, Cell Theory: All living organisms
are made of cells, and all cells
Overview: arise from pre-existing cells.
1. Introduction to the Cell 2. Organism Types
Definition:The cell is the basic
structural, functional, and
biological unit of all living Unicellular Organisms:
organisms. Often called the Organisms made of a single cell
"building blocks of life," every that perform all life functions (e.g.,
living thing—from tiny bacteria to Amoeba, Paramecium).
large animals—is composed of
cells.
Multicellular Organisms:
Organisms composed of many
Discovery: Robert Hooke
cells that often work together in
discovered cells in 1665 while
specialized groups
observing a thin slice of cork
(tissues/organs) to perform
under a microscope; he saw
specific functions (e.g., humans,
honeycomb-like structures and
trees).
named them "cells".
