Mastigophora
-
(Flagellates) -
They
possess
one
or
more
whiplike,
undulating
flagella
to
propel
the
cell
forward.
The
structure
of
flagellum
is
similar
to
that
of
a
sperm
cell
flagellum,
with
typical
9+2
arrangement.
Undulations
sweep
down
the
flagella
to
the
tip,
and
the
lashing
motion
forces
water
outward
to
provide
locomotion.
This
class
includes
the
largest
(about
50%)
collection
of
protozoa.
Acommon
example
is
the
green
flagellate,Euglena
gracilis,
It
has
a
single
nulceus
and
flagellum,
and
an
elongated
cell
structure.
It
occurs
in
fresh
water
ponds.
It
Contains
chloroplasts
in
the
cytoplasm,
thus
photosynthetic.
Another
example
of
similar
type
is
Astasia
longa
.
This
group
also
includes
some
important
human
parasites
infecting
nervous,
urogenital
and
intestinal
systems.
