In general, plant cells vary from 10 to 100 micrometers, depending what type of plant is being studied. Plant cells are often larger than animal cells, which generally range from 10 to 30 micrometers. Ten micrometers are equivalent to 0.001 centimeters, and 100 micrometers are equivalent to .01 centimeters.
While size of plant and animal cells differ greatly, both cells are extremely similar in many ways. The major differences are what the cells use for energy and how energy is produced. Plant cells use the sun for energy, which is converted to energy through photosynthesis. Animal cells rely on food for energy, which is converted by the mitochondria of the cell.
