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

  2. Euglenophytes • Structures • 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 cellto avoid bursting • Nucleus • ContainsDNA • Cytostome • A “mouth” used for foodingestion when there is lack of sunlight

  3. 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 eatbacteria or other material through their cytostome • Can storecarbohydrates in small storage bodies

  4. Euglenophytes • Reproduction • Euglenophytesreproduce asexually. • They go through a process of longitudinalbinary fission • Longitudinal binary fissionstarts from the front end of a cell.

  5. Euglenophytes • Ecology • 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

  6. Euglenophytes • Examples • 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.
