Scientific Inquiry
Anglica notices muscle cells and brain cells have a different shape. This is a/an...
observation
All living things are made of...
cells
Humans are made of more than one kind of cell. True or False?
True
A word used to describe how much of something there is within a certain amount of space is...
concentration
In order for the different parts of the body to communicate with each other, the cells in those parts of the body have to communicate with each other. True/False
True
Angelica thinks muscle cells and brain cells may have different shapes because it helps them be good at different things. This is a/an...
inference
A cell needs to make the protein insulin. The blueprints/directions needed to make it is called...
DNA
This part of the cell keeps the DNA safe, and controls what happens in the cell.
Nucleus
High concentration to low concentration
One cell can send a message to another cell by sending out a/an ....
messenger protein or hormone
Angelica decides the best WAY to tell whether brain tissue or muscle tissue is tougher is to pull on it and see how much strength it takes to tear it. She came up with a ________ for testing it.
method/procedure
Bacteria are made out of only 1 cell. Humans are made out of trillions of cells. This means we would say bacteria are _____________ and humans are _____________.
Bacteria are unicellular, humans are multicellular.
Order these from BIGGEST to SMALLEST:
Cell, mitochondria, protein.
Cell, mitochondria, protein.
When something spreads out on its own and doesn't need help to do it, it is called...
simple diffusion
A cell needs to have a ________ in order to receive a message.
receptor protein
Angelica found that muscle tissue took more strength to tear than brain tissue did. Jose and Evidalia decided to see if they got the same results when they did the experiment. Jose pulled on the muscle tissue, and Evidalia pulled on the brain tissue. Jose and Evidalia found that the muscle tissue tore EASIER. What might explain Angelica getting different results from Jose and Evidalia?
Jose and Evidalia might not be the same strength.
This organelle is needed to break things down inside an animal cell (much like a stomach breaks things down).
Lysosome
The DNA needed to make insulin is good. However, the insulin our pancreas cells are making is not coming out in the shape it is supposed to. What organelle in the pancreas cells is probably messed up?
Ribosome
Passive transport includes both ______________ and ____________.
Simple diffusion and facilitated diffusion.
AFTERNOON CLASS ONLY: Insulin is sent from an organ called the pancreas. If it doesn't make it to the cells, what will be the consequence?
Sugar will not make it into the cell.
-any three things she makes sure to keep the same when she tests out the muscle tissue and when she tests out the brain tissue.
A spider bite has venom that causes cells to not be able to control what comes in our out of the cell. The spider venom probably damaged the part of the cell called the _________________.
cell membrane
Which of these are organelles and which are not?
Nucleus, cell, organism, transport protein, chloroplast, tissue.
Organelles: nucleus, chloroplast
Not organelles: cell, organism, transport protein, tissue
transport protein, mitochondria (can't make ATP needed for active transport), ribosome needed to make transport protein, or the DNA needed for any of these three things.
Many possible answers.
