Biology Chapter 4

ANIMAL CELL

NUCLEUS:

RIBOSOMES:

ENDOMEMBRANE SYSTEM: nucleus, nuclear envelope, endoplasmic reticulum, golgi, lysosomes, vesicles & vacuoles, plasma membrane

-carries out synthesis of proteins, transport of proteins, metabolism + movement of lipids, detoxification of poisons

VESICLES:(TRANSPORT)

GLYCOPROTEINS:

ENDOPLASMIC RETICULUM:(ROUGH AND SMOOTH)

GOLGI APPARATUS:

L

LYSOSOME:

Phagocytosis:process in which protists eat by engulfing smaller organisms 

VACUOLES:

MITOCHONDRIA:

CYTOPLASM:

CYTOSKELETON:

CELLULAR JUNCTIONS

ANIMAL CELL

Extracellular Matrix   Glycoproteins & carb-                 containing cells

PLANT CELL

CELL WALL:

PEROXISOMES:

CHLOROPLAST:

PROKARYOTIC CELL

Collagen- glycoprotein; forms strong fibers in outside cell 

Proteoglycans- small protein with carb chains covalently attached

Fibronectin- glycoprotein; bind to cell surface receptor proteins (integrins)

Integrin- receptor protein in plasma membrane

Tight Junctions

Seal adjacent epithelial cells 

Functions

1) prevent the passage of molecules and ions between cells -controls what substances are allowed through2) block the movement of integral membrane proteins -receptor mediated endocytosis and exocytosis can be preserved 

PLANT CELL

Plasmodesmata

-communication between plant cells -single living unit 

Gap Junctions

-communication

-communication

Desmosomes

"rivets" -hold two cells tightly together 

Eukaryotic Cell-Animal
