Chapter 6
endomembrane system
Nuclear envelope
Endoplasmic reticulum
Golgi apparatus
consists of flattened membranous sacs called cisternae
Modifies products of the ER
Manufactures certain macromolecules
Sorts and packages materials into transport vesicles
Lysosomes
Vacuoles
Food vacuoles
Contractile vacuoles
Central vacuoles
Plasma membrane
Prokaryotic cells
No nucleus
DNA in an unbound region called the nucleoid
No membrane-bound organelles
Cytoplasm bound by the plasma membrane
Eukaryotic cells
DNA in a nucleus that is bounded by a double membrane
Membrane-bound organelles
Cytoplasm in the region between the plasma membrane and nucleus
nucleus contains most of the dna, ribosomes use that info from dna to make protiens
three important parameters of microscopy :
Magnification
the ratio of an object’s image size to its real size
Resolution
the measure of the clarity of the image, or the minimum distance of two distinguishable points
Contrast
visible differences in brightness between parts of the sample
Three domains of life
Eukarya
membrane bound organelle
4 kingdomes
Plantae
anamalia
protista
fungi
Bacteria
prokaryotes
Archaea
prokaryotes
live in harsh environments
mitochondria and chloroplasts
change energy from one form to another
chloroplast structure includes:
Thylakoids
Stroma
basic features of all cells
Plasma membrane
Semifluid substance called cytosol
Chromosomes (carry genes)
Ribosomes (make proteins)
endoplasmic reticulum (ER)
two regions
Smooth ER
lacks ribosomes
Functions
Synthesizes lipids
Detoxifies drugs and poisons
Stores calcium ions
Rough ER
surface is studded with ribosomes
Functions
Has bound ribosomes, which secrete glycoproteins
Distributes transport vesicles, secretory proteins surrounded by membranes
Is a membrane factory for the cell
