Biology 34: Organismal Physiology
Section I: Thermodynamics and Plant Cells
A. Plant Cells
2. Prokaryotes vs. Eukaryotes
Prokaryotes are those organisms that do not have a nucleous. The term prokaryotic can be broken down into "pro" which means "before", and "karyon" which means kernal or nucleus. Not only do prokaryotes not have a nucleus, but they also do not have membrane bound organelles within the cytoplasm. However, Prokaryotes and Eukaryotes have ribosomes. Eukaryotes, on the other hand, do have membrane bound organells.
3. Cell Walls
Cell walls are one of the defining components of the plant cell. The cell wall supports the plant cell with the help of the vacuole. Animals do not have cell walls - How are animal cells supported?
4. Eukaryote Protoplasts
The eukaryote protoplast can be divided into three components: the cytoplasm, the nucleous, and the vacuole.
