Question

Today, scientists can study human cells grown in petri dishes. Explain how this technique builds on the work of early scientists.

Answer 1

  Back then, when scientists just found out that cells made every living thing, they wanted to concentrate on the many types and variation of a cell. They did this by isolating the cell in a petri dish, and it is still used today. I'm not sure if this is the answer you were looking for.

Answer 2

The Petri dish can be used to grow and isolate different cell types and thus study their functions and characteristics.

• According to the cell theory, the cell can be considered the fundamental unit of all living things.

• A Petri dish is a shallow dish made of glass that scientists use to develop a growth medium where different cell types can be cultured.

• Scientists have been capable of isolating different cells by using Petri dishes, thereby enabling the discovery of the relationships between cell types and their respective functions.

• The Petri dishes can also be used to achieve the self-assembling of cells and create cell clusters that can be transplanted into the body.

• Scientists have recently developed the first human embryo model (blastocyst) in a Petri dish.

In conclusion, the Petri dish can be used to grow and isolate different cell types and thus study their functions and characteristics.
