Provide reasons for cells being so small
WebbCells shrink. If enough cells decrease in size, the entire organ atrophies. This is often a normal aging change and can occur in any tissue. It is most common in skeletal muscle, the heart, the brain, and the sex organs (such as the breasts and ovaries). Bones become thinner and more likely to break with minor trauma. WebbCells are small because the ratio of surface area to volume is the most efficient at their size. This is because when you have a lot of small objects vs a few big objects the …

Webb16 feb. 2024 · The direction that water moves is dependent upon the osmolarity of the solutions on either side of a semipermeable membrane. Water always moves from a region of low to high osmolarity. There are three terms used to describe tonicity when comparing two solutions: hypotonic, hypertonic and isotonic. Webbvolume = 4.2 μm3. r = 2 μm. surface area = 50.3 μm2. volume = 33.5 μm3. The surface-to-volume ratio of the smaller cell is 3, while the surface-to-volume ratio of the larger cell decreases to 1.5. Think of the cell surface as the ability of the cell to bring in nutrients and let out waste products.

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
