Foundations
These are the fundamental building blocks of life.
What are cells?
These macromolecules make up your hair, muscles, and enzymes.
What are proteins?
This flexible covering controls what enters and exits the cell.
What is the cell membrane?
This type of transport requires no energy from the cell.
What is passive transport?
This process uses oxygen to break down food for energy.
What is cellular respiration?
This instrument allowed scientists to investigate cells.
What is a microscope?
DNA and RNA belong to this macromolecule group.
What are nucleic acids?
This rigid structure is found in plants but not animals.
What is the cell wall?
Water moving across a membrane is this type of diffusion.
What is osmosis?
This first step in breaking down glucose happens in the cytoplasm.
What is glycolysis?
This scientific idea states that all living things are made of cells.
What is Cell Theory?
Butter, oils, and cell membranes contain these macromolecules.
What are lipids?
This gel-like substance holds organelles in place inside the cell.
What is the cytoplasm?
This process uses a protein channel to help molecules cross the membrane.
What is facilitated diffusion?
When oxygen is not available, cells use this process to make energy.
What is fermentation?
These large molecules—like proteins and lipids—are essential building blocks of life.
What are macromolecules?
Sugars and starches are examples of this macromolecule type.
What are carbohydrates?
This organelle contains DNA and acts like the “control center.”
What is the nucleus?
Because it moves substances from low to high concentration, this transport needs energy.
What is active transport?
Plants use sunlight to make sugar through this process.
What is photosynthesis?
One part of cell theory states that all cells come from these.
What are pre-existing cells?
The organelle in which nucleic acids are primarily located.
What is the nucleus?
This green organelle captures sunlight to make food.
What is the chloroplast?
This is moving particles out of the cell.
What is exocytosis?
This is the location for the second step of cellular respiration.
What is the mitochondria?
