Bio 1011 Chapter 28 Flashcards
Blade
Thin, flattened section of a plant leaf that collects sunlight
Amoebozoan
A protist in a clade that includes many species with lobe-or tube-shaped pseudopodia
Cercozoan
A amoeboid or flagellated protist that feeds with threadlike pseudopodia.
Endosymbiosis
A relationship between two species in wich one organism lives inside the cell or cells of another organism.
Diatom
Photosynthetic protist in the stramenopile clade, wall silicon dioxide embedded in an organic matrix.
Stipe
A stemlike structure of a seaweed
Amoeba
A protist characterized by the presence of pseudopodia
Holdfast
A rootlike structure that anchors a seaweed.
Rhizaria
many ar known as amoebas characterized by threadlike pseudopodia.
Foram
organic material hardened with calcium carbonate.the pseudopodia that extend through the pores function in swimming.
Alternation of generations
the alternation of two or more different forms in the life cycle of a plant or animal, diploid form sporophyte, and a multicelular haploid
form, the gametophyte.
Green alga
important source of oxygen, provide food for aquatic organisms
Mixotroph
Single-celled protists (eukaryotes) with the ability to get nutrition by phototrophy and heterotrophy
Pseudopodium
temporary projection of cytoplasm, or a ‘‘false foot,” used by some protists for feeding or moving
Brown algae
A multicellular, photosynthetic protist whit characteristic brown or olive, colo from carotenoids.
Dinoflagellate
photosynthetic unicellular with two distinct flagella that rotate as they swim
Opisthokont
A member of an extremely diverse clade of eukaryotes that includes fungi, animals, and several closely related groups of protists.
Apicomplexan
A protist in a clade that includes many species that parasitize animals. Some cause human desiase
Isomorphic
sporophytes and gametophytes look alike, although they differ in chromosome number.
Diplomanad
A protist that has modified mitochondria, two equal[sized nuclei, and multiple flagella.
Algae
primitive chlorophyll-containing mainly aquatic eukaryotic organisms lacking true stems and roots and leaves
Unikonta
one flagella, similar gene sequence and similar myosin proteins
Stramenopila
One of the major subgroups for which the “SAR”eukaryotic is named. includes diatoms and brown algae.
Parabasalid
A protist, such as a trichomanad, with modified mitochondria.
