Chapter 01: Cellular Biology
This chapter covers many basics of cell biology that are prerequisite for the
course and that you should have already covered and learned from your
previous courses (most likely, you already know them). Please go through
these and make sure you have a general understanding of each.
Learning Objectives
After reviewing this chapter, the learner will be able to do the following:
1. Compare and contrast prokaryotes and eukaryotes.
eukaryotic cell consists of three general components: the plasma
membrane, the cytoplasm, and the intracellular organelles.
Eukaryotic cells contain membrane-bound organelles, such as the
nucleus, while prokaryotic cells do not. Differences in cellular structure of
prokaryotes and eukaryotes include the presence of mitochondria and
chloroplasts, the cell wall, and the structure of chromosomal DNA.
2. Identify the eight specialized functions of a cell.
movement, conductivity, metabolic absorption, secretion,
excretion, respiration, reproduction, and communication
3. Discuss the functions of the principal cytoplasmic organelles.
4. Discuss the plasma membrane addressing both structural and
functional aspects.
plasma membrane encloses the cell and, by controlling the
movement of substances across it, exerts a powerful influence on
metabolic pathways. Principles of membrane structure are being
overhauled.
Functional: surrounds organelle, control the composition of space, control metabolic pathways
in/out of cell, cell to cell recognition.
Structural: helps with fluid and electrolyte balance
-protection, storage, cell to cell interaction, outer surface contains areolae that serve as storage
site for many receptors, activation of cell-hormones (reg. of cell activity), mitogens (cellular
division), antigens (antibody synthesis), growth factors (proliferation & differentiation) *lipids
within are responsible for structural integrity of membrane*
5. Discuss the impo
