Card Set Information
structure:2 layers of phospholipids with protein molecules.
fcn:Forms outer boundary of cell, regulates movement of materials in and out of cells.
General term for the material located inside the plasma membrane and outside the nucleus.
: Made up of two parts:cytosol and organelles
Double membrane structure, outer membrane stretched, inner folded
: Major ATP production
Consists of saccules. Usually 5-6
fcn:Synthesis of pacaging of secretions for release outside the cell.
Renewal and modification of plasma membrane
Packaging of enzymes with vesicles for use in cytoplasm
Network of intercellular membranes forming flatened sacks, tubes, cisternae
synthesis, storage, transport, detoxification
An internal protein framework in a cytoplasm
fcn:Gives the cytoplasm strength and flexibility
Dense granules composed of RNA and protein
: sites of protein synthesis
large often sphereical structure, prominent structure.
: carries hereditary info
directs of the activities of cells
Similar to plasma membrane except
-pores are larger
fcn:seperates nuclear contents from the cytoplasm
: Dark Staining areas
: assembly sites for ribosomes
single membrane structure
: contains hydrolytic and digestive enzymes
found only in animal cells
composed of 9 triplets
: forms the poles of the spindle that develops during the cell division
Cilia and Flagella
9 +2 arrangement of microtuble
found in cells and plants
rigid non living material
protection and support
Double membrane plastid containing chlorophyll
IN PLANT CELLS
Cytoplasmic channels connection adjacent plant cells
Intercellular exchange of small molecules and ions
Very thin proteoglycan layer between opposing cell membranes that is reinforced by intermediate fibers.
very strong and resist stretching.
Caused by fusion of lipid portions of two cell membrances
fcn:keep material from leaking through tissues
2 cells held together by interlocking membrane proteins
fcn:these are channel proteins; so form a passageway that lets small molecules and ions pass from cell to cell
