Cell WallOuter layer of plant cellsRigid & strongMade of celluloseFunctions:Support (grow tall)Protectionallows H2O, O2, CO2 to diffuse in & out of cell
Menu
IncorrectThe nucleolus is the mini nucleus or the inner part of the nucleus which is responsible for making ribosomesClick to go back
Nucleus Large, ovalMay contain 1 or more nucleoliHolds DNAFunctions:Controls cell activitiesContains the hereditary material of the cell
Menu
CytoplasmClear, thick, jellylike material (cytosol)Organelles found inside cell membraneContains the cytoskeleton fibersFunctions:Supports and protects cell organellesMenu
Endoplasmic Reticulum Network of tubes or membranesSmooth w/o ribosomesRough with embedded ribosomesConnects to nuclear envelope & cell membraneFunctions:Carries materials through cellAids in making proteins
Menu
Golgi Apparatus Stacks of flattened sacsFunctions:Have a cis & trans faceModify proteins made by the cellsPackage & export proteins
Menu
RibosomesSmall bodies free or attached to ERMade of rRNA & proteinFunctions:Synthesizes proteinsMenu
MitochondriaPeanut shapedDouble membraneOuter membrane smoothInner membrane folded into cristaeFunctions:Breaks down sugar (glucose) molecules to release energySite of aerobic cellular respiration
