Information/Questions
Ulothrix is a genus of
Kingdom: Protist
filamentous green
Division: Chlorophyta
algae, generally found
Class:
Ulvophyceae
in fresh and marine
water. Its cells are
Order:
Ulotrichales
normally as broad as
Family: Ulotrichaceae
they are long, and they
Genus:
Ulothrix
thrive in the low
temperatures of spring
and winter. They
become attached to surfaces by a modified holdfast
cell. Reproduction is normally vegetative.
Diatoms are a major group of eukaryotic algae,
and are one of the most common types of
phytoplankton. Most diatoms are unicellular,
although some form chains or simple colonies. A
characteristic feature of diatom cells is that they
are encased within a unique cell wall made of
silica. These walls show a wide diversity in form,
some quite beautiful and ornate, but usually consist
of two asymmetrical sides with a split between
them, hence the group name.
Spirogyra is a genus Kingdom: Protista
of filamentous green
Division: Charophyta
alga of the order
Phylum: Chlorophyta
Zygnematales. It is
commonly found in
Order:
Zygnematales
freshwater areas.
Family: Zygnemataceae
They can sexually

Spirogyra
reproduce by
conjugation.
Volvox is the most developed in a series of genera
that form spherical colonies. Each Volvox is
composed of numerous flagellate cells on the order
of 1000-3000 in total, interconnected and arranged
in a hollow sphere. The cells swim in coordinated
fashion, with a distinct anterior and The cells have
eyespots, more developed near the anterior, which
enables the colony to swim towards light.
The name comes from the Greek words εὔ (eu) and
γλήνη (glēnē), meaning good eyeball, referring to
their light-sensitive eyespots used to direct
themselves towards light. Over 1000 species of
Euglena have been described.
Why could Euglena be considered both plantlike and animal-like?
Chlamydomonas is a genus of green alga.
What type of structure do they use to move?

Anabaena is a genus of filamentous cyanobacteria,
or blue-green algae, found as plankton. It is known
for its nitrogen fixing abilities, and they form
symbiotic relationships with certain plants, such as
the mosquito fern. They are one of four genera of
cyanobacteria that produce neurotoxins, which are
harmful to local wildlife, as well as farm animals
and pets.
Trypanosoma Trypanosoma brucei is a notable parasitic species
of Trypanosoma. The species causes African
trypanosomiasis (or sleeping sickness) in humans
and animals in Africa. The entirely parasitic
species has two hosts - its insect vector and
mammalian host. Because of the large difference
between these hosts the cell undergoes complex
changes to facilitate its survival in the insect gut
and the mammalian bloodstream. It also features a
unique and notable variable surface glycoprotein
(VSG) coat in order to avoid the host's immune
system.
Amoeba
The Amoeba proteus is a large protozoan and
proteus
belongs to the Phyllum Sarcodina. It has an ever
changing shape . It can almost be seen with the
naked eye. What structure does the amoeba use
to move?
Anabaena
Paramecium
caudatum
Paramecium caudatum cannot survive without the
macronucleus and cannot reproduce without the
micronucleus. Reproduction is either by asexual
binary fission or occasionally by conjugation
(sexual). During binary fission a fully-grown
organism divides into two daughter cells.
Conjugation consists of the temporary union of 2
organisms and the exchange of micronuclear
elements. Without the rejuvenating effects of
conjugation a paramecium ages and dies.
