internal membrane system found in eukaryotic cells, place where lipid components of the cell membrane are assembled
organelle in cells that modifies, sorts, and packages proteings and other materials from the endoplasmic reticulum for storage in the cell or released outside of the cell.
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it to chemical energy
cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cells to use.
