Cell Functions
List 3 ieas of the cell theory
All living things are made of cells; all cells come from preexisting cells; cells perform the functions of living things.
Who first saw and named cells, and when?
Robert Hooke, in the 1600s.
An organelle is...
A structure inside a cell that does a special job.
What is the difference between eukaryotic and prokaryotic cells?
Eukaryotic cells have a nucleus; prokaryotic cells do not.
What is the first step of the scientific method?
Asking a question
What is ATP?
The cells energy currency
Why is the cell theory called a model?
It usefully explains our observations but is not absolute truth and can be changed.
The cell membrane does this
It surrounds the cell and controls what enters and exits (it is selectively permeable).
What is a tissue?
A tissue is a group of similar cells working together
Identify the Independent Variable:
Different types of liquid were given to athletes and their running speed was measured.
Type of liquid
The difference between a producer and a consumer is that a producer
A producer makes its own food; a consumer eats other organisms.
What is the major difference between creationists and evolutionists view of the cell?
Creationists believe that God created it in one day and evolutionists believe it changed and formed over time.
What is the “powerhouse of the cell”?
Mitochondria
What is an organ?
A group of tissues working together
Identify the Dependent variable:
Students were allowed 1, 3 and 5 hours on screens in a given day and the number of hours they slept was recorded.
Number of hours the students slept
What is photosynthesis and what does it produce?
It uses sunlight to turn carbon dioxide and water into glucose (sugar) and oxygen.
On what day did God create land animals and Adam & Eve?
Day 6
Mitochondria makes this energy
ATP
Put in order from smallest to largest: organ, cell, tissue
Cell, tissue, organ.
What is the final step of the scientific method?
Presenting findings
What do chloroplasts do
Converts light energy into
chemical energy through the
process of photosynethesis.
How the plant cells looked in a microscope (like rooms/cells)
What is the difference between passive and active transport
Passive transport needs no energy; active transport uses energy
An example of a eukaryotic cell is...
Animal cells, plant cells, fungal cells, and protists are all examples of eukaryotic cells.
Identify the Independent variable:
Students were given exams on paper or a computer and the length of time it took them to complete the test was recorded.
The exam format
