Key Words

cell theory, prokaryotic, eukaryotic, Domain, Kingdom, Archaea, Archaebacteria, Bacteria, Eubacteria, Eukarya, Protista, Fungi, Plantae, Animaliae, cell membrane, cytoplasm, organelles, nucleus, nucleoid, cell wall, cytosol, ribosomes, nuclear envelope, nuclear pore, mitochondria, chloroplast, endomembrane system, rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus, lysosomes, vacuole, peroxisomes, Endosymbiont Theory

 

After studying cell structure, you should be able to:

1.  Distinguish between prokaryotic and eukaryotic cells with regard to

     a. the cellular components of each

     b.  the types of organisms that possess each cell type

2.  Recognize the structure and give a function for the following cellular components:

     plasma membrane                mitochondria                 vacuole

     cell wall                               chloroplast                    nuclear pore

     nucleoid                               Golgi apparatus            peroxisomes

     nucleus                                rough ER                      lysosomes

     nuclear envelope                  smooth ER                   ribosomes

3.  Be able to draw and label the components of a bacterial cell, an animal cell, and a plant

     cell.

4.  Be able to explain the Endosymbiont Theory for the evolution of eukaryotic cells
