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.
From Wikipedia, Euglena is a genus of unicellular flagellate protists.. The key to why they're not considered plants or animals is in the word unicellular, which means the entire organism consists of one cell.n order to be classified as a plant or animal, an organism has to be multicellular, or made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls. Thereâs no cell wall around a Euglenaâs cell membrane, so it is a protozoan.
