Unicellular organisms that lack organelles or other internal membrane-bound structures.
Prokaryotes lack an
organized nucleus and
other membrane-bound
organelles.
Prokaryotic cell size ranges from
0.1 to 5.0 μm in diameter.
The cell wall of a prokaryote acts as an extra layer
of protection, helps maintain cell shape, and
prevents dehydration.
Prokaryotic DNA is found in
a central part of the cell
called the nucleoid.
The small size of prokaryotes
allows quick entry and diffusion of
ions and molecules to other parts
of the cell while also allowing fast
removal of waste products out of
the cell.
Prokaryotes have a prokaryotic cytoskeleton
Bacteria are an example of prokaryotic cells
Eukaryotic
Fungi
a kind of living organism: yeasts,
moulds and mushrooms are types of
fungi. The fungi are a separate
kingdom of living things, different
from animals and plants. Fungi have
cells with nuclei. Their cell walls contain
chitin, unlike the cell walls of plants,
which contain cellulose.
The most common form
of fungi are mushrooms,
molds and yeasts
Mushrooms
Experts believe the
only 3/5 of what is
assumed to be all
the species of
mushrooms has
been discovered.
That's a staggering
60%!
Moulds
Yeasts
Around 120,000 species of fungi have been
described by taxonomists
Animals
A living organism that feeds
on organic matter, typically
having specialized sense
organs and nervous system
and able to respond rapidly
to stimuli.
Invertebrates, fish,
amphibians,
reptiles, birds and
mammals are the
6 main animal
groups.
microorganisms that are
similar to bacteria in size
and simplicity of structure
but radically different in
molecular organization.
They are now believed to
constitute an ancient
intermediate group
between the bacteria and
eukaryotes.
Methanogens, halophiles, and
thermophiles are the main
types of archaebacteria.
Methanogens
Produce methane
Halophiles
Salt-loving
Thermophiles
Thrive in high temperatures
Plants
a living organism of the
kind exemplified by
trees, shrubs, herbs,
grasses, ferns, and
mosses, typically
growing in a permanent
site, absorbing water
and inorganic substances
through its roots, and
synthesizing nutrients in
its leaves by
photosynthesis using the
green pigment
chlorophyll.
mosses and liverworts,
ferns, gymnosperms, and
angiosperms are the
four groups of the plant
kingdom
