Biology: Animal-like Protista

flagellum

a long, whip-like tail or part, used by certain protozoa for locomotion.

binary fission

a method of asexual reproduction in animals in which a one-celled organism divides by mitosis into two organisms.

cyst

a protective capsule occupied by protozoa during unfavorable condition of the environment.

cytoplasmic bridge

a temporary thin strand of cytoplasm connecting two microorganisms during conjugation through which structure genetic material may be passed between cells.

pellicle

a thin and firm, but elastic layer over the cell membrane that gives shape to some microorganisms.

contractile vacuole

a vacuole in unicellular organisms that collects water and wastes and expels them in order to maintain the organism's proper water content.

food vacuole

a vacuole in which food particles are digested by enzymes.

Motile

able to move by itself

cytoplasm

all the material inside a cell membrane except the nucleus.

taxis

an organism's response to a stimulus

chemotaxis

an organism's response to the presence of chemical in its surroundings.

phototaxis

an organism's response to the variability of light in its surroundings.

longitudinal binary fission

asexual reproduction in which the parent organisms divided lengthwise to for two daughter cells which are mirror-images of each other.

radiolarian

the common name for amoeboid protozoans of the phylum Foraminifera which is characterized by tiny shell like structures composed of silicon.

gullet

the deepest part of the oral groove where food vacuoles are formed around a food particle

Protozoa

the phylum comprising unicellular organisms in the protista kingdom.

Phizopoda

the phylum of amoeboid protozoans

Actinipoda

the phylum of amoeboid protozoans which have tiny shell-like structure composed of calcium carbonate.

Apicomplexa

the phylum of parasitic spore forming protozoans which are not motile during most of there life.

ciliphora

the phylum of protozoans with cilia, the species of which phylum are commonly known as ciliates.

Zoomastigophora

the phylum of protozoans, commonly known as flagellates with flagella.

phagocytosis

the process of enclosing food particles by the cell membrane to form an internal food vacuole.

homeostasis

the self regulating exchange of water, dissolved materials and dissolved gases between a cell and its surroundings.

Anal Pore (Paramecium)

the structure of a paramecium where undigested food is eliminated from the cell

the Plasmodium life cycle,

the asexual portion is clinical symptoms of malaria. The sexual portion releases the spores into the human blood stream.

Forminifera

the phylum of amoeboid protozoans commonly called radiolarians, which have a tiny shell like structure composed of silicon.

Trypanosoma cruzi

triatomine bug

All species of the phylum Apicomplexa are parasitic.

true

Giardia lamblia

water-borne cysts

How many nucleus does paramecium have

2

What is the final result of protozoan conjugation?

Four new protozoans are created.

apical complex

a cell structure found only in parasitic species of the phylum Apicomplexa; important for interaction with and entry into host cells

conjugation

a kind of reproduction in which two unicellular organisms unites temporarily to exchange nuclear material, then separate.

pseudopodium

false feet (the streaming protoplasm of the amoeba)

you might find zooflagellates living in

fresh water lakes, inside other organisms

cilia

hair-like bits of protoplasm that project from certain kinds of cells for locomotion or feeding.

amoeboid

movement by altering the consistency of cytoplasm so that it flows to create pseudopia.

Trypanosoma

African sleeping sickness, tsetse fly

eukaryotic cells

Contain a nucleus and other organelles that are bound by membranes.

Entamoeba histolytica

is an amoebic protozoan which is responsible for a disease known as amoebic dysentery. Cysts formed by Entamoeba histolytica can live outside the human body and may contaminate water or be carried by houseflies. Symptoms include severe diarrhea which can lead to death if not treated.

The Anopheles mosquito is the insect vector for _________.

malaria

Leishmania donovani

phlebotimine sand fly

Termites and Trichonympha have a

symbiotic relationship.
