Document Summary

Protists > a) unicellular b) multicellular c) heterotrophic. Unicellular:: euglenophyta, cryptophyta, dinophyta (dinoflagellates, haptophyta, bacillario phyta (diatoms) [heterokont, chrysophyta [heterokont] By pigment [chlorophyll type [a, b, c, d etc]; carotenoid; bilin] By cell wall: things do change faster than we die due to phylogeny, within the protists, the complexity is much higher. Appeared approx 2000 million years ago: protist diversity- think of it in terms of classification, which groups are which, use a couple of techniques. Simplest one is on the basis of colour. Basically on pigment- have chlorophyll which have different types. Mostly concerned with a, b and c in regards to protists. Allows us to separate clades of protists based on difference in pigments. Chl a has a methyl and chl b has an aldehyde. No selective advantage for having a methyl or an aldehyde. Defines protists groups based on pigment: another thing that differentiates protist groups are the carotenoids. Beta carotene- purple; fucoxanthin- brownish colour; siphenaxanthin; peridinin.
