Algae

Algae are a small and diverse group of organisms. There are more than 7,000 species in several different habitats. Like plants, algae contain chlorophyll. Unlike plants they are primarily aquatic. Because they are aquatis, and manufacture their own food, they get the name algae. Algae are photosythetic organisms that occur in most areas. They vary from small, single-celled forms to complex multicellular forms, such as the giant kelps that grow to 65 meters in length. Algae are classified by their pigments: Brown, Red, and Green.

Trypanosomes

Any of various parasitic flagellate protozoans of the genus Trypanasoma, transmitted to the vertebrate bloodstream, lymph, and spinal fluid by certain insects and often causing diseases such as sleeping sickness and nagana. The parts of a trypanosome cell are kinetoplast, acidocalcicome, glycocome, cytosckeleton, receptors, and cell cycle. They have many different parts.

Paramecia

Paramecia move with the assistance of small hairs called cilia which project from all sides of its body. Almost any sample of fresh water or scum will contain some paramecia, which can be seen with a low powered microscope or magnifying class. They are single celled. They are also shaped like a slipper. To gather its food, the paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. most common, they reproduce asexually, but they are also capable of reproducing sexually.

Diatoms

Diatoms are mostly unicellular. Diatoms are found in soils, or moist mosses. They have silicone, sharp shells. Diatoms divide in half until they get too small. They can live in both freshwater and marine ecosystems, and they contain chlorophyll. Many cling to surfaces such as aquatic plants, molluscs,crustaceans, and even turtles. Whales may carry growths of diatom on their skin. They are also autotriphic.
