Ati Teas 7 Science Biology
cell wall -
strong, supporting layer in plant cells
Cytoskeleton -
Protein filaments that helps the cell to keep its shape, and aids in movement
Flagella (cilia) -
movement of cell
plasma membrane -
A selectively-permeable phospholipid bilayer forming the boundary of the cells
Endoplasmic Reticulum -
Rough ER has ribosomes synthesize proteins and Smooth ER has no ribosomes
synthesize lipid
Nucleus -
Control center of the cell
Golgi apparatus -
Packages proteins for transport out of the cell and forms secretory vesicles
Lysosomes -
An organelle containing digestive enzymes
Microbodies -
Isolate particular chemical activities from rest of cell
Mitochondria -
Powerhouse of the cell (ATP)
Chloroplast -
Site of photosynthesis
Chromosomes -
threadlike structures made of DNA molecules that contain the genes
Nucleolus -
produces ribosomes
Ribosomes -
Makes proteins
Cytoplasm -
A jellylike fluid inside the cell
1|Page
, Eukaryote -
A cell that contains a nucleus and membrane bound organelles
Prokaryote -
A unicellular organism that lacks a nucleus and membrane bound organelles
Phospholipids -
A molecule that is a constituent of the inner bilayer of biological membranes,
having a polar, hydrophilic head and a nonpolar, hydrophobic tail.
phosphatides -
fatty acid esters of glycerol phosphate with a nitrogen base linked to the
phosphate group
integral proteins -
penetrate the hydrophobic interior of the lipid bilayer
Glycoproteins -
A protein with one or more covalently attached carbohydrates.
channel proteins -
provide corridors that allow a specific molecule or ion to cross the membrane
carrier proteins -
Move materials by active or passive transport
peripheral proteins -
Protein appendages loosely bound to either side of the membrane and act as
enzymes or receptor proteins
Osmosis -
Diffusion of water through a selectively permeable membrane
Hypertonic -
Higher solute concentration; net flow of water is OUT of cell
Hypotonic -
Lower solute concentration; net flow of water INTO the cell cause it to SWELL
Isotonic -
same solute concentration; move in and out of cell at equal rates
passive transport -
the movement of substances across a cell membrane without the use of energy by
the cell
facilitated diffusion -
Proteins transport substances down concentration gradient
active transport -
