  • Front
  • Back
Nucleus
Contains chromatin and surrounded by a membrane
Ribosomes
Makes proteins, attached to rough ER or free in cytoplasm
Endoplasmic Reticulum
Creates and transports cell membrane proteins
Golgi Body
Sort proteins and lysosomes into vesicles
Vesicles
Store, transport, or digest cellular products or waste
Mitochondria
Site of cellular respiration in cell
Chloroplasts
Site of photosynthesis in plant cells
Lysosomes
Contain hydrolytic enzymes to digest macromolecules
Centrioles
Microtubular structures that make up the centrosome; important in cell division
Vacuoles
Membrane-bound compartments that have secretory, excretory, and storage functions
Motility
Flagella, cilia
Cytoskeleton
Made of microtubules, intermediate filaments, microfilaments
Cell wall
Creates rigid structure in plant cells and protects cell
Cell junctions
Desmosomes, tight junctions, and gap junctions in animal cells; plasmodesmata in plant cells
Cell membrane fuction
Movement of materials
Selectively permeable membrane
Membrane chooses what can and cannot pass through membrane
Diffusion
Movement of particles from high to low
Osmosis
Diffusion of water across cell membrane
Facilitated diffusion
Movement of particles from high to low with the help of proteins
Active transport
Transport of substances across a membrane using energy (ATP); from low to high
Hypertonic cell
Membrane is shrunken in, cell parts are shrunken
Hypotonic
Animal-cells swell and burst
Plant-normal state for cells
Isotonic
Equal solute concentrations inside and outside of cell
Plasmolysis
Contraction of cell membrane due to loss of water in cell
Vesicle transport
Exocytosis, endocytosis, phagocytosis, pinocytosis
Exocytosis
Release of large molecules through membrane
Endocytosis
Intake of large molecules through membrane
Phagocytosis
Cell "eating", Absorbtion of large molecules through membrane
Pinocytosis
Cell "drinking", absorbtion of small particles through membrane
Cellular Respiration
Carbon six Hydrogen twelve Oxygen six plus 6 O2 . 6 Carbon Oxygen two plus 6 Hydrogen two Oxygen plus energy
