7.3.1. Fluid mosaic model (6-31)
7.3.2. Phospholipid structure (6-32)
7.3.3. Cholesterol in membrane (6-33)
| binds to and immobilizes phospholipids (makes membranes less fluid and stronger) |
7.4.1. Diffusion

7.5.6. Exocytosis (tear fluid) (6-46)
8.1. How does surface/volume ratio influence cell metabolism and growth rates? Compare the s/v ratios of a sphere, cube, and oblong cell with the same volume.
8.2. What are the differences in the structures of viruses, prokaryotic, and eukaryotic cells? What is the cell type of a bacterium, archean, bluegreen alga, green algae, protozoan, fungus, higher plant, and higher animal?

DICTIONARY OF CELL BIOLOGY - SEARCH - J.A.T. Dow, Academic Press, London The Dictionary of Cell Biology was first published in 1989, and it is intended to provide quick access to easily-understood and cross-referenced definitions of terms frequently encountered in reading the modern biology literature. There are 5450 entries and 5772 cross-references.
