Anton van Leeuwenhoek
Which type of electron microscope scans the surface of a cell and produces a 3D image?
SEM (Scanning Electron Microscope)
Bacteria are an example of what type of cell?
Prokaryotic
What organelle packages molecules from the ER and sends them throughout the cell?
Golgi apparatus
What structure is found outside the plasma membrane of a plant cell and provides structure?

Name one of the three parts of the Cell Theory.
All living things are made of cells
cells are the basic unit of structure of an organism
cells arise from other existing cells
Which type of electron microscope transmits electrons through a specimen to show its internal structures?
TEM (Transmission Electron Microscope)
Give two differences between prokaryotic and eukaryotic cells.
Prokaryotic cells have no nucleus and no membrane-bound organelles
eukaryotic cells have a nucleus and membrane-bound organelles.
What organelle generates energy for the cell in the form of ATP?
Mitochondria
What organelle captures light to create energy and contains chlorophyll?
Chloroplast
According to Cell Theory, where do new cells come from?
Other existing cells
Which microscope would be best for viewing the 3D surface of a cell?
SEM (Scanning Electron Microscope)
A cell is large, has a nucleus, and contains membrane-bound organelles. Is it prokaryotic or eukaryotic? Explain.
Eukaryotic, because it has a nucleus and membrane-bound organelles.
What organelle breaks down old and worn-out parts of the cell, as well as viruses and bacteria?
Lysosome
What are the disk-like structures inside chloroplasts that trap light?
thylakoids
