Euglenophytes Euglenophytes are plantlike protists that have two flagella and no cell wall. Eukaryotic Organisms from phylum Euglenophyta Closely related to animal like flagellates (zooflagellates) Typical size: 50 micrometers What are Euglenophytes ?

Euglenophytes Eyespot Used to locate sunlight Chloroplast Used for photosynthesis Flagella Usually come in pairs The longer one propels the flagella through the water Pellicle Maintains shape Tough and flexible Paramylon bodies Used to store carbohydrates Mitochondria ATP production Contractile vacuoles Discharges water from the cell to avoid bursting Nucleus Contains DNA Cytostome A “mouth” used for food ingestion when there is lack of sunlight Structures

Euglenophytes Habitat Nutrition Euglenophytes typically live in freshwater all throughout the world. Capable of photosynthesis They use their eyespot and chloroplasts. When there is lack of sunlight, they eat bacteria or other material through their cytostome Can store carbohydrates in small storage bodies

Euglenophytes Euglenophytes reproduce asexually. They go through a process of longitudinal binary fission Longitudinal binary fission starts from the front end of a cell. Reproduction

Euglenophytes Often found in locations having lots of mineral and organic nutrients. This means it has a lot of plants and algae (eutrophic). Ditches and ponds near cow pastures, hog lots, chicken farms, etc. Thick green or red scum on water surfaces is often from euglenoid colonies Mud flats (another nutrient-rich environment) usually have euglenoids Very few euglenoids have been grown in axenic culture(a pure culture of microorganisms), and euglenoid culture media are generally very nutrient rich Ecology

Euglenophytes Euglena Most species of Euglena have photosynthesizing chloroplast within the body of the cell, which enables them to feed themselves (autotrophy). However, they can also take nourishment heterotrophically. Trachelomonas They have shell-like covering called lorica, which can be spherical, elliptical, and pyriform (pear-shaped) and have a diameter within the range 5 to 100 µ. The lorica surface colors would fall around hyaline, yellow, or brown. Phacus light-green and propel them selves by gyrating their body. They have a flagellum which is often a long as their bodies.
