most abundant chrysophyta
unicellular of colonial
most of plant plankton
growth more than all land plants in weight |

cell wall 2 halves of silica(like petri dish)
many move by raphe-slits in valves-produces a countercurrent, so they "glide"
store oil not starch |

attach to solid surface-holdfast
stem like- stipe
leaf like- blade
have airbladders to float photosynthetic areas to light |

Rhodophyta
have chlorophyll and red and blue accessory pigments. |

Term
| Red algae characteristics |
|
Definition
red and blue accesory pigmentation allow them to live deep in the water
there is no strong current so the bodies are fragile
many are eaten |
