Ethnography is the study of social interactions, behaviours, and perceptions that occur within groups, teams, organisations, and communities.
Then the cell divides in half, with one Paramecium above the other, like a short totem pole. Paramecium also reproduce sexually, and this is really weird. Two compatable cells join belly to belly and part of their cytoplasm fuses (kind of like a siamese twin). For sex, they do not need their big macronuclues: it is slowly destroyed.
Our current Paramecium bursaria is in some ways much more interesting. It also undergoes conjugation -- where compatible mating types get side-by-side and exchange genetic material -- but its amazing feature is the presence of those green items inside it.heir cilia sweep food and water into the cell mouth, the food continues into the gullet, and when enough food has collected at the gullet's bottom it breaks away and forms a food vacuole -- a little bubble of food that drifts throughout the cell.
