one-celled การใช้

• Protozoa one - celled creatures that invade the body cavities : entamoeba histolytica ; entamoeba coli
• A one - celled animal or plant cannot , of course , survive the destruction of its one cell
• Life began , men think , in the salty sea , near the land , where the waters were not deep , very small one - celled organisms came into being
• In short , all living things are developments from these one - celled organisms . they have developed step by step through change upon change from these first , simple , living things
• Many , though not all , terrestrial prokaryotes ( simple one - celled organisms such as bacteria that lack a membrane - bound nucleus ) and eukaryotes ( organisms with well - defined nuclei ) could survive this temperature range
