Information/Questions
Ulothrix is a genus of
Kingdom: Protist
filamentous green algae,
Division: Chlorophyta
generally found in fresh
Class:
Ulvophyceae
and marine water. Its
cells are normally as
Order:
Ulotrichales
broad as they are long,
Family: Ulotrichaceae
and they thrive in the
Genus:
Ulothrix
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. They
Family: Zygnemataceae
can sexually
Genus:
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 plant-like
and animal-like?

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 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.
The Amoeba proteus is a large protozoan and
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?
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.
Saccharomyces cerevisiae is a species of budding
yeast. It is perhaps the most important yeast owing
to its use since ancient times in baking and brewing.
Make your own live slide from the flask of growing
yeast. Try to find evidence of budding.

Rhizopus
nigricans
Rhizopus nigricans is a type of black mold which is
known to grow on bread, therefore known as
breadmold. It is a known producer of allergens.
