If a cell cannot move enough material through its membrane to survive, it likely has a low surface area-to-volume ratio. As a cell increases in size, its volume grows faster than its surface area, leading to decreased efficiency in material exchange. This unfavorable ratio can hinder the cell's ability to obtain nutrients and remove waste, ultimately impacting its viability. Therefore, maintaining an adequate surface area-to-volume ratio is crucial for cellular function and survival.

vent
The opening at the surface of the Earth through which volcanic material passes is called a vent. Vents can vary in size and shape, and they are typically found at the top of a volcano or along a fissure during an eruption. Magma rises through the vent and erupts onto the surface as lava, ash, and gas.
A semi-permeable membrane can be created by using materials that allow certain substances to pass through while blocking others. This can be achieved by selecting a material with specific pore sizes or by modifying the surface properties of the membrane to control what can pass through.
cell membrane
One way to increase the speed of material movement through a cell membrane without taking up more space would be to incorporate more channels or transport proteins. These proteins can facilitate the movement of specific molecules across the membrane more efficiently. Another approach could be to increase the fluidity of the membrane by incorporating more unsaturated fatty acids, which would make it easier for molecules to move through the membrane. Lastly, increasing the surface area of the membrane through invaginations or microvilli could also enhance material transport.

"diffusion"
To increase material movement without taking more space, you could introduce more transport proteins in the membrane to facilitate faster movement of molecules. Increasing the fluidity of the membrane by incorporating more unsaturated fatty acids could also enhance diffusion rates. Finally, adding more microvilli or cilia on the cell surface would increase surface area for material exchange without increasing cell size.

the cell's surface area
The Plasma Membrane, which has a phospholipid bi-layer.
When light strikes a transparent surface, it can be transmitted through the material, absorbed by the material, or reflected off the surface. The amount of light that is transmitted, absorbed, or reflected depends on the properties of the material and the angle at which the light strikes the surface.
