Phyla of Protists * break drug nuisance pseudopodia *Have prongy shells do of silica *photosynthetic protists; great deal be multicellular *Move using flagella *Move using cilia *Fungus like protists * gain resistant spores An interesting convocation of protists consists of amoebas and forams. These protists ar distinguished by their unique form of locomotion, in which they use extensions of cytoplasm. Amoebas and forams argon unicellular heterotrophs. Amoebas, members of the phylum Rhizopoda, argon protists that live in neat and salt amnionic fluid and are especially rampant in soil. Because there is no cell wall or flagella, it is passing flexible. It moves through its milieu using extensions of cytoplasm called pseudopodia, from the classic oral communication pseudo, core false, and podium, meaning foot. Meiosis and versed breeding do not occur in amoebas. They chuck by fission, alone dividing into devil new cells. Forams, members of the phylum Foraminifera, are marine protists that live in mainstay or attached to former(a) organisms or rocks. Forams are characterized by their porous shells, called tests. Tests usually convey many house arrange in a coil shape resembling a bantam snail and consisting of organic actual that contains grains of calcium carbonate. Long, slim projections of cytoplasm extend through the pores in the tests to aid in fluent and in capturing prey.
Diatoms, members of the phylum Baccillariophyta, are photosynthetic, unicellular protists with unique double shells do of silica. Their shells are like bantam boxes with lids, one half(a) fitting wrong the other. Abundant in oceans and lakes, diatoms are grand food producers. Diatoms can have one of deuce types of residual: radial (like a wheel) or bilateral (two-sided). inner reproduction in diatoms is rare. The domain Protista also contains roughly of the fast-breaking growing and most photosynthetically productive organisms-the algae. The three kinds of algae are green algae, rose-cheeked algae, and...
