Graphing y = (x - h)2 + k. In the graph of y = x 2 , the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point. We can graph a parabola with a different vertex. Observe the graph of y = x 2 + 3 : Graph of y = x 2 + 3.
The Euglena Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis.aramecium Paramecium are unicellular protozoans classified in the phylum Ciliophora (pronounced sill-ee-uh-fore-uh), and the kingdom Protista. They live in quiet or stagnant ponds and are an essential part of the food chain.
This allows the euglena to move through the water in search of food (either sunlight or food particles). Euglena have a mouth where food (bacteria, detritus, other protozoans) collects and is taken into the body in a saclike structure known as a vacuole.The vacuole holds the food throughout the process of digestion.uglena: -Euglenas have two methods of locomotion. They can use their long flagellum, which whips back and forth and propels the euglena, or a structure known as the pellicle. The pellicle, which is made of protein, lies just next to the cell membrane.
