Nitella pseudoflabellata is a genus of alga found in freshwater classed under the family of characeae and is commonly found along river beds, paddy fields as well as sandy water diches (KANAHORI, 1971). Nitella pseudoflabellata is a commonly used in laboratory due to the large cells that they carry, and the ease of cultivation in a laboratory environment (Urbaniak, 2009). Nitella has many similarities with other organisms that undergo cytoplasmic streaming. Cytoplasmic streaming which is also known as protoplasmic streaming, is the movement of cytoplasm which is a fluid like substance inside an animal or plant cell (Casanova, 2009). Cytoplasmic streaming was first identified in the early 1830s and helped biologists to understand the biological fundamental units for life to occur (Kishimoto, 1966). The cause of cytoplasmic streaming in plants is often to move chloroplast around the cells. Chloroplast is what enables the plants to absorb sunlight and uses it to create a source of energy and sugars (Tazawa, 1989). In addition to this the organelles that use this are ones that need protein and mitochondria such as ribosomes which are mainly for energy production, where as it is also needed for protein excretion which is important for the Golgi apparatus (Fichter and Green, 1986).
