This part of the cell controls what goes in and out.

What is the cell membrane

100

This sugar molecule is the main source of energy for cells.

πŸ‘‰ What is glucose?


100

These tiny particles are the basic building blocks of all matter.

What are atoms?

100

This word describes a characteristic that can be passed from parent to offspring.

What is a trait?

100

This gas is a major contributor to the greenhouse effect.

What is carbon dioxide (COβ‚‚)?

200

Known as the "brain" of the cell, this organelle directs all cell activities.

What is the nucleus?

200

This gas must be taken in so cells can release energy from food.

What is oxygen?

200

This forms when two or more atoms bond together.

What is a molecule?

200

These bundles of information are what give instructions for traits.

What are genes?

200

This human activity releases a lot of COβ‚‚ into the atmosphere.

What is burning fossil fuels?

300

These bean-shaped organelles turn food and oxygen into energy for the cell.

What are mitochondria?

300

These molecules, built from amino acids, help build and repair body parts.

What are proteins?

300

The chemical symbol "Au" represents this element.

What is gold?

300

This molecule is what makes up genes.

What is DNA?

300

This happens when Earth traps more heat than it releases.

What is global warming?

400

This jellylike substance fills the cell and holds organelles in place.

What is cytoplasm?

400

These are the three key molecules your cells need to power your body.

What are glucose, amino acids, and oxygen?

400

The chemical symbol β€œNa” appears on the periodic table. This is the name of the element it stands for.

What is sodium?

400

This is what happens when a change in the DNA sequence causes a new protein to form, which might lead to a different trait.

What is a mutation?

400

These are two major effects of climate change.

What are rising sea levels, more extreme weather (habitat loss, etc.)

500

Plant cells have this stiff outer layer that animal cells do not.

What is the cell wall?

500

This molecule is a long strand of glucose that must be broken down to be used by the body.

What is starch?

500

A molecule of glucose has the formula C₆H₁₂O₆. This is how many total atoms are in one glucose molecule.

What is 24?

500

This is how a gene can cause a trait, like curly hair or dimples.

What is by giving instructions to make a protein that causes the trait?

500

This is one action people can take to slow climate change.

What is switching to renewable energy sources? (Or reducing methane from meat production, etc.)
