Which cells function more efficiently? Large or small cells?
Small Cells-can exchange substances more readily than large cells because small objects have a higher surface area to volume ratio than larger objects. Substances do NOT need to travel as far to reach the center of a smaller cell.
OUTER boundary of cell--it encloses the cell and separates the cell interior; regulates what enters and leaves a cell
inside cytoplams are many structures-often suspended in a system of microscopic fibers called a cytoskeleton Includes everything inside the cell membranes but OUTSIDE the nucleus
within the cytoplasm-a system of microscopic fibers
