Transcript
  • Water molds, Hypochytrids - groups superficially similar to fungi
  • Bicosoecids - a small group of heterokont flagellates
  • Labyrinthulids, Thraustochytrids - small groups similar to slime molds
  • Proteromonads, Opalines - small groups of flagellates

Reproduction

Sexual reproduction and auxospore formation

Structure form and function

They have two flagella of different length one at the front of the cell, and one attached further back.

The front flagellum has tiny, three-part forked brstles running along each side

This flagellum beats out a water current which moves the cell forward and food back to the cell

The rear flagella is smooth, and has a whip-like motion.

The Stramenopiles are a very large algal kingdom presently included in the Chromalveolata.They range in size from single-celled diatoms to giant multicellur kelp.

Ecological Roles

Photoautotrophs, some forming harmeful blooms

Heterotrophic decomposers; producers of seagrass wasting disease and form deepsea deposits

Their Diet

Stramenopiles can be nonphotosynthetic or photosynthetic

Photosynthetic stramenopiles have chlorophyll

Nonphotosynthetic stramenopiles store their food as lipids and fatty acids

Stramenopiles

The stramenopiles are a major group of eukaryotes, including the heterokonts and a few close relatives. These are distinguished by having tripartite mastigonemes, or are secondarily derived from forms that do. In addition to the heterokont algae, they include the following:
