The only way to see cells is with a microscope. The earliest scientist had to use a rather primitive one.

Which scientist discovered that all animal cells have cells?

Theodor Schwann, a German physiologist, was the scientist who discovered that all animal cells have cells. He made this discovery in the early 19th century as part of his research on cell theory, which he developed alongside Matthias Schleiden.


What organelle would be indicative of a plant cell rather than an animal cell?

A chloroplast would be indicative of a plant cell rather than an animal cell. Chloroplasts are responsible for photosynthesis, converting sunlight into glucose, and are found in plant cells but not in animal cells.


What impact did animal cells have on cell research?

They helped for testing. scientists could test on the animals cells rather than human cells.

Are animal cells flat?

Animal cells come in a variety of shapes, depending upon their specialized function. Epithelial cells are rather flat. Muscle cells are not flat, they are more tubular in shape. While blood cells are roundish. And so forth.


What scientist studies growth and reproduction of cells?

A scientist who studies the growth and reproduction of cells is typically a cell biologist or a molecular biologist. They investigate how cells divide, differentiate, and proliferate, as well as the mechanisms underlying these processes. Their research can have applications in fields such as cancer biology, regenerative medicine, and developmental biology.


Why are plant cells selected to demonstrate plasmolysis rather than animal cells?

Plant cells are selected to demonstrate plasmolysis because they have a cell wall that maintains the structure of the cell even when the cell membrane shrinks due to water loss. Animal cells do not have a cell wall, so they would burst instead of undergoing plasmolysis in a hypertonic solution.


What cell characteristics should the scientist examine to tell whether the organism is an animal or plant?

First of all, a scientist would look at the cell of the organism. Plant cells have thick cell walls surrounding their membrane and typically have a large central vacuole and chloroplasts while animal cells lack chloroplasts, cell walls, and vacuoles. Another difference is that during mitosis, The Golgi Body disappears for most of the process in animal cells, but curiously remains present the entire process in plant cells. In addition, cytokinesis is different in both types of cells and plant cells do not use centrioles during mitosis.


What scientist looked at animal parts an discovered that they were made of cells?

Theodor Schwan in 1839.He also contributed in building cell theory.
