Cell Membrane Protective outer covering of the cell “semi-permeable” Allows certain substances to go in and out of the cell 

Cell Wall found in plant cells & bacteria only Supports & protects cells Gives its shape Made up of lignin and cellulose

Inside the Cell

Nucleus Directs cell activities Contains genetic material - DNA

Nuclear Membrane Surrounds the nucleus Made up of two layers Openings allow material to enter and leave nucleus

Chromosomes In nucleus Made up of DNA Contain instructions for traits & characteristics

Nucleolus Inside nucleus Contains RNA to build proteins

Cytoplasm Gel-like mixture Surrounded by cell membrane Contains hereditary material Where organelles are found
