silicon

phycology

study of algae

Cladophora vagabunda

Chlorophyta (green algae)

The characteristics common to both green algae and plants are

-Food is stored as starch. -Cell walls are made of cellulose.

Algae are not apart of the Plantae kingdom because ...

-They also don't have differentiated cells. -different reproduce features -no vascular tissue

Select reasons why members of phyla Acrasiomycota, Myxomycota, and Oomycota not classified in the kingdom Fungi.

-When present, the cell walls are composed of cellulose. -At some point in their life cycle, these species are motile.

In the past, euglena have been classified as a protozoan because they have:

-motility -no cell wall -pellicle

a red pigment found in red algae and in few cyanobacteria

aethalium

a spore bearing structure of plasmoidal slime mold

Eugleniod movement

a worm like movement of euglena, accomplished by expanding and contracting the entire cell.

The function of the flagellum that remains in the sulcus is to

act as a rudder

In plasmodial slime molds, the plasmodium transforms into reproductive stage called a(n) __________.

aethalium

kelp forest

an undersea ecosystem similar to a land forest

kelp

any one of certain large, tough, brown seaweeds, which are a source of potassium, iodine, algin, and sodium carbonate
