algae - plantlike protists
characteristics of algae
plantlike protists
contain photosynthetic pigments
they do not have roots, leaves or other structures typical of plants
algae have chlorophyll as their main photosynthetic pigment
Diatoms
photosynthetic autotrophs
use chlorophyll and carotenoids as pigments.
store food as oil
cell walls are composed of silica
reproduce both sexually and asexually
Dinoflagellates
Phylum Pyrrophyta
unicellular
cell walls made of cellulose
autotrophic/ heterotrophic
bioluminescent- emit light
dinoflagellate algal bloom
Red tides can be harmful to humans
The toxin is ingested by shellfish, which is ingested by humans
The ecosystem is affected through reduced light penetration, toxin levels, and reduction in primary producers to the food web.
Euglenoids
Phylum Euglenophyta
unicellular plantlike protists
photosynthetic
do not have a cell wall
can be heterotrophs
Chrysophytes
yellow-green or golden-brown algae
have carotenoids as a photosynthetic pigment
unicellular
Brown algae
They get their brown color from fucoxanthin
They are some of the largest multicellular plantlike algae
Green algae
photosynthetic
unicellular, multicellular, or colonial
have cell walls
store food as carbohydrates
