CHAPTER 5: Cell and organelles:
structure and function
Method for cell fractionation and observation
Cell fraction
Cell observing
Light Microscopy
Electron Microscopy (EM)
Cell size and scale
Surface Area
Animal
Plant
Cell type
Prokaryotic cell
DNA in an unbound region called the nucleoid
No membrane-bound organelles
No nucleus
Cytoplasm bound by the plasma membrane
Eukaryotic cell
Membrane-bound organelles
Cytoplasm in the region between the plasma
membrane and nucleus
DNA in a nucleus that is bounded by a
membranous nuclear envelope
generally much larger
than prokaryotic cells
CELL AND ORGANELLES

Strengthens tissues and transmits
external signals to cell
Intercellular Junctions (Animal cells)
Glycocalyx
