,CELL STRUCTURE
The cells of eukaryotes contain a nuclei, cell
membrane and cytoplasm.
Most eukaryotic cells contain specialized
structures called organelles that perform
cellular functions.
Some eukaryotes live as single-celled
(unicellular) organisms but many are large
(multicellular) organisms.
The size and shapes of cells are related to the
functions they perform.
