Who has bigger cells, a mother or a baby lion?
On average they are the same. Cells come in a wide variety of sizes, even within one organism RBC are 8um in diameter Nerve cells can reached up length to 1 meter long Largest cell is the ostrich yolk 8 cm in diameter CELL SIZE 1. A few types of cells are large enough to be seen by the unaided eye. The Female egg is the largest cell in the body, and can be seen without the aid of a microscope. 2. Most cells are visible only with a microscope. 3. MOST CELLS ARE SMALL FOR TWO REASONS: Cells are limited in size by the RATIO between their outer surface area and their volume. A SMALL CELL HAS MORE SURFACE AREA THAN A LARGE CELL FOR A GIVEN VOLUME OF CYTOPLASM. This is important because the nutrients, oxygen, and other materials a cell requires must enter through it surface. As a cell grows larger at some point its surface area becomes too small to allow these materials to enter the cell quickly enough to meet the cell’s need.
