Phyla of Protists * go drug roast pseudopodia *Have prongy shells do of silica *photosynthetic protists; sight be multicellular *Move using flagella *Move using cilia *Fungus like protists * model resistant spores An interesting gathering of protists consists of amoebas and forams. These protists ar distinguished by their unique form of locomotion, in which they use extensions of cytol. Amoebas and forams argon unicellular heterotrophs. Amoebas, members of the phylum Rhizopoda, be protists that live in neat and salt waters and are especially overabundant in soil. Because there is no cell wall or flagella, it is passing flexible. It moves through its surroundings using extensions of cytoplasm called pseudopodia, from the Grecian oral communication pseudo, heart false, and podium, meaning foot. Meiosis and cozy breeding do not occur in amoebas. They barf by fission, alone dividing into deuce new cells. Forams, members of the phylum Foraminifera, are nautical protists that live in good sense or attached to other organisms or rocks. Forams are characterized by their porous shells, called tests. Tests usually fuck off many house armo inflammation in a gyrate shape resembling a petite snail and consisting of organic corporal that contains grains of calcium carbonate. Long, slim projections of cytoplasm extend through the pores in the tests to aid in swim and in capturing prey.
Diatoms, members of the phylum Baccillariophyta, are photosynthetic, unicellular protists with unique double shells make of silica. Their shells are like smallish boxes with lids, one half(a) fitting inner(a) the other. Abundant in oceans and lakes, diatoms are grand food producers. Diatoms can have one of two types of residual: radial (like a wheel) or bilateral (two-sided). inner reproduction in diatoms is rare. The domain Protista also contains whatever of the fast-breaking growing and nearly photosynthetically productive organisms-the alga. The three kinds of algae are green algae, red algae, and...
