Eukaryotic Cell Structure Flashcards
Cell Wall
Rigid outer layer made of cellulose; maintains cell shape and protects from mechanical damage
Plants & VULM
Cell Membrane
Flexible phospholipid bilayer; selectively permeable barrier between inside and outside of cell
Animal+Plant & VULM
Cytoplasm
A semi fluid containing dissolved substances in which other organelles + components are found
Animal+Plant & VULM
Nucleus
Contains DNA and genetic material; directs all cellular activity
Animals+Plants & VULM
Ribosomes
Translates genetic material
Animal+Plant
Endoplasmic Reticulum (Rough)
Interconnected tubes and flattened sacs connected to nucleus; studded with ribosomes; packages and transports secretory proteins
Endoplasmic Reticulum (Smooth)
Interconnected tubes and flattened sacs connected to nucleus; not studded with ribosomes; synthesizes lipids and packages them for transport to other parts of cell
Golgi Apparatus
Flattened membranous sacs that receive transport vesicles from E.R; E.R products are modified and stored, then sorted, repackaged and shipped
Animals+Plants
Lysosomes
Membranous sacs containing digestive enzymes within acidic environments; Breaks down food particles, kills infectious microorganisms and recycles worn out or damaged cell parts
Animals
Vacuoles
Membrane bound sacs used for storage; Plants have central vacuole
Animals+Plants
Mitochondria
Two membranes, inner highly folded; where cellular respiration occurs to generate energy (ATP)
Chloroplasts
Two membranes, flattened membranous sacs with green pigment molecules, chlorophyll; where photosynthesis occurs
Plants
