algae-plant like protists
diatoms
they are photosynthetic autotrophs and they use chlorophyll and carotenoids as pigments
They store food as oil, making them a nutritious food source and float in water
their cell walls are composed of silica
characteristics of algae:
Algae are plantlike protists that contain photosynthetic pigments.
Algae differ from plants because they do not have structures typical of plants.
Many algae have chlorophyll as their main photosynthetic pigment, and also pigments help them absorb light at different wavelengths.
dinoflaellates
they are phylum pyrrophyta
they are unicellular with two flagella at right angles to one another making the dinoflagellate to spin as it moves
they have cell walls made of cellulose
Some are autotrophic, some are heterotrophic
Some are bioluminescent, meaning they emit light
euglenoids
unicellular plantlike protists
contain characteristics of both plants and animals
most euglenoids photosynthesize, but do not have a cell wall; they can also be heterotrophs
chrysophytes
they are yellow-green or golden-brown algae
they have carotenoids as a photosynthetic pigment
most chrysophytes are unicellular, but some are colonial which means they are group of cells that join together and form a close association
brown algae
their color comes from secondary pigment called fucoxanthin
includes all species of kelp
it is multicellular
green algae
can be unicellular, multicellular, or colonial
have cell walls
store food as carbohydrates
photosynthetic organisms
red algae
