What is the basic unit of structure and function in living things?
This body system transports oxygen and nutrients through the body.
What is the circulatory system?
This tool helps scientists view cells that are too small to see with the naked eye.
What is a microscope?
This structure controls what enters and leaves the cell.
What is the cell membrane?
Cells combine to form this level of organization.
What is tissue?
This tiny structure controls the activities of the cell
What is the nucleus?
This body system helps the body take in oxygen and remove carbon dioxide.
What is the respiratory system?
Scientists use these to represent things that are too small, large, or complex to study directly.
What are models?
Plant cells have this structure that provides support and protection.
What is the cell wall?
Tissues combine to form this level of organization.
What is an organ?
The jelly-like material inside the cell where organelles are found.
What is cytoplasm?
This body system breaks down food into nutrients the body can use.
What is the digestive system?
The part of the microscope you look through.
What is the eyepiece?
This process allows cells to get energy from food.
What is cellular respiration?
Organs working together form this level of organization.
What is an organ system?
This organelle is known as the “powerhouse of the cell.”
What is the mitochondria?
This body system sends messages throughout the body.
What is the nervous system?
This microscope part holds the slide in place.
What are stage clips?
This organelle in plant cells captures sunlight to make food.
What are chloroplasts?
This term describes how parts of a system depend on each other.
What is interdependence?
A group of similar cells working together to perform a specific function.
What is tissue?
These two body systems work closely together to deliver oxygen to cells.
What are the respiratory and circulatory systems?
Why do scientists use models when studying cells and systems?
What is to explain, visualize, or predict how systems work?
Explain why cells are considered a system.
What is because the organelles work together to keep the cell functioning?
If one body system stops working properly, this can happen to other systems.
What is other systems may also be affected because systems depend on one another?
