Plasmodesmata

Plasmodesmata joins internal chemical environments of adjacent cells and makes plant into one living continuum

Desmosomes

Rivets, fasten cells together with keratin protein, microfilaments anchor desmosomes in cytoplasm. Attach muscle cells.

Fractionation

Used to isolate cell components based on size and density. Enables researchers to prepare specific cell components in bulk and identify their functions.

ECM

Complex network of macromolecules, glycoproteins and minerals that provide structural and biochemical support to surrounding cells.

Microvilli

Projections that increase the cell’s SA

Gap junctions

Cytoplasmic channels from one cell to adjacent cell. Communicates because small molecules can pass through

Smooth ER

Storage, detox, metabolism of carbs

Rough ER

Aids in synthesis of secretory and other proteins from bound ribosomes, adds carps to proteins to make a glycoprotein, produces new membrane

Microfilaments

Muscle contraction

Centrosome

Region where the cell’s microtubules are initiated. Contains a pair of centrioles.

Microtubules

Cell division, near the centrioles, provide mechanical support against compression

Intermediate filaments

Bear tension, support the cell against physical stress

Tight junctions

Prevents extracellular fluid from leaking
