INTRODUCTION
• All living things are made up of cells. Cells are the
smallest units that can be alive. During the 1950’s
scientists developed the concept that life on earth is
classified into six kingdoms and each have their own
characteristic kind of cell. However the biggest
division is between the cells of the Prokaryote
kingdom (Eubacteria and archaebacteria and those of
the other four kingdoms (animals, plants, fungi and
protoctista which are all eukaryotes cells.
Prokaryote is an organism that does not have a nucleus
(like bacteria), It still has DNA of course, but not
enclosed in a neat little sack.
Eukaryote is an organism that does have a nucleus (like
me and you)
Functions
• The Cell Wall• The Plasma Membrane• The Cytoplasm• The Genetic Material• The Ribosomes
Prokaryotic Cell• The Cell Wall• The Plasma Membrane• The Nucleus• The Nuclear Membrane• The Nucleolus• The Mitochondria• The Chloroplast• The Endoplasmic Reticulum• The Ribosomes• The Golgi Bodies• The Lysosomes• The Vacuoles• The Cytoplasm• The Chromosomes
Eukaryotic Cell
Below are the organelles of each cell. Each of these organelles have specific
functions.
DNA, the genetic material is located in a non-membrane
bound nucleoid region in prokaryotes and a membrane-
bound nucleus in eukaryotes
2. Plasma membrane, a phospholipid bilayer with
proteins that separates the cell from the surrounding
environment and functions as a selective barrier for the
import and export of materials
3. Cytoplasm, the rest of the material of the cell within
the plasma membrane, excluding the nucleoid region or
nucleus, that consists of a fluid portion called the
cytosol and the organelles and other particulates
suspended in it
4. Ribosomes, the organelles on which protein synthesis
takes place
Prokaryotic cells reproduce by a process that is called
binary fission.
The DNA in such cells is contained in a single circular
chromosome called a plasmid within the cytoplasm.
The reproductive process starts with the replication of
the chromosome.
Always asexual
Prokaryotic Cell Reproduction
The life of eukaryotic cells is characterized by a cell
cycle with two major phases: the interphase and cell
division.
The nucleus divides in a process called mitosis
Asexual or sexual
Eukaryotic Cell Reproduction
Application
• The Carbon Cycles affect possible survival.
• There are physical characteristics.
• The temperature varies.
• Environmental changes create problems.
Biotic and Abiotic Factors
Biotic Factors are;
• Producers (autroph) plants
• Consumers (hetertrophs) animals
• Decomposers (fungi and bacteria)
Abiotic Factors are;• Air
• Water
• Space
• Temperature
• Light
• Soil (nutrients
Feeding Systems
Feeding Systems that takes place in Prokaryotic
Organisms

Organisms within the Kingdoms
• Prokaryotes includes several kinds of microorganisms such as bacteria and cyanobacteria.
• Eukaryotes includes such microorganisms as fungi, protozoa and simple algue.
