Question

complete the following statements to describe the importance of microscopes.

even though cells are quite complex, they are also quite click to select in size.

because of this, they are often measured in click to select, which are 1000 times smaller than a millimeter (mm), or in click to select, which are 1,000,000 times smaller than a millimeter!

plant and animal cells are approximately 10-100 \\(\mu\text{m}\\) in size and can be viewed using click to select microscopes.

proteins and viruses are approximately 10-100 nm in size and require click to select microscopes to view.

Explanation:

Analyze cell sizes and units

Using the Eukaryotic Cells and Prokaryotic Cells knowledge points

• Most eukaryotic cells (plant and animal cells) range from \(10\text{ to }100\ \mu\text{m}\) in size.
• Most prokaryotic cells (bacteria) are smaller, typically \(1\text{ to }10\ \mu\text{m}\).
• Cells are extremely small, meaning they are quite small in size.

Determine metric conversions

Using the Microscopy Principles knowledge point

• A micrometer (\(\mu\text{m}\)) is \(10^{-6}\text{ m}\), which is \(1,000\) times smaller than a millimeter (\(10^{-3}\text{ m}\)).
• A nanometer (\(\text{nm}\)) is \(10^{-9}\text{ m}\), which is \(1,000,000\) times smaller than a millimeter (\(10^{-3}\text{ m}\)).
• Therefore, cells are often measured in micrometers, which are \(1,000\) times smaller than a millimeter, or in nanometers, which are \(1,000,000\) times smaller than a millimeter.

Match specimens with microscope types

Using the Microscopy Principles knowledge point

• Plant and animal cells (\(10\text{ to }100\ \mu\text{m}\)) are within the resolving power of standard light microscopes (limit of resolution \(\approx 0.2\ \mu\text{m}\)). Thus, they can be viewed using light microscopes.
• Proteins and viruses (\(10\text{ to }100\text{ nm}\)) are below the resolution limit of light microscopes and require the much higher resolution of electron microscopes. Thus, they require electron microscopes to view.
