CYTOPLASM - the eukaryotic definition is cell substance inside the plasma membrane but  outside the nucleus. In many ways eukaryotic cytoplasm is similar to prokaryotic cytoplasm, but  one difference is that eukaryotic cells have a complex internal structure called a cytoskeleton,  made of three kinds of protein filaments: 1. Microfilaments 2. Intermediate filaments 3. Microtubules The cytoskeleton provides support and shape, as well as assisting in transport within the cells.  ORGANELLES --specialized structures within cells that have distinct functions and specific  shapes. 1. NUCLEUS - characteristic of eukaryotic cells, it is the largest organelle and contains the DNA.  The nucleus is surrounded by a double-layered membrane, the nuclear envelope. This membrane  has tiny openings called nuclear pores, which allow large molecules to enter and leave the  nucleus. While the cell is not dividing, the DNA molecules and associated proteins form a
