The purpose of photosynthesis is to produce this energy-rich molecule. 

What is glucose?

100

This organelle produces ATP energy. 

What is the mitochondrion?

100

These types of cells include animals, plants, fungi, and protists. 

What are eukaryotes?

100

This organ is the center of the circulatory system. 

What is the heart?

100

The top of the food chain. 

What is an apex predator?

200

This molecule is our most directly usable form of energy. 

What is ATP?

200

This organelle produces proteins from mRNA. 

What are the ribosomes?
200

These types of cells include bacteria. 

What are prokaryotes?

200

This organ releases digestive enzymes into the stomach. 

What is the liver?

200

An organism may be considered this if it moves to a new environment where it has no natural predators. 

What is invasive?

300

These biomolecules are always hydrophobic. 

What are lipids?

300

This organelle stores DNA. 

What is the nucleus?

300

These types of cells have cell walls for stability and lysosomes for digestion. 

What are fungi?

300

This organ produces eggs.

What are the ovaries?

300

Organisms that must consume other organisms for energy.

What are heterotrophs?

400

These proteins speed up chemical reactions, typically either breaking down a substrate or combining multiple substrates. 

What are enzymes?

400

This organelle stores water. It is larger in plant cells and smaller in animal cells.

What is the vacuole?

400

These types of cells have a cell wall, chloroplasts, and nuclei, and they always form multicellular organisms. 

What are plant cells?

400

This organ filters the blood and produces urine.

What are the kidneys?

400

In the carbon cycle, these organisms are responsible for removing carbon dioxide from the atmosphere.

What are plants?

500

When a protein or nucleic acid loses its shape. 

What is being denatured?
500

This organelle transports materials around the cell. 

What is the golgi body?

500

These types of eukaryotic cells may be single-celled or multi-cellular, and may resemble plants or animals, but are always simpler in structure. 

What are protists?

500

This organ helps to feed a developing embryo. 

What is the placenta?

500
When an organism dies, the energy contained within it travels to these organisms. 

What are decomposers?
