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.
Euglena are small organisms in the Protist Kingdom. Euglena gracilis is just one of many species of Euglena. They do not have common names like birds or trees, so we have to refer to them by their scientific name. Euglena are interesting because they are a sort of combination of plant and animal.They can make their own food like a plant, but they can also eat other things, like an animal.uglena gracilis and other euglena are green because they eat green algae. They keep the algae inside their bodies and use it to make their own food.
