100
What is the basic unit of structure and function in all living things?
Cell
100
Which organelle controls the activities of the cell?
Nucleus
100
Which type of cell has a cell wall: plant, animal, or both?
How does it impact the SHAPE of the cell?
Plant Cell. It makes the cells look more square!
100
What might happen if a cell's nucleus could no longer control the cell?
The cell would have difficulty controlling its activities.
100
You look at a cell and see a dark circular structure towards the middle. What organelle might it be?
Nucleus!
200
What is the difference between a unicellular organism and a multicellular organism?
Unicellular has ONE cell.
Multicellular has MANY cells.
200
Which organelle controls what enters and leaves the cell?
Cell Membrane
200
Which type of cell has chloroplasts? What is it used for?
Plant cell and it's used to make food.
200
What might happen if the cell membrane stopped controlling what enters and leaves?
Materials could enter or leave the cell when they shouldn't.
200
You observe something with your eyes. Is that an observation or an inference?
Observation
300
True or false: All living things are made of one or more cells.
True
300
Which organelle releases energy the cell can use?
Mitochondria
300
What is the difference of the VACUOLES in both animal and plant cells?
Plant cells have one large central vacuole and animal cell have many small vacuoles.
300
A cell needs to move materials from one part of the cell to another. The materials are packaged inside a small structure. What structure is helping move these materials, and what is its job?
A vesicle. Vesicles transport materials from one part of the cell to another.
300
A student writes, “The cell is healthy.” Is that an observation or an inference?
Inference
400
Is this organism unicellular or multicellular? How do you know?
Multicellular because we can see the organism!
400
Which organelle makes proteins?
Ribosomes
400
Name two structures that plant and animal cells both have.
They both have: nucleus, cell membrane, cytoplasm, mitochondria, ribosomes, ER, Golgi, etc.
They both make up living things.
400
A plant cell cannot use its chloroplasts. What cell process would be affected?
It would affect photosynthesis or the plants ability to make its own food!
400
A student writes, “I see several small structures inside the cell.” Is that an observation or inference?
Observation because they are describing what they see!
500
What are the three main ideas of cell theory?
Living things are made of cells
Cells are the basic unit of life
Cells come from existing cells.
500
Which organelle modifies, sorts, and packages materials for the cell?
Golgi Apparatus
500
A scientist observes a cell with a cell membrane, nucleus, chloroplasts, and a cell wall.
Scientist #1 says: “This is a plant cell.”
Scientist #2 says: “This is an animal cell.”
Who is correct? Use TWO pieces of evidence from the cell to support your answer.
The first scientist is correct: it is a plant cell. The chloroplasts and cell wall are evidence that it is a plant cell.
500
A cell makes a protein, but the protein needs to be modified and packaged before it can be transported to another location in the cell. Which TWO organelles would work together to complete these jobs? Explain what each organelle does.
Rough ER helps make/process the protein, and the Golgi apparatus modifies, sorts, and packages it.
500
Why should scientists record observations before making conclusions about what they see?
So they can use evidence from what they actually observed to support their conclusions.
