Ch. 6: A Tour of the Cell All organisms are made of cells simplest collection of matter that can be alive Microscopy progressed the discovery and early study of cells Robert Hooke looked at dead cells from the bark of an oak tree Antoni von Leeuwenhoek ? intro to the world of microorganisms Cell fractionation takes cells apart and separates major organelles and subcellular structures from one another using a centrifuge Prokaryotic vs. Eukaryotic Euk: DNA is in the nucleus Pro: DNA is in the nucleoid (not enclosed by membrane) Eukaryotic cells are generally much larger Cytosol: semifluid portion of the cytoplasm Biological membrane: phospholipid bilayer with proteins embedded Nucleus contains most of the genes in the cell

6.2 Eukaryotic Cells I. Eukaryotic cells include animal, plant, protest, and fungi cells. Prokaryotic cells include bacteria and archaea. A. Eukaryotic vs Prokaryotic 1. SMILARITIES a. bounded by plasma membrane b. within membrane is a semifluid substance called cytosol in which organelles are found c. chromosomes ? carrying genes in form of RNA/DNA d. ribosomes ? tiny organelles that make proteins from genes 2. DIFFERENCES Eukaryote Prokaryote - Nucleus (chromosomes) - Nucleoid (but no membrane separates it from rest of the cell)

CHAPTER 6 A TOUR OF THE CELL Learning objectives: How We Study Cells Distinguish between magnification and resolution. Magnification is how large it appears, resolution is how clear. Describe the principles, advantages, and limitations of the light microscope, transmission electron microscope, and scanning electron microscope. Light Microscope: Visible light comes through the bottom up to the lens. Can magnify up to 1000x and study living cells, but cannot view smaller objects such as cell organelles.
