The okapi is an animal known to ancient Egyptians. Soon after being discovered by Europeans an ancient carved okapi image was found in Egypt. Europeans in Africa had for years heard about an animal that they called the African unicorn.
The cell is the smallest living component of organisms and is the basic unit of life. In multicellular living things a collection of cells that work together to perform similar functions is called a tissue. Various tissues that perform coordinated functions form organs.
And organs that work together to perform general processes form body systems. Animals are multicellular eukaryotic organisms that are capable of voluntary spontaneous movements often in response to sensory input. Animal cells are differentiated from cells of other eukaryotes in that they do not have cellulose-containing walls.
It is meant to be a provocation and a stimulus to thought regarding humanitys relationship with nonhuman animals. Alain Elkann Interviews Alain has been writing a weekly interview column for the Italian newspaper La Stampa since 1989. Welcome to the KidzSearch Encyclopedia.

Cell Envelope External Structures of Animal Cells. Some animal and protozoan cells have this sticky outer layer anchored to the plasma membrane. Gycocalyces help animal cells stick to each other and protect cells from dehydration.
This layer is not present in eukaryotic cells that have a cell wall such as plants algae and fungi. Most animal cells are between 10 and 20 micrometers across. A micrometer is one millionth of a meter or one thousandth of a millimeter.
In other words most animal cells are very small. Although most animal cells are far too small to be seen without a microscope some are much larger. The human egg cell for example is visible to the naked eye.
