Mo3-L3b: The Types of Cells and the Function of their Structures

SUMMARY
The Types of Cells and the Functions of Their Structures

Cells can be grouped into two types—prokaryotic
cells and eukaryotic cells.

In a chloroplast, light energy is used for making
sugars in a process called photosynthesis.
prokaryotic cell eukaryotic cell

A defining feature of a prokaryotic cell is that the (1.)
material is not surrounded by a(n) (2.) Another characteristic
of prokaryotic cells is that they do not have all the (3.)
found in eukaryotic cells. Most prokaryotic cells are one-celled, or(4.)
organisms and are called (5.) .
