How do unicellular organisms respire
WebIndividual cells, such as bacteria, do not have skulls or brains. However, individual cells may seem to have brains because they can perform complicated activities on their own. Like brains, they can receive information and respond to it. Answer 3: The short answer is that cells do not have brains. Brains are made of many nerve cells (neurons). WebIn some unicellular eukaryotic organisms such as the amoeba, shown in Figure 22.9, cellular wastes and excess water are excreted by exocytosis, when the contractile vacuoles merge with the cell membrane and expel wastes into the environment. Contractile vacuoles (CV) should not be confused with vacuoles, which store food or water. Figure 22.9.
