thin, flexible barrier around a cell; regulates what enters and leaves the cell
strong supporting layer around the cell membrane in plants, algae, and some bacteria
one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
short hairlike projection similar to a flagellum; produces movement in many cells
cavity in the cytoplasm of some protists that collects water and discharges it from the cell

directions for inhertance carried by a molecule
internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified
tail like appendage used for locomotion of certain cells and or unicircular organism
stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
cell organelle filled with enyzmes need to break down certain materials in the cells
cell organelle that converts the chemical energy stored in foods into compounds that are more convenient for the cell to use
layer of two membranes that surrounds the nucleus of the cells
pores which allows materials to move in and out of the cell nucleus
small, dense region within most nuclei in which the assembly of proteins begins
small particles in the cell on which proteins are assembled; made of RNA and proteins
