This document summarizes key aspects of cell theory. It outlines that all living things are made of cells, which arise from pre-existing cells and are the smallest living units. There are two main types of cells - prokaryote cells, which lack a nucleus and organelles, and eukaryote cells, which have a distinct membrane-bound nucleus. While prokaryotes are unicellular and have circular DNA, eukaryotes can be multicellular and have linear DNA. The document also notes differences and similarities between animal and plant cells.

2. CELL THEORY
 CELLS ARISE FROM PRE-EXISTING CELLS
 ALL LIVING THINGS ARE MADE-UP OF CELLS
 CELLS ARE THE SMALLEST LIVING THINGS

3. TWO MAIN TYPES OF A CELL
 PROKARYOTE CELLS
ARE ORGANISMS WHOSE CELLS LACK A NUCLEUS
AND OTHER ORGANELLES.
EUKARYOTE CELLS
ARE MULTICELLULAR ORGANISMS WHOSE CELLS
CONTAIN DISTINCT, MEMBRANE-BOUND
NUCLEUS.
