Protist Lineages exam Flashcards

A major group of unicellular eukaryotes, many of which lack mitochondria and reproduce asexually.

They lack mitochondria, have two nuclei, and use flagella for motion.

A group of protists that lack mitochondria and use flagella for movement, often parasitic.

An organism that can perform both photosynthesis and heterotrophy.

A major monophyletic group of eukaryotes that includes green algae and land plants, originating from primary endosymbiosis.

Phycoerythrin, which masks the green from chlorophyll.

A group of algae similar to land plants, containing chlorophytes and charophytes.

A monophyletic supergroup made up of Stramenopiles, Alveolates, and Rhizarians.

A group of protists characterized by flagella with hair-like projections, includes diatoms and brown algae.

Unicellular photosynthetic organisms with protective shells made of silicon dioxide.

Unicellular organisms with yellow and brown carotenoids, often mixotrophs.

To help the kelp stalks float to the surface for better sunlight exposure.

A group of protists with membrane-enclosed sacs (alveoli) under the plasma membrane.

Mostly unicellular aquatic protists with two flagella and cellulose plates.

Parasitic protists with apical complex structures for host cell penetration.

It involves both sexual and asexual reproduction, switching between mosquitoes and humans.

Protists covered in cilia used for movement and feeding, with a diploid micronucleus and macronucleus.

By exchanging haploid micronuclei and undergoing mitosis to form new macronuclei and micronuclei.

Mostly unicellular amoebas that use pseudopodia for feeding.

Protists with an internal silica skeleton and pseudopodia for feeding.

Protists with calcium carbonate shells that have holes for pseudopodia.

A group of amoeba and flagellated protists that feed with pseudopodia.

A group of amoebas with lobe and tube-shaped pseudopodia, including slime molds.

A large, continuous cell with many nuclei that forms fruiting bodies.

Slime molds that form fruiting bodies by aggregating individual cells.

They highlight the evolutionary diversity and complexity of eukaryotic life forms.
