What else can I help you with?
what Plant cells often have smaller surface-to-volume ratios than animal cells. How do the plant cells overcome this issue?
Plant cells overcome the issue of smaller surface-to-volume ratios with the help of the central vacuole. The vacuole pushes the organelles and other cellular materials toward the outer edges of the cell
What is the microscopic level of relationship between form and function exemplified by?
Cellular receptors exist only on the outer surface of the plasma membrane
What is the formula for surface area of pipe?
2*pi*r*L where r is (outer) radius of the pipe (in case of the outer surface) nd L is the length of the pipe.
How do you work out the outer surface area of a cube?
The answer depends on what information you have about the cube. If, for example, you know the volume, V, then the surface area is 6*cuberoot(V)^2. If you have the lengths of an edge, s, then it is 6*s^2.
What does the surface area mean?
the area of such an outer part or uppermost layer
What is the area to cell's outer surface in relationship to it's volume?
The surface-area-to-volume-ratio

What happens to the surface area to volume ratio when folds are made in a cell's outer membrane?
The surface area to volume ratio increases when folds are made in a cell's outer membrane. This increase allows for more efficient exchange of materials with the surroundings because there is more surface area available for interactions.
What do cells used bring in food and get of rid of water?
the outer surface :)
What cells cover the outer surface of the CNS?
The cells that cover the outer surface of the central nervous system (CNS) are called meningeal cells. These cells make up the three layers of meninges - the dura mater, arachnoid mater, and pia mater - that provide protection and support to the brain and spinal cord.
What are the properties of a hollow cylinder with respect to its volume and surface area, and how does the presence of the keyword "j" relate to these properties?
A hollow cylinder has a volume that is the difference between the volume of the outer cylinder and the inner cylinder. The surface area of a hollow cylinder is the sum of the surface areas of the outer and inner cylinders, plus the surface area of the two circular ends. The presence of the keyword "j" does not directly relate to the properties of a hollow cylinder.
Why are most cells small?
The surface area to volume ratio of a cell is important in order to pass materials the cell needs to survive across its surface. There is therefore an optimal size for a cell where it is large enough to hold all its internal structures and yet small enough for cross membrane transport. Any bigger than this and the cell will not be able to get enough nutrients into itself to live and function properly. Thus most cells are of this size (there are specific exceptions). ======================= There is a reason why cells are so small. Cells take in food and get rid of wastes through their outer surface. They need to have a large ratio of surface area to volume. Cells also don't have enough organelles to get the food through out the whole cell. ======================= They need to have a large ratio of surface area to volume ======================= Cells are small because they take in food and remove wastes through it's membrane(skin), so if it's surface area cannot take in enough food for it's volume, the cell can starve/poisen itself, which is why cells cannot be very big. (as an object gets bigger, so does it's volume and surface area. However, volume grows much faster, and if the object gets too big, the volume will exceed the surface area) ======================== The reason why cells must be so small is because cells need enough surface area to export and import all that they need. If they were too big they would not be able to carry out all the things that they do. ======================== Cells need to be small in order to have good surface area to volume ratios. It is important that the surface area be larger than the volume so that the things that need to get in and out of the cell can do so. Otherwise the cell could be poisoned by accumulation of waste or not being able to take in what it needs.
Outer surface layer of cells of a plant or animal?
The outer surface layer of cells in plants is called the epidermis. In animals, the outermost layer of cells is called the epithelium. Both serve as protective barriers, regulate the exchange of substances, and provide a first line of defense against pathogens.
Surface area to volume ratio example?
How does the surface-to-volume ratio change each time you cut the value of "s" in half? 4mm 96mm2 64mm3 1.5 to 1 2.0mm 24mm2 8mm3 3 to 1 1.0mm 6mm2 1mm3 6 to 1 0.50mm 1.5mm2 .125mm3 12 to 1 0.25mm .375mm2 .016mm3 24 to 1
What is an epithlium?
The term refers to cells that line hollow organs & glands & those that make up the outer surface of the body.
What is the relationship between the electric field and surface charge at a conductor?
The electric field inside a conductor is zero, and the surface charge resides on the outer surface of the conductor. This means that the electric field at the surface of a conductor is perpendicular to the surface and proportional to the surface charge density.
What is the microscopic level of relationship between form and function exemplified by?
Cellular receptors exist only on the outer surface of the plasma membrane
