3 B) Two Types of Cells: 1) EUKARYOTIC CELLS: 2) PROKARYOTIC CELLS: These cells have a nucleus.Nucleus is a membrane covered organelle that holds the DNA.Examples are plant and animal cells.2) PROKARYOTIC CELLS:These cells DO NOT have a nucleus.DNA exists in loops that floats freely in the cell.An example is bacteria3
13 4) CYTOSKELETON 5) CELL WALL found in animal cells. it is a protein “framework” inside the cell that gives the cells their shape.5) CELL WALLfound in plant cells not animal cellsprovides strength and support for plant cells.made of cellulose (long chains of sugar molecules)13
