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.
They are not completely autotrophic though, euglena can also absorb food from their environment; euglenas usually live in quiet ponds or puddles. Euglena move by a flagellum (plural â flagella), which is a long whip-like structure that acts like a little motor.The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.It is attached at an inward pocket called the reservoir. The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food).he flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.
