The Chemist and the Physicist would agree that it has a high density.
The rest of us would remark that it is a very dense substance.
Examples are gold, lead, stone, and my wife's matzoh balls.
"large density" ===> (relatively large mass) fits into (relatively small volume)
A small cell will have a larger surface-to-volume ratio.

Unless you have an extremely small house or an extremely large pencil a house has a greater volume than a pencil.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
"large density" ===> (relatively large mass) fits into (relatively small volume)
a small volume. Density is a measure of how much mass is contained in a given volume. Higher density means there is more mass packed into a smaller space.
A large cone has a greater volume than a small frustum while a small cone has a smaller volume than a large frustum
No, Density is directly proportional to mass; Density increases as the mass increases, density decreases when mass decreases. Density is inversely proportional to volume; Density decreases when volume increases, density increases when volume decreases.
You can't. The same mass can have a lot of different volumes, depending on the substance. Examples: A kilogram of stone or lead has a small volume. A kilogram of water has a medium volume. A kilogram of the air inside your house has a large volume.
Dense
Yes, the mass-to-volume ratio - commonly called the density - is a typical amount for any substance. For example, you can have a large block of lead, which is heavy, and a small block of lead, which is much lighter. But the density (mass-to-volume ratio) will be the same for both - about 11,000 kg/m3.
This situation could be an analogy for a substance with high density, where a large amount of mass is packed into a small volume. Just like the crowded elevator, the particles in a dense substance are tightly packed together.
Density is considered a characteristic property because it remains constant regardless of the sample size, whereas mass and volume can vary based on the size of the sample. Mass and volume are extensive properties that depend on the amount of substance present, whereas density is an intensive property that describes the relationship between mass and volume.
diffusion
Several small volumes is more effective.
A small cell will have a larger surface-to-volume ratio.
