1 Euglenophyta Brisson Lam 10B

2 What is it? Euglenophyta is in the kingdom Protista, consisting of mostly unicellular aquatic algae. Most live in freshwater; many have flagella and are motile. Possess both animal and plant characteristics.

3 The outer part of the cell consists of a firm but flexible layer called a pellicle, or periplast, which cannot properly be considered a cell wall.

4 Some euglenoids contain chloroplasts that contain the photosynthetic pigments chlorophyll a and b; others are heterotrophic and can ingest or absorb their food.

5 Reproduction occurs by longitudinal cell division.
A good recipe for a medium in which to grow Euglenozoa is in the laboratory calls for boiling an extract of horse manure. 

6 The most characteristic genus is Euglena, common in ponds and pools, especially when the water has been polluted by runoff from fields or lawns on which fertilizers have been used.

7 Kinetoplastids: parasitic forms, e. g
Kinetoplastids: parasitic forms, e.g. Trypanosoma: Causes African sleeping sickness; transferred by tse-tse fly
