Cell Theory
Robert Hooke
Which organelle is the powerhouse of the cell?
Is a bacteria a prokaryote or eukaryote?
Prokaryote
What does a microscope do?
Magnifies things
True or False. A plant cell has a cell membrane.
True
Living
What is one thing that the nucleus does?
Control center
Has DNA
Makes ribosomes
Has nucleolus
Name two examples of prokaryotes.
Bacteria and Archaea
Light
Electron (SEM, TEM)
Name a structure that is found in plant cells, but not animal cells.
Large vacuoles, chloroplasts, cell wall
Which scientist "coined" the word cells?
Robert Hooke
What is the clean-up organelle for the cell?
Lysosome
What is one difference between prokaryotes and eukaryotes?
Prokaryotic cells do NOT have a nucleus, their DNA is circular and floats in the cytoplasm
Eukaryotic cells have a nucleus with DNA and have organelles
Electron
Describe the shape of animal cells compared to plant cells.
Animal cells are more rounded, blob-like. Plant cells have a more definite shape, like a square or rectangle.
Which scientist developed the Cell Theory?
Theodore Schwann
What does the Golgi Apparatus do?
Processes, packages and secretes proteins
What does the name Eukaryote mean?
True nucleus
Which type of microscope can view atoms?
Electron or Scanning Probe Microscopes
Animal
What does the Cell Theory state? (3 parts)
1. Every living organism is made of one or more cells.
2. The cell is the basic unit of structure and function of living things.
3. All cells arise from pre-existing cells.
Where are the ribosomes made at?
In the Nucleolus
Give an example of a Eukaryotic cell
Plants
Animals
Fungi
Protists
What is the part of the microscope called where you place the slide you want to observe?
The stage
Compare and contrast vacuoles in plant and animal cells.
Large and few vacuoles in plants. Small and many in animals.
