WebApr 7, 2024 · Respiration is the process in which organisms exchange gases between their body cells and the environment. From plants and animals to prokaryotic bacteria, archaeans, eukaryotic protists, fungi, and animals, all living organisms undergo respiration. During normal human respiration, glucose reacts with oxygen to produce the energy needed for ... 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.
