Protozoans-Mastigophora

Front 1

What organelle is present on all Mastigophorians?

Back 1

-flagella

**Mastigophorians are sometimes called Flagellata**

**contains both plant-like and animal-like forms**

Front 2

List the organelles present in Euglena. (6 main ones.)

Back 2

-outer pellicle
-nucleus and nucleolus
-chloroplasts and cholorphyll
-paramylon bodies
-gullet
-flagella

Front 3

Is Euglena autotrophic or saprotrophic?

Back 3

-it is autotrophic but will become saprotrophic if kept in the dark, provided that peptones are added to the environment

Front 4

What are mastigonemes?

Back 4

-numerous lateral projections on flagella

Front 5

What is the flagella composed of?

Back 5

-9 peripheral microtubules and 2 central microtubules
-each peripheral microtubule is made of 2 microtubules

Front 6

What is the kinetosome composed of?

Back 6

-9 peripheral groups of microtubules
-each group consists of 3 microtubules

Front 7

How does Euglena recieve information of its environment?

Back 7

-has a red eyespot or stigma near the lateral margin of the cytopharynx

-positively phototrophic therefore move towards light
-stigma shades the light receptor so Euglena can focus in on the light source

**if stigma is destroyed, Euglena becomes negatively phototrophic**

Front 8

How does Euglena reproduce?

Back 8

-by asexual longitudinal division
-by encysting

Front 9

What order does Trypanosoma lewisi belong to?

Back 9

-belongs to the Order Kinetoplastida

Front 10

Where does Trypanosoma lewisi live?

Back 10

-lives in the blood of rats

Front 11

How is Trypanosoma lewisi transmitted?

Back 11

-transmitted from rat to rat from fleas

Front 12

What effect does trypanosomes have on man?

Back 12

-causes sleeping sickness in man
-may enter cerebro-spinal fluid and cause motor distubances, stupor and may even kill

Front 13

What order do choanoflagellates belong to?

Back 13

-the Order Choanoflagellida

Front 14

What are metamonads?

Back 14

-small orders of flagellate protozoans
-live symbiotically in the digestive or reproductive tracts of animals

Front 15

What is Opalina?

Back 15

-a parasite in the guts of frogs
-mulitnucleate and covered by thousands of cilia
-not considered ciliates because the division process follows the lines of cilia; division in ciliates cuts across the lines of cila
