Introduction to the Cell Cell Theory, Prokaryotes and Eukaryotes
Cell Theory All organisms are made of one or more cells Cells are the basic units of structure and function of all organisms New cells are produced from existing cells when they divide
Prokaryotic Cells (prokaryotes) Simplest type of cell – found in bacteria Small size – between 1 – 10 microns Does not have a nucleus Does not have membrane bound organelles
Eukaryotic Cells (eukaryotes) Complex cell structure – found in protists, animals, plants and fungi Large size – between 10 – 100 microns Has a nucleus Has membrane bound organelles
Today’s Objectives TSW distinguish between plant and animal cells and diagram them. TSW distinguish between prokaryotes and eukaryotes.
LN# 8 Cells.
What is a cell? It took a long time for people to discover cells and figure out what they were all about. They need sophisticated equipment (microscopes)
Prokaryotic and Eukaryotic Cells. Two Types Of Cells 1. PROKARYOTE 2. EUKARYOTE.

Cell Theory All living things are composed of cells.
Warm-up What is the difference between eukaryotic and prokaryotic cells? Which type of cells do humans have? So which type of cell is more complex?
A cell is the basic unit of life. The development and enhancement of microscopes made the observation and description of microscopic organisms and.
Cells: Prokaryotic vs. Eukaryotic. Cells Cells – basic unit of living organisms. Level of organization: < cell < tissue < organ < organ system < organism.
