Protist

Name one advantage each of observing the live culture and the prepared slide.

A live culture allows you to see movement and watch the different organisms interact. A prepared slide allows the observer to see things that are very rare and that cannot be transported. By using a prepared slide you can look at certain specimens that were obtained 30-40 years ago.

Blood testing by a serological test system which identifies those that are repeatedly reactive for antibodies to Tyrypanosoma. The presence of antibodies to Trypanosoma identifies the infected.

Encysted

e. Name one parasite amoeba that is found in the human mouth.

Entamoeba, Gingivalis

Describe the pattern on movement in Euglena:

Euglena has two types of flagellum that aids in movement. One is whiplash flagellum which pushes the organism through the medium and the other is tinsel flagellum which pulls the organism through the environment.

Who am I? I am a vector for malaria.

Female Anopheles mosquito

What species is the definitive host of Plasmodium?

Female anopheles mosquitos

Where (species and locations in what species) does fertilization occur in Plasmodium?

Fertilization occurs in the mosquito's stomach, producing zygotes (sporozoa).

What is the function of cilia in Vorticella?

Forms a water current to bring food toward its mouth. This aids in capturing food.

Is Paramecium AUTOTROPHIC HETEROTROPHIC or BOTH?

HETEROTROPHIC

Is Trypanosoma AUTOTROPHIC or HETEROTROPHIC or BOTH?

HETEROTROPHIC

Is the amoeba AUTOTROPHIC or HETEROTROPHIC or BOTH?

Heterotrophic

Which species are the intermediate host of Plasmodium?

Human and other mammals

Describe the response of Vorticella of being disturbed

If disturbed, the response would be the stalks coiling up.

What ecological problem do dinoflagellates occasionally cause?

If they grow out of control, they can reach high levels of concentrations and discolor water. The toxins and anoxic conditions produced by red tides often poison marine life.

Describe the pattern of movement as the Vorticella feeds

It feeds on bacteria by creating a vortex with its cilia to direct food towards the mouth.

Describe the pattern of movement as the organism feeds

It feeds on bacteria by creating a vortex with its cilia to direct food towards the mouth.

Euglena belongs to what Kingdom and what subkingdom?

Kingdom Protista Subkingdom Protozoa

What are RED TIDES?

Large population "blooms" by Dinoflagellates that color the ocean waters a deep reddish hue for miles

Organelle of Ciliates responsible for metabolic processes?

MACRONUCLEUS

Paramecium moves using A SINGLE FLAGELLUM or MANY FLAGELLA or MANY CILIA

MANY CILIA

Which life stage(s) give rise to gametes in Plasmodium? MEROZOITE and/or SPOROZOITE and/or TROPHOZOITE

MEROZOITE and TROPHOZOITE

Organelle of Ciliates responsible for SEXUAL REPRODUCTION?

MICRONUCLEUS

Name two ways that Euglena is animal-like

Method of food storage, storing glucose in the form of lipids rather than starch Can move from one place to another, locomotion.

Name the human organ and human cells infected by Plasmodium:

ORGAN- LIVER CELLS- RBCs

Which of the following does the contractile vacuole functions in amoebozoa? FEEDING or REPRODUCTION or OSMOREGULATION

OSMOREGULATION

NAME OF STRUCTURE USED BY AMOEBA FOR FEEDING:

PSEUDOPODS

How does Paramecium feed?

Paramecium use its cilia to sweep prey organisms, along with some water, through the oral groove, and into the mouth opening.

Compared to Euglena, how do Peridinium move?

Peridinium move with two flagella, which help control movement through water. The dinoflagellates push themselves through the water with their flagella. Although euglenoid movement is primarily accomplished by flagella, its flexible pellicle rapidly extends and contracts by sliding microtubules and protein stripes to aid in locomotion.

Is PHAGOCYTOSIS or PINOCYTOSIS the process in which a unicellular animal engulfs food particles within its cell walls?

Phagocytosis

Is PHAGOCYTOSIS or PINOCYTOSIS the process in which a unicellular animal takes up liquids by creating invagination in its cell walls?

Pinocytosis

The eyespot functions for a Euglena in REPRODUCTION or FEEDING or SENSING LIGHT

SENSING LIGHT

Euglena moves using A SINGLE FLAGELLUM or TWO FLAGELLA or MANY CILIA

SINGLE FLAGELLUM

In which life stage(s) does asexual reproduction occur in Plasmodium? MEROZOITE and/or SPOROZOITE and/or TROPHOZOITE

SPOROZOITE

Name of Plasmodium cells released into the salivary gland?

SPOROZOITES

How many hosts does Plasmodium require? NONE ONE TWO THREE UNDETERMINED

TWO

Peridinium move using A SINGLE FLAGELLUM or TWO FLAGELLA or MANY CILIA

TWO FLAGELLA

Why might the term spiral movement be used to describe the pattern of locomotion in Paramecium?

The cilia causes the movement and helps find food on the way.

What is the ecological importance of dinoflagellates?

The ecological importance of dinoflagellates is that they provide 90% of coral energy and are primary producers of food in the aquatic food chain.

Give the characteristics of Euglena, why might the eyespot be present?

The eyespot serves as a photoreceptor, providing chemical information to the cell about the intensity of light in its environment.

Name two locations where asexual reproduction might occur in Plasmodium. Be sure to include the organism.

The liver (entering the bloodstream) (human) Red blood cells (digest the globin and RBC's ruture) (human)
