SOQ 20 – 1. The Fifteen Phyla of Protista: (divided into six groups) 1. Euglenoza – a. Euglenoids – some have chloroplasts and the others are heterotrophic. This is an example of how it is hard to separate the protest kingdom from the animal and plant kingdoms. Reproduction is by cell division, no sexual reproduction. Includes: Euglena: a single celled photosynthetic cell with flagella b. Kinetoplastids: unique, single mitochondrion in each cell. Two types of DNA, mini- and maxi-circles that are responsible for rapid glycolosis. Parasitic – include the Trypanosoma cruzi that is responsible for the African sleepin sickness. 2. Alveolata – locomotion a. Dinoflagellates – photosynthetic unicells with flagella. Live in marine and fresh water environments, some are luminous. Most have a hard outer coat with silica. Cause Red Tides. b. Apicomplexes – spore forming animal parasites. They have a unique arrangement of fibrils, microtublues and vacuoles, etc. at one end of the cell, (ex: Plasmodium) alternates between hosts, and alteration of gemerations is seen. Flourishes in habitats with a bunch of CO2. causes malaria. c.
