Types of Cells

Cells can be divided into two distinct types. One group, the prokaryote cells, do not have a true nucleus and lack membrane-bound structures. The second group, the eukaryote cells, have both a nucleus and membrane-bound structures. Only bacteria have prokaryotic cells. All other organisms have eukaryotic cells.

There are also differences between plant and animal cells.

Plant Cell:

• Has cell membrane and cell wall.
• Has large vacuoles.
• Contains chlorophyll.

Animal Cell:

• Has cell membrane only.
• Has small vacuoles.
• Lacks chlorophyll.
