Title, labels on axes, numbers on gridlines, units, data points
200
Name the three microorganisms that you saw.
Paramecium, Amoeba, Euglena
200
What is a flagella?
It is a whiplike tail found in single-celled organisms to aid in movement.
200
All organisms can survive as single cells. True or False?
False
200
What does the cell membrane do?
It holds everything in and lets some things in.
300
Why are graphs important?
They help people represent numerical data in picture form.
300
Where do all of these microorganisms live?
Water - all life is aquatic!
300
What are cilia?
Little hairlike projections that aid in locomotion and move materials outside of the cell membrane in some protists.
300
Only multicellular organisms are capable of reproduction. True or false?
False - both single-celled and multicellular organisms display all characteristics of life
300
Which two organisms that we viewed contained chloroplasts?
Elodea and euglena
400
If you are given a table with a name of an organism and the length of one cell, what is the independent variable and what is the dependent variable?
Independent - name of organism
Dependent - length of one cell
400
What kingdom at the microorganisms in?
Kingdom Protista - they are protists
400
What does a water-expelling vesicle do?
It collects and removes excess water from a single-celled organism.
400
How are single-celled organisms different from multicellular organisms?
Single-celled organisms live on their own and display all characteristics of life. Multicellular organisms have many cells that work together to display characteristics of life. One by itself would die.
500
How does an independent variable differ from a dependent variable?
An independent variable can be manipulated and chosen by the scientist. The dependent variable depends on or responds to the independent variable. (For example, you can change the surface of an experiment and the frictional force will depend on the surface texture.)
500
Single-celled organisms make up what percentage of the biomass of Earth?
50% (can you believe it??)
500
What is a chloroplast?
A chloroplast is an organelle that converts light energy into chemical energy (sugar).
500
Why can't an Elodea cell survive on its own?
Elodea is a multicellular organism and needs many cells working together to survive. One Elodea cell alone will die without the help of the other cells working together.
500
Name seven characteristics of life
Grows, Reproduces, Needs water, Needs food, Responds to stimuli, Eliminates Waste, Exchanges gas, made of cells!
