Nucleus ANS Control center of the cell, which is vital for protein synthesis
Control center
Contains all the cell DNA (except for DNA in mitochondria)
Nuclear envelope
Nuclear pores
DNA
Chromatin (condenses into chromosomes during prophase of mitosis)
RNA synthesis
Messenger
Ribosomal
Transfer
Nucleolus
Cytoplasm ANS Cell work occurs here
Water, electrolytes, proteins, fats and glycogen
Cell Membrane ANS Separates intracellular and extracellular environments
Provides receptors for hormones and other substances
Electrical activity between nerve and muscle cells
Aids in cell growth/proliferation
Provides receptors for hormones and other biologically active substances
,Participates in the electrical events that occur in nerve and muscle cells
Aids in the regulation of cell growth and proliferation
Ribosomes ANS Site of protein synthesis
Endoplasmic Reticulum ANS System of paired membranes
Rough and Smooth
Golgi Complex ANS Modifies and packages substances from ER
Mitochondria ANS Power house of the cell (energy), also function to regulate apoptosis
Lysosomes ANS Metabolism
Cytoskeleton ANS Microtubules
Develop and maintain cell form
