell to meet their diverse metabolic demands.
What cellular structure is the dialysis tubing representing in this lab?
The dialysis tubing in the lab is representing the cell membrane of a cell. Like the cell membrane, the dialysis tubing is selectively permeable, allowing only certain molecules to pass through based on size and charge. This setup is used in experiments to study osmosis and diffusion, which are also important processes regulated by the cell membrane.
What are restrictions that limit cell size?
Cell size is limited by several factors, including the surface area-to-volume ratio, which affects the efficiency of nutrient uptake and waste removal. As cells grow larger, their volume increases faster than their surface area, making it challenging to sustain proper metabolic functions. Additionally, the diffusion of substances within the cell becomes less efficient in larger cells, further constraining size. Other factors include the structural integrity of the cell and the availability of resources.

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.
Why diffusion and osmosis limit the size of the cell?
Diffusion and osmosis are processes by which substances move into and out of cells. As cell size increases, the distance that substances must diffuse across also increases, making it harder for cells to efficiently exchange materials. Additionally, larger cells may struggle to maintain proper osmotic balance due to increased demand on their membrane and organelles.
What Word Goes in There As cell size goes effectiveness of diffusion and osmosis goes This drives the cells to stay small?
Surface area. As cell size increases, the surface area to volume ratio decreases. This decreased ratio makes it harder for nutrients and waste to diffuse in and out of the cell, driving cells to stay small for efficient diffusion and osmosis.
What things limit cell size?
DNA, Diffusion, and Surface Area to Volume Ratio.
How are water and nutrients transported through bryophytes?
In bryophytes, water and nutrients are transported through the plant by diffusion and osmosis. These plants do not have vascular tissues like xylem and phloem found in higher plants, so they rely on simple diffusion to move water and nutrients from cell to cell. This limits the size that bryophytes can grow to.
What variables are held constant in osmosis and diffusion?
In osmosis, the concentration gradient, temperature, pressure, and size of the particles are typically held constant. In diffusion, the concentration gradient, temperature, size of the particles, and medium in which diffusion is occurring are commonly kept constant.
