these cells are small and simple and lack a nucleus.
these are the largest of the protein fibers in the cytoskeleton. they form "tracks" for the organells to follow as they move htrough the cell.
this structure houses the DNA and protects it from potentially damaging reactions in the cytoplasm.
the series of interacting organells between the nucleus and the plasma membrane that makes lipids, enzymes, and proteins for secretion or insertion into cell membranes.
this structure controls substances passing in and out of the cell.
this semi-fluid occupies the space between the plasma membrane and the nucleus.
the general name for a structure that carries out a specialized function within a cell.
these allow cells to interact with each other and the enviornment
hydrophilic head on either side, hydrophobic inside.
clearly defined nucleus
surface to volume ratio
volume measures faster than the surface area.
small sack that holds DNA
membrane around the nucleus, is porus.
darkened area on nuclear envelope where ribosomes are made.
protein syntheses (factories)
has ribosomes attached, stores and modifies protiens made by the ribosomes.where 2-3-4 structures are formed
no ribosomes, stores and modifies carbohydrates + lipids, where the cell membrane is produced
small sacks that transport substances from organelle to organelle.
combines substances from sER to rER into complex substances. an assembly plant
sack that contains enzymes to break down organic molecules or bacteria.
sack that helps break down drugs
converts glucose to ATP
gap cell junctions
holes in cells that let chemicals move through to other cells
