An Overview of Eucaryotic Cell Structure Eucaryotic cells have membrane-delimited nuclei In addition to the nucleus, eucaryotic cells have other membrane-bound organelles that perform specific functions within the cells; this allows simultaneous independent control The large membrane surface area of eucaryotic cells allows greater respiratory and photosynthetic activity The Cytoplasmic Matrix, Microfilaments, Intermediate Filaments, and Microtubules The cytoplasmic matrix, although superficially featureless, provides the complex environment required for many cellular activities Microfilaments (4 to 7 nm) may be scattered throughout the matrix or organized into networks and parallel arrays; they play a major role in cell motion and cell shape changes
