cell wall
|
a layer of material, normally made up of cellulose, that is outside the plasma membrane of plants, fungi, backeria and some protists. it protects, supports cell
|
|
plasma membrane
|
isolates cell contents from environment, regulates movement of materials into and out of cell, communicates with other cells
|
|
gentic material
|
encodes information needed to contsruct cell and control cellular activity (dna)
|
|
chromosomes
|
contain and control use of dna
|
|
nucleus
|
membrance bound container for chromosomes/genetic material
|
|
nuclear envelope
|
double membrance system surrouding that encloses nucleus of eukaryotic cells; regulates movement of materials into and out of nucleus
|
|
necleolus
|
synthesizes components of ribosomes
|
|
mitochondria
|
has double membrane - extracts energy from sugar molecules and stored in ATP bonds - produce energy by aerobic metabolism
|
|
chloroplasts
|
the organelle in plans and plantlike protists that performs photosynthesis, surrounded by a double membrane
|
|
ribosomes
|
provide site of protein synthesis
|
|
smooth endoplasmic reticulum
|
provides site for molecules (such as phospholipids and choloesteral ) to be packaged and shipped elsewhere in the cell
|
|
rough endoplasmic reticulum
|
series of interconnected membrane encolsed channels in the cytoplasm - has embedded ribosomes and provides sites wehre proteins are manufactured
|
|
golgi complex
|
a stack of membranous sacs, found in most eukaryotic cells, that is the site of processing and separtion of membrance components and secretory materials - modifies and packages proteins and lipids, synthesizes carbohydrates - used as transfer station for substances
|
|
lysosomes
|
organelle containing digestive enzymes
|
|
central vacuole
|
a large, fluid filled vacuole occupying most of the volume of many plant cells - helps keep the right amount of water in the cell and provides a dump site for hazardous waste
|
|
cytoskeleton
|
a network of protein fibers in the cytoplasm that gives shape and support to cell; positions and moves cell parts
|
|
centrioles
|
synthesize microtubules of cilia and flagella
|
|
cilia and flagella
|
move cell through fluid or move fluid past cell surface
|
|
cytoplasm
|
material inside plasma membrane where most of the cells metabolic activies occur
|
|
nucleoid region
|
holds dna in prokaryotic cells
|
