Chapter 6 Kimberlyn
Endomembrane
Endoplasmic Reticulum
Golgi Apparatus
Lysosomes
Vacuoles
Nuclear Envelope
Plasma Membrane
Prokaryotic
No nucleus
DNA Inbound region called the "Nucleoid
No membrane-bound organelles
Cytoplasm bound by the plasma membrane
Eukaryotic
Membrane - Bound organelles
DNA in nucleus bounded by double mebrane
Cytoplasm in region between plasma membrane and nucleus
3 parameters microscopy
Magnification
Resolution
Contrast
Nucleus
Nucleus contains most of cell genes
Nuclear Envelope encloses the nucleus separating it from the cytoplasm
Nuclear Envelope is a double membrane
Ribosomes Build Proteins
On the outside of the endoplasmic reticulum
In the cytosol (Free Ribos)
Nuclear Envelope (Bound Ribos)
Smooth ER
Synthesizes Lipids
Detoxifies drugs and poisons
Stores calcium ions
Rough ER
Membrane factory for the cell
Trasnport vesicles
Has bound ribosomes, which secrete Glycoproteins
Golgi Apparatus
Modifies products of the ER
Manufactures certain Molecules
Sorts and packages materials into transport vesicles
Cytoskeleton
Microtubulus the thickets of the three components of the cytoskeleton
Microfilaments also called actin filaments are the thinnest componets
Intermediate filaments are fibers with diameter in a middle range
Plant Cell Walls
Primary cell wall
Middle lamella
Secondary cell wall
Microtubules
Shaping the cell
Guiding movement of organelles
Separating chromosomes during cell division
Three types cell junctions common in epithelial tissues
Tight junctions, membranes of neighboring cells are pressed together, preventing leakage of extracellular fluid
Desmosomes (anchoring junctions) fasten cells together into strong sheets
Gap junctions (communicating junctions) provide cytoplasmic channels between adjacent cells
Microscopy
(LM) visible light is pass through a specimen
(Bend) Light so image is magnified
Cell Fraction
Takes cells apart & operates them
Centrifuges fractionate cells into their component parts
Vacuoles
Large vesicles derived from the ER
Variety of functions in different kinds of cells
Eukaryotic Cells / Prokaryotic Cells
Eukaryotic cells are generally much larger than Prokaryotic cells
Protein Factories
Ribodomes are complexes made of ribosomal RNA & protein
Endoplasmic Reticulum
Accounts for more than half od the total membrane in many eukaryotic cells
Two Regions of (ER)
Smooth lacks ribosomes & Rough surfaces is studded with ribosomes
Mitochondria
cellular respiration metabolic process uses oxygen to generate ATP
Chloroplasts
Found in plants and algrea
