Do any cell have natural color?
Are cells specific colors or can they be any color? In nature, most cells are transparent and without color. Animal cells that have a lot of iron, like red blood cells, are deep red. Cells that contain the substance melanin are often brown.
Can cells see?
The ability of cells to aggregate inside unlighted incubators suggested that aggregation signals involved light in the near-infrared range. Thus, the author proposed that cells are able to detect each other through scattered near-infrared light and to use this information to direct their movements.
Which is smallest cell?
The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich. The longest cell is the nerve cell.
Where are cells found?
Living cells are found everywhere on this planet unless the area is sterile. Run your fingers along a smooth wooden fence (even wood is composed of dead plant cells) and you will pick up cells of pollen, fungal spores, bacteria and probably green algae.
Why are cells called cells?
Cells got their name from an Englishman named Robert Hooke in the year 1665. He first saw and named “cells” while he was experimenting with a new instrument we now call a “microscope.” These tiny boxes reminded him of the plain small rooms that monks lived in called “cells”.
Where do cells travel?
In tissues, cells travel through microscopic scaffolding, called the extracellular matrix (ECM), changing their shapes and following tracts in a seemingly purposeful way. Wittmann has just made a key discovery of a molecular process that is a lynchpin in permitting the directional movement of cells.
What are the parts and functions of a cell?

What is cell theory?
Definition of cell theory : a theory in biology that includes one or both of the statements that the cell is the fundamental structural and functional unit of living matter and that the organism is composed of autonomous cells with its properties being the sum of those of its cells
