Structures And Functions Flashcards
Coating that surrounds some bacterial cells; loose gel-like structure that, in particular bacteria, helps protect against phagocytosis
-organized and firmly attached externally to the cell wall
-allows the cell to be more resistant and adhere to surfaces
Capsule
Plasma (cytoplasmic) membrane that lines the inside of the cell wall of many bacteria
-comprised of phospholipids and proteins
-encloses the interior structures of bacteria
-regulates the flow of material into and out of the cells
Cell membrane
Semirigid structure that provides the cell with it’s shape
-made mostly of peptidoglycan
-offers the cell protection and anchors appendages
Cell wall
Gel like matrix that contains cell structures
-mixture of water, enzymes, carbs, and lipids
-location of cellular function
Cytoplasm
Region in the cytoplasm that contains chromosomal DNA
Nuclear body (nucleoid)
Circular piece of extrachromosomal DNA that is involved in reproduction
Plasmid
Structure that assists in protein synthesis
Ribosome
Folded area of the plasma membrane that likely assists in DNA replication
Mesosome
Sticky coating surrounding the cell wall in prokaryotes
Glycocalyx
A thick-walled body produced by a bacterium to enable it to survive in unfavorable environments
-bacteria in a hibernation like state
-highly resistant casing that allows the bacteria inside to survive for thousands of years
-resistant to disinfectants
Endospore
Short, thin attachments that allow organisms to adhere to surfaces
-usually only one of two attach to a cell
-often allow bacteria to adhere to each other
Pili
Long whip-like appendages that propel and organism
Flagella
Bacteria are actively growing and reproducing
Vegetative
Bacteria are actively forming an endospore
Sporulating
