What are the ways within which microbiologists classify protists?
a)
Microbiologists classify protists by the way they look. Some of them are green in color, while others are clear.
b)
Microbiologist classify protists by observing their method of obtaining energy.
c)
Microbiologists classify protists by observing how they move. Some protists use cilia to move, while some other use cytoplasmic streaming or flagellum.
d)
Microbiologists classify protists by observing how they move, and the protists method of obtaining energy.
2.
As we already know, heterotrophic protists are animal-like in extracting energy for food. What does it mean when a protist is "heterotrophic"?
a)
Heterotrophic protists are protists that have to move to find their food, and eat smaller organisms to survive. Sometimes, these types of protists eat each other, or other protists.
b)
Heterotrophic protists are protists that do not have to move to fin their own food, rather, these protists can perform photosynthesis which allows for these types of protists to create their own food.
c)
Heterotrophic protists can find their own food, and create their own food.
d)
Heterotrophic protists feed off of decaying matter which can include dead trees.
3.
As we already know, autotrophic protists are plant-like in extracting food for energy. What does it mean when a protist is "autotrophic"?
a)
Autotrophic protists are protists that have to move to find their food, and eat smaller organisms to survive. Sometimes, these types of protists eat each other, or other protists.
b)
Autotrophic protists are protists that do not have to move to fin their own food, rather, these protists can perform photosynthesis which allows for these types of protists to create their own food.
c)
Autotrophic protists feed off of decaying matter which can include dead trees
d)
Autotrophic protists are protists that can move to find their own food, and eat smaller organisms to survive, can produce photosynthesis to create their own food, and feed off of decaying matter which can include dead trees.
4.
The animal-like protist, called the paramecium, lives in water. The paramecium can move in the water by using tiny hairlike structures called?
a)
Parameciums use a tiny hairlike structure called a flagella to move throughout its watery environment.
b)
Parameciums use a tiny hairlike structure called pseudopods to move throughout its watery environment.
c)
Parameciums use a tiny hairlike structure called cilia to move throughout its watery environment.
d)
Parameciums use a tiny hairlike structure called a pellicle to move throughout its watery environment.
5.
One of the animal-like protist, called the amoeba, lives in ponds, rivers, streams, and lakes. How does the amoeba move throughout its watery environment?
a)
The amoeba moves by cilia, which is a hair-like structure that allows it to move and force food into its gullet.
b)
The amoeba moves by a flagellum, which is a whip-like structure that allows it to move throughout its watery environment.
c)
The amoeba moves by cytoplasmic streaming using pseudopods, which allows the amoeba to move throughout its watery environment, and consume other tiny organisms.
d)
The amoeba moves by a pellicle, which is a thin layer supporting the cell membrane in various protists that allows for the protist to expand and contract its body.
6.
As we already know, protists are eukaryotic meaning
a)
Eukaryotic organisms are organisms that lack a nucleus organelle. This means tat the DNA inside the cell is free floating.
b)
Eukaryotic organisms are organisms that have a nucleus organelle. This means that the DNA inside the cell is inside the nucleus.
7.
The euglena and volvox are part of the plant-like protists. Which of the following organelles is responsible for identifying this protists to be plant-like in nature?
a)
Cilia - Each volvox and euglena have cilia which are tiny hair-like structures that allow the euglena and volvox to move around its watery environment.
b)
chloroplasts - Each volvox and euglena contain the organelle chloroplast within which the chloroplast allows the plant-like protists to perform photosynthesis.
c)
Cell Membrane - Each volvox and euglena contain a cell membrane, within which the cell membrane allows the movement of organelles across its cell.
d)
Cilia & Chloroplasts are both found in the euglena and volvox which is responsible for identifying these protists to be plant-like in nature.
8.
How does the euglena know how to detect light during the daytime?
a)
The euglena can sense light with its flagellum, which allows the euglena to move towards the light.
b)
The euglena can sense light with its eyespot (stigma), which allows the euglena to sense light.
c)
The euglena can sense light with its chloroplasts, within which the chloroplast allows the cell to create its own food through photosynthesis
d)
The euglena uses its pellicle to squiggle and squirm its way towards the sunlight, within which the pellicle can detect sunlight, and allow the cell to move towards the sunlight.
