Guide. A bone density test measures the density of minerals (such as calcium) in your bones using a special X-ray. This information is used to estimate the strength of your bones.
Animal cells do have vacuoles, but they are smaller, larger in number (plant cells usually have just one or a few large vacuoles) AND serve a somewhat different purpose than those of plants.
Vacuoles can be found in plant cells, although the plant cell only has one vacuole. A vacuole stores water, food, and enzymes, and collects unwanted waste. A vacuole is a sac â¦ used to store water for the cell.Plant cells have a large vacuole. Animal cells have small vacuoles, if they have one at all. A vacuole maintains the acidic internal pH and also the turgor and hydrostatic pressure in the cells.acuoles are water-filled storage spaces found in cells. They are found in both animal and plant cells (but they are more common in plant cells they are also bigger in plant c â¦ ells). Vacuoles store food, collect waste products, and can help with cell shape and buoyancy.
