Kingdom Bacteria
Bacteria are simple prokaryotic single celled
organisms that are found either as
individuals, in colonies (groups of cells
together) or in chains (cells attached end
to end).
Generally they are any where from 1 - 5
micrometers in size.
They are classified according to the shape
of the individual cell
Reproduction
• Bacterial cells reproduce by means of
asexual reproduction also known as
binary fission.
• In this process one cell divides into two
daughter cells that have the identical
genetic material.
Bacteria can not reproduce by mitosis or
meiosis because they do not contain a
nucleus. The genetic material is contained
within a single chromosome strand.
As the cell develops it makes a copy
of its original chromosome.
When the cell reaches a certain size it
elongates and the copied chromosome
moves to the opposite side of the cell. A
partition builds between the two strands
Eventually the original cell splits
into two new daughter cells.

HOW PLANTS AND ANIMALS DIFFER
Plants and animals are both kingdoms of living things. They differ in
important aspects. The chart below summarizes some of these differences.
PLANTS
ANIMALSPlants generally are rooted in one place an do not move on their
ownMost animals have the ability to move fairly freely.Plants contain
chlorophyl and can make their own food
Animals cannot make their own food and are dependent on plants and other
animals for food.
Plants give off oxygen and take in carbon dioxide given off by animals.
Animals give off carbon dioxide which plants need to make food and take in
oxygen which they need to breathe.Plants cells have cell walls and other
structures differ from those of animals. Animal cells do not have cell walls
and have different structures than plant cellsPlants have either no or very
basic ability to sense.Animals have a much more highly develped sensory
and nervous system.
