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
