Cell Size

Paper Summary:

The cell engulfs food oxygen and lets out carbon dioxide yet everything must go through the cell membrane which is also the total surface area of the cell. This paper discusses metabollic processes within the cell and how these processes affect the cell's size.

From the Paper:

"The nucleus and cytoplasm use oxygen and food while producing waste through volume and weight. At times, the cell needs more membrane space in order to provide greater area for intake of oxygen and food and to release waste. However, as the cell grows larger, the ratio of the total surface area-weight ratio decreases. In other words, the greater cell content needs more oxygen and food than the membrane can take in and produces more waste than the membrane can release; its hydrophobic interior excludes the aqueous solutions of the cytoplasm and the external environment. "Although a large cell would be able to withstand more metabolic reactions (due to its larger volume) than a smaller cell, the larger..."
