Biology notes on the "Phyla of Protists." This Phyla includes algea, protists, sponges, etc.

Phyla of Protists * drive drug abuse pseudopodia *Have prongy shells make of silica *photosynthetic protists; can be multi kioskular *Move development flagella *Move using cilia *Fungus like protists *Form resistant spores An interesting group of protists consists of amoebas and forams. These protists ar distinguished by their extraordinary form of locomotion, in which they use extensions of cytoplasm. Amoebas and forams argon unicellular heterotrophs. Amoebas, members of the phylum Rhizopoda, atomic number 18 protists that live in neat and salt waters and argon especially abundant in soil. Because there is no cell wall or flagella, it is passing flexible. It moves through its environment using extensions of cytoplasm called pseudopodia, from the Greek oral communication pseudo, implication false, and podium, meaning foot. Meiosis and sexual breeding do not issue forth in amoebas. They reproduce by fission, alone dividing into two unexampled cells. Forams, members of the phylum Foraminifera, are marine protists that live in sand or attached to other organisms or rocks. Forams are characterized by their holey shells, called tests. Tests usually fill many house arrayed in a spiral shape resembling a tiny escargot and consisting of organic material that contains grains of calcium carbonate. Long, slim projections of cytoplasm offer through the pores in the tests to aid in swimming and in capturing prey.

Diatoms, members of the phylum Baccillariophyta, are photosynthetic, unicellular protists with unique double shells made of silica. Their shells are like small boxes with lid s, one half(a) fitting inside the other. o! verabundant 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). Sexual reproduction in diatoms is rare. The kingdom division Protista also contains some of the fast-breaking growing and most photosynthetically cultivable organisms-the algae. The three kinds of algae are green algae, red algae, and...
