What is the basic unit of structure and function in all living things?
Cell
Which organelle controls the activities of the cell?
Nucleus
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!
What might happen if a cell's nucleus could no longer control the cell?
The cell would have difficulty controlling its activities.
You look at a cell and see a dark circular structure towards the middle. What organelle might it be?
Nucleus!
What is the difference between a unicellular organism and a multicellular organism?
Unicellular has ONE cell.
Multicellular has MANY cells.
Which organelle controls what enters and leaves the cell?
Cell Membrane
Which type of cell has chloroplasts? What is it used for?
Plant cell and it's used to make food.
What might happen if the cell membrane stopped controlling what enters and leaves?
Materials could enter or leave the cell when they shouldn't.
You observe something with your eyes. Is that an observation or an inference?
Observation
True or false: All living things are made of one or more cells.
True
Which organelle releases energy the cell can use?
Mitochondria
What is the difference of the VACUOLES in both animal and plant cells?
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.
A student writes, “The cell is healthy.” Is that an observation or an inference?
Inference
Is this organism unicellular or multicellular? How do you know?
Multicellular because we can see the organism!
Which organelle makes proteins?
Ribosomes
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.
A plant cell cannot use its chloroplasts. What cell process would be affected?
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!
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.
Which organelle modifies, sorts, and packages materials for the cell?
Golgi Apparatus
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.
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.
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.
