CELL BASICS
This is the smallest unit of life.
What is a cell?
This type of cell has no nucleus.
What is a prokaryotic cell?
This part controls what enters and leaves the cell.
What is the cell membrane?
Known as the powerhouse of the cell.
What is the mitochondrion (mitochondria)?
The human body contains trillions of these.
What are cells?
All living things are made of one or more of these.
What are cells?
This type of cell has a true nucleus.
What is a eukaryotic cell?
This gel-like fluid fills the cell.
What is the cytoplasm?
These tiny structures build proteins.
What are ribosomes?
These blood cells do not have a nucleus.
What are red blood cells?
This scientist first observed cells in 1665.
Who is Robert Hooke?
These two organisms are examples of prokaryotes.
What are bacteria and archaea?
This structure is called the control center because it contains DNA.
What is the nucleus?
This organelle stores water, nutrients, and waste.
What is the vacuole?
These cells can grow up to 3 feet long.
What are neurons (nerve cells)?
Cells are too small to see without one of these.
What is a microscope?
Plants, animals, and fungi are examples of this cell type.
What are eukaryotic cells?
These are the three essential parts found in every cell from the presentation.
What are the cell membrane, cytoplasm, and nucleus?
Mitochondria produce this form of energy.
What is ATP?
Cells constantly do this over time.
What is replace themselves?
Cells are capable of performing these basic life activities.
What are life functions?
Prokaryotic DNA floats freely in this region.
What is the nucleoid?
This structure contains DNA and directs cell activities.
What is the nucleus?
This process is used by mitochondria to make ATP.
What is cellular respiration?
Cells work together to form these three levels of organization.
What are tissues, organs, and organisms?
