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.
Plant-like protists. Another type of protist are ones that are plant-like, meaning they can make their own food. One example of that is algae. An example of a unicellular algea is called the euglena. The euglena can produce its own food like a plant with the help of the eyespot, which can direct it to a light source.But what's interesting is that the euglena can also search for food if light is not available.he euglena can produce its own food like a plant with the help of the eyespot, which can direct it to a light source.
