Parts of a cell
This part of the cell controls what goes in and out.
What is the cell membrane
This sugar molecule is the main source of energy for cells.
👉 What is glucose?
These tiny particles are the basic building blocks of all matter.
What are atoms?
This word describes a characteristic that can be passed from parent to offspring.
What is a trait?
This gas is a major contributor to the greenhouse effect.
What is carbon dioxide (CO₂)?
Known as the "brain" of the cell, this organelle directs all cell activities.
What is the nucleus?
This gas must be taken in so cells can release energy from food.
What is oxygen?
This forms when two or more atoms bond together.
What is a molecule?
These bundles of information are what give instructions for traits.
What are genes?
This human activity releases a lot of CO₂ into the atmosphere.
What is burning fossil fuels?
These bean-shaped organelles turn food and oxygen into energy for the cell.
What are mitochondria?
These molecules, built from amino acids, help build and repair body parts.
What are proteins?
The chemical symbol "Au" represents this element.
What is gold?
This molecule is what makes up genes.
What is DNA?
This happens when Earth traps more heat than it releases.
What is global warming?
This jellylike substance fills the cell and holds organelles in place.
What is cytoplasm?
These are the three key molecules your cells need to power your body.
What are glucose, amino acids, and oxygen?
The chemical symbol “Na” appears on the periodic table. This is the name of the element it stands for.
What is sodium?
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?
These are two major effects of climate change.
What are rising sea levels, more extreme weather (habitat loss, etc.)
Plant cells have this stiff outer layer that animal cells do not.
What is the cell wall?
This molecule is a long strand of glucose that must be broken down to be used by the body.
What is starch?
A molecule of glucose has the formula C₆H₁₂O₆. This is how many total atoms are in one glucose molecule.
What is 24?
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?
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.)
