Prokaryotic Cells
They are like sperm
Earthworms don't have eyes, but they do have light-sensitive cells scattered in their outer skin.
Yes, an earthworm is a living thing. It is a type of organism that is made up of cells, grows, reproduces, and responds to its environment. Earthworms play an important role in maintaining soil health and fertility.
The epidermis in an earthworm is the outermost layer of skin that serves as a protective barrier for the organism. It is a thin layer composed of epithelial cells, which can secrete mucus to aid in moisture retention and facilitate movement through soil. The epidermis also contains sensory cells that help the earthworm detect its environment. Overall, it plays a vital role in respiration and protection against pathogens.

Cells were named in the year 1665 by the scientist, Robert Hooke.
If you add salt to an earthworm, it dies because water in it's cells will all leave. The water will move trying to make the amount of salt inside of the cells equal to that outside. That will actually dry out the worm. Often food is packed in salt to preserve it if there isn't another way.
