An organic compound contains this element.
What is carbon?
100
The movement of materials from an area of high concentration to an area of low concentration.
What is diffusion?
100
The "powerhouse" of the cell because it converts energy in food molecules to energy the cell can use to carry out its functions.
What is the mitochondria?

What is the microscope?
300
This part of the cell is a rigid layer of nonliving material that supports and protects the cells in plants and some other organisms.
What is the cell wall?
300
Two or more elements chemically combined.
What is a compound?
300
Movement of molecules across a cellular membrane that requires the use of cellular energy.
What is active transport?
300
These green organelles are found in plant cells an some other organisms. They capture energy from sunlight and use it to produce food for the cell.
