What Is the Size Order of Atoms, Electrons, Molecules, Organelles, and Cells?

In summary, an atom is the smallest component of an element, while a molecule is the simplest structural unit of an element or compound. A cell is the basic unit of all organisms, and an organelle is a specialized part of a cell. Electrons are elementary particles with a negative charge. In compound light microscopes, we can see cells and organelles, but atoms, molecules, and electrons are too small to be visible.

Homework Statement


4. atom, cell, electron, organelle, molecule. Define each of these terms and list them according to size from smallest to largest. Which of these, if any, are visible in the compound light microscopes we use in lab?

Homework Equations


The Attempt at a Solution


largest to smallest:
cell - the basic structural and functional unit of all organisms
organelle - a specialized part of a cell; analogous to an organ
molecule - the simplest structural unit of an element or compound
atom - the smallest component of an element having the chemical properties of the element
electron - an elementary particle with negative charge
is this right?

yup. Your definition of molecule and atom could be a little more precise/clear.

1. What are the different sizes of particles in biology?

There are three main categories of particles in biology: macromolecules, organelles, and cells. Macromolecules, such as proteins and DNA, can range from 1-100 nanometers in size. Organelles, such as mitochondria and ribosomes, range from 1-10 micrometers. Cells, the basic unit of life, can range from 10-100 micrometers in diameter.

2. Why is the size of particles important in biology?

The size of particles in biology is important because it determines their function and interactions with other particles. Smaller particles, such as enzymes and hormones, can easily move and interact with other molecules, while larger particles, such as cells, have more complex functions and interactions.

3. Can particles in biology change size?

Yes, particles in biology can change size depending on their environment and function. For example, cells can shrink or expand in response to changes in their surroundings, and macromolecules can fold or unfold to perform different functions.

4. How are the sizes of particles in biology measured?

The sizes of particles in biology are measured using various techniques, such as microscopy, electrophoresis, and spectrophotometry. These methods allow scientists to visualize and analyze the size and shape of particles at different scales.

5. How does the size of particles in biology impact the human body?

The size of particles in biology plays a crucial role in human health and disease. For example, the size and shape of red blood cells can affect their ability to transport oxygen, and the size of viruses can determine their ability to infect cells. Additionally, understanding the size of particles in biology is important for drug delivery and developing treatments for various diseases.
