Paul Andersen takes you on a tour of the cell. He starts by explaining the difference between prokaryotic and eukaryotic cells. He also explains why cells are small but not infinitely small. He also explains how the organelles work together in a similar fashion.
Paul Andersen describes the structure and function of the major organelles in a eukaryotic cell. The endoplasmic reticulum, ribosomes, and golgi complex produce and store proteins in the cell. Lysosomes dissolve broken and invasive material. Vacuole store material in plant cells. Mitochondria produce ATP through cellular respiration and chloroplasts use the energy of the sun to produce sugars.
Crash Course Biology #5 - Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

Things you should make sure you understand:
(feel free to ask questions about them in class)
- The structure and function of cillia and flagella.
- The structure and functions of the three major components of the cytoskeleton (microfilaments, microtubules, and intermediate filaments).
- Why particular substances will or will not be able to pass through the phospholipid bi-layer of the cell membrane.
- How membrane-protein structure can allow for portions of the protein to be embedded in the membrane AND allow portions to extend in to and out of the cell.
- The structure and function of the cell wall.
- The structure and function of the extracellular matrix.
- The differences in structure and function among the types of intercellular junctions found in cells (tight junctions, gap junctions, desmosomes, and plasmodesmata)
