Prokaryote, relatively simple unicellular
organism, such as a bacterium, characterized by the absence of a nucleus and
other specialized cell structures. Scientists distinguish prokaryotes from
eukaryotes, which are more complex organisms with cells that contain a nucleus,
such as plants and animals.
Examples
Virus, Bacteria, Cynobacteria (Blue Green Algae).
Kingdom
Protista
All
unicellular eukaryotic organisms included in this kingdom. They have distinct
nucleus and perform all living activities with in singular cell. These have
little complex cell structure then prokaryotes.
Examples
Amobea, Euglena, Paramacium etc
Kingdom
Fungi
Fungi, also eukaryotic and long considered members
of the plant kingdom, have now been placed in a separate kingdom because they
lack chlorophyll and plastids and because their rigid cell walls contain chitin
rather than cellulose. Unlike the majority of plants, fungi do not manufacture
their own food; instead they are saprophytic, absorbing their food from either
dead or living organic matter.
Example
Mashroom, Pancillium etc
Kingdom
Plantae
Plant cells have all the components of
animal cells and boast several added features, including chloroplasts, a
central vacuole, and a cell wall. Chloroplasts convert light energy—typically
from the Sun—into the sugar glucose, a form of chemical energy, in a process
known as photosynthesis. Chloroplasts, like mitochondria, possess a circular
chromosome and prokaryote-like ribosome, which manufacture the proteins that
the chloroplasts typically need.
Examples are All plants
Kingdom
animalae
Eukaryotic cells are typically about
ten times larger than prokaryotic cells. In animal cells, the plasma membrane,
rather than a cell wall, forms the cell’s outer boundary. With a design similar
to the plasma membrane of prokaryotic cells, it separates the cell from its
surroundings and regulates the traffic across the membrane.
