What is oxygen delivery?
I limit what enters and leaves the cell.
What is the cell membrane?
Groups of similar cells that work together to perform a specific function.
What is tissue?
This system breaks down food through mechanical and chemical digestion.
What is the digestive system?
All non-living organisms are made up of these.
What is an atom?
The muscular system interacts with this system to break down food.
What is the digestive system?
I produce most of the energy for the cell
What is the mitochondria?
Two or more tissues that work together to perform a specific function.
What is an organ?
This system brings air into the body and removes carbon dioxide.
What is the respiratory system?
A characteristic that provides evidence to classify something as a living thing is that it contains these.
What is a cell?
The nervous system sends signals from the brain to this system, telling it to contract so the skeleton can move.
What is the muscular system?
In plant cells, I provide structure and support. I'm rigid and give the cell a definite shape.
What is the cell wall?
Different organs working together to perform major body functions.
What is an organ system?
This system removes liquid wastes from the body
What is the excretory system?
This is an example of a unicellular organism that moves by forming pseudopodia.
What is an amoeba?

What is shiver (or contract)?
In plant cells, I perform photosynthesis to make food for the cell.
What is the chloroplast?
An organism made up of only ONE cell that performs all life functions by itself.
What is a unicellular organism?
This system provides support and structure to the body and works with muscles to create movement.
What is the skeletal system?
The correct sequence of how the body responds to touching a hot stove: receptor detects → _____ → _____ → _____.
What is nerve sends signal → brain processes → muscle responds?
Three body systems that would best coordinate a movement like throwing a ball.
What is the nervous, muscular, and skeletal systems?
