Cell Theory and Microscopy
What tool/instrument do scientists use to observe cells?
Microscope
What organelles do prokaryotic cells lack?
Membrane-bound organelles
Name the organelle based on the description:
Makes proteins that the cell needs
Ribosomes
Name the organelle based on the description:
Houses most of the cell's DNA and controls the cell's activities
Nucleus
Name the organelle based on the description:
This external structure provides the cell additional protection and is made of cellulose
Cell Wall
What type of microscope is used to study the surface of a specimen?
What kingdoms are part of prokaryotes?
Bacteria and Archaea
Name the organelle based on the description:
A whip-like structure used to help the cell move
Flagella
Name the organelle based on the description:
Selectively permeable; determines what enters and exits the cell
Cell Membrane
Name the organelle based on the description:
This organelle contains chlorophyll (a green pigment) that captures sunlight to make sugar in a process called photosynthesis
Chloroplast
Which scientist observed living microorganisms such as bacteria, blood cells, and even muscle tissue?
Antonie van Leeuwenhoek
What kingdoms are part of eukaryotes?
Protists, Fungi, Plants, and Animals
Name the organelle based on the description:
A region of DNA that is swimming in cytosol
Nucleoid
Name the organelle based on the description:
ships, modifies, and packages materials throughout the cell
Golgi Apparatus
Name the organelle based on the description:
This organelle is large in plant cells and is used to store mostly water, but also proteins and waste products
Central Vacuole
What are the 3 principles of Modern Cell Theory?
1. All living things are made of cells
2. All cells come from pre-existing cells
3. All cells can be different, but share common features
What 4 features do ALL cells have?
1. Cell Membrane
2. DNA
3. Ribosomes
4. Cytosol
Name the organelle based on the description:
A jelly coating that protects the cell and gives it its shape
Capsule
Name the organelle based on the description:
The powerhouse of the cell; makes energy in the form of ATP
Mitochondria
What are the organelles that are in plant cells, but not animal cells?
1. Cell Wall
2. Central Vacuole
3. Chloroplasts
A scientist wants to observe the internal structure of a cell.
What type of microscope should they use?
Transmission Electron Microscope (TEM)
Determine if this organism is prokaryotic or eukaryotic:
1. This organism is unicellular
2. This organism has a region of DNA swimming in cytosol
3. This organism lack membrane-bound organelles
Prokaryotic
Name the organelle based on the description:
Helps the cell stick to surfaces
Fimbriae
Name the organelle based on the description:
This organelle is debated if they are present in plant cells. It is used to break down waste products and damaged organelles.
Lysosome
Algae
