Prokaryotic cells are unicellular organism of the domain prokaryotes and archaea. These cells lacks cell organelles however other components such as plasma membrane, cytoplasm and DNA. The size of the prokaryotic cell ranges between 0.1 to 5.0 µm.
On other hand eukaryotic cells also contain cellular structure like plasma membrane DNA , cytoplasm but also include true nucleus and other cell organelles that are double membrane bounded. The average cell size of these cells are tend to be - 10 to 100 of the cell size
Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
