Unicellular Organisms 'Diatoms' Unique Patterns

Diatoms are part of the stramenophile clade and they are unicellular organisms that have unique appearances or shapes because of their cell wall. Diatoms have silica cell walls, which are pieced into two halves put together. The silica cell walls are similar to glass and they are responsible for the Diatoms’ unique patterns. Diatoms have different pigment that aid in the process of photosynthesis. The pigments that are present in Diatoms are chlorophyll a, chlorophyll c, and xanthophyll. Since Diatoms are photosynthetic they play a major role in marine life as photosynthetic producers.

Paramecium is part of the alveolates clade, which is a clade that has sacs called alveoli to support the structure of the cell. The Paramecium is a freshwater
bacteria and is hypertonic to the environment they are in. Since the Paramecium is hypertonic to the environment they are in they have to release excess water and they excrete the water via the contractile vacuoles. Paramecium is part of the group ciliates because of the cilia that is present at the exterior of the cell. The cilia are hair-like projections that helps the Paramecium move by locomotion. The Paramecium has a macronucleus that controls the cell’s activities and the micronucleus that is responsible for reproductions via fission. The Paramecium engulfs their food from the oral groove via endocytosis and excretes the waste with the anal pore. The diagram shown is shows the structures of the Paramecium.
