The most important things for a cell<span> are oxygen in order to respire and Glucose, also for respiration. This is used in a process called glycolysis where the </span>cell<span> makes a chemical called ATP which is basically our energy
These are macrophytes that grow entire in the freshwater and become fossilized by the calcification oozes, going back to the Paleozoic era about 250 million years ago.
And they are unicellular to multi-cellular organisms also found in moist terrestrial habitats.
