Paramecium

Paramecium is part of the Alveolata clade, which are heterotrophs and a major clade that belogs to the kingdom Protista. Paramecium are single-celled organisms with an oval, slipper shaped. On the outside of the Paramecium you can find the radiatin canal and a contractile vacuole. The cytoplasm, food vacuoles, the macronucleus, and the micronucleus are located inside. Another characteristic of them is that they move faster than other protists. They live in aquatic environments, but most usual in warm water. Paramecium uses the process phagocytosis to capture their prey. It likes to eat bacteria, dead plant, algae and animal matter. They are able to do sexual and asexual reproduction. Sexual reproduction occurs only under stressful conditions by a process called conjugation. In the other hand asexual reproduction is the most common, but is accomplished by transverse binary fission. Paramecium also plays an important role in the carbon cycle since the bacteria they eat are found in decaying plants. …show more content…
They are unicellular organisms from the kingdom Protista. They move by a flagellum, which is located in the anterior end. They also contain a red eyespot at the anterior end that is able to detect light. Since Euglena lack a cell wall, they contain a pellicle composed of a protein layer. They usually live in quiet puddles or ponds. They have chloroplast that traps sunlight which is used for the process known as photosynthesis. Since Euglena can absorb food from their environment, they are not considered autotrophic completely. When light is not available, they become heterotrophic and for ended up they cannot photosynthesize. When feeding as a heterotroph, Euglena acts by surrounding a particle of food and consumes it by
