CELL DIVERSITYA cell’s shape reflects its function

Cellular OrganizationIn multicellular eukaryotes, cells organize into tissues, organs, organ systems, and finally organisms.

UNICELLULAR ORGANISMS

BACTERIA PROTOZOA

CONSIST OF ONLY ONE CELL

MULTICELLULAR ORGANISM

ORGANISM MADE OF MANY CELLS

PROKARYOTIC VS EUKARYOTIC

PROKARYOTIC Lack membrane-

bound organelles and nucleus

Genetic information in a Nucleoid

Simple Unicellular organisms Classified into two

domains Bacteria – E. Coli

EUKARYOTIC Has membrane-bound

nucleus and organelles Genetic Information in

the Nucleus Complex Multicellular Organisms Classified into one

domain White blood cells

PROTEIN SYNTHESIS

THREE MAIN PARTS OF THE CELL

1. Plasma Membrane

2. Control Center

3. Cytoplasm
