(40 cards)

Chemotaxis

Front

Movement in response to chemicals

Back

Bacillus

Front

Rod shaped

Back

Prokaryote

Front

-one circular chromosome -no membrane bound organelles -no nucleus -produce by binary fission (asexual) -peptidoglycan cell walls

Back

Hypotonic

Front

water moves into the cell, cell bursts

Back

Simple diffusion

Front

Movement of a solute from an area of HIGH concentration to area of LOW concentration (Down the gradient)

Back

Osmosis

Front

The movement of water across a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

Back

Penicillin

Front

Inhibits peptide bridges in peptidoglycan

Back

Flagella

Front

-outside cell wall -made of hollow proteins -anchored to the wall and membrane by the basal body

Back

Cell membrane

Front

Phospholipid bilayer

Back

Exocytosis

Front

Vesicle fuses with the plasma membrane on the inside and releases it outside (requires energy)

Back

Staph

Front

Clusters/ think grapes!

Back

Phagocytosis

Front

Pseudopods extend to engulf particles

Back

Endocytosis

Front

Plasma membrane surrounds substances from outside the cells and takes them in through a vesicle (requires energy)

Back

Facilitative diffusion

Front

Solute combines with a transporter protein in the membrane

Back

Spirillum

Front

Wavy

Back

Isotonic

Front

No movement of water, equilibrium

Back

Coccus

Front

Circular/sphere

Back

Fluid mosaic model

Front

-Membrane is viscous (like olive oil) -proteins move to function

Back

Phototaxis

Front

movement in response to light

Back

Capsule

Front

-neatly organized glycocalyx -prevent phagocytosis

Back

Eukaryote

Front

-paired chromosomes -membrane bound organelles -nucleus -cell wall made of polysaccharides -reproduce sexually or asexually

Back

Osmotic pressure

Front

Pressure needed to stop movement of water across the membrane

Back

Endosymbiotic theory

Front

Eukaryotic cells may have evolved when multiple cells joined together in one

Back

Spirochete

Front

Corkscrew

Back

Gram positive cell wall

Front

-thick peptidoglycan -teichoic acids

Back

Fimbriae

Front

Allows attachment to surfaces

Back

Evidence of endosymbiotic theory

Front

-Chloroplasts are same size as prokaryotic cells and have similar behaviors -mitochondria are same size ... " "

Back

Selective permeability

Front

Allows passage of some molecules

Back

Pilli

Front

Used to transfer DNA from one cell to another

Back

Lysozymes

Front

Digest disaccharide in peptidoglycan

Back

Peptidoglycan

Front

-polymer of disaccharide -liked by polypeptides (many amino acids)

Back

Haloarcula

Front

Square shaped

Back

Cell wall

Front

-prevents osmotic lysis -made of peptidoglycan

Back

Gram negative cell wall

Front

-thin peptidolycan -no teichoic acids -outer membrane of LPS

Back

Strep

Front

Chains

Back

Pinocytosis

Front

Membrane folds inward bringing in fluid and dissolved substances

Back

Active transport

Front

Requires transporter protein and ATP energy

Back

Stella

Front

Star-shaped

Back

Hypertonic

Front

Water moves out of the cell, cell shrinks

Back

Endosymbiont

Front

One organism that lives inside another one

Back
