Protists

Binary fission

________ is a type of asexual reproduction typically observed in prokaryotes and a few single- celled eukaryotes.

Photosynthetic protists

________ make up a large portion of phyto- plankton found near the surface of oceans and lakes.

Protists

________ known as zooxanthellae provide most of the coral's energy needs by photosynthesis.

Kelp forests

________ provide shelter for many marine species, and the kelp itself is a source.

Paramecium

________ has two kinds of nuclei, one is a large ellipsoidal nucleus called a macronucleus and other is (at least) one small nucleus called a micronucleus.

ancestors of todays

Animals, plants, and fungi evolved independently from the ________ protists.

eukaryotes

All ________ evolved from prokaryotes.

intestinal disease Trypanosoma

Are responsible for serious, and sometimes deadly outbreaks of ________ cause African sleeping sickness.

Water molds

________- and many other protists- reproduce asexually by producing spores in a structure called a sporangium.

fungi

Plants, animals, and ________ evolved from ancestors of todays protists.

Cilia

________ (singular: ________) are short and numerous, and they move somewhat like oars on a boat.

Coral reefs

________ provide food and shelter to large numbers of fish and other organisms.

diploid

Many protists have complex sexual life cycles in which they alternate between a(n) ________ and a haploid phase, a process known as alternation of generations.

Waterborne protists

________ are found in streams, lakes, and oceans.

Parasitic protists

________ are responsible for some of the worlds deadliest diseases, including several kinds of debilitating intestinal diseases, African sleeping sickness, and malaria.

Flagella

________ (singular: flagellum) ________ are relatively long and few, are at the end of the organism and move from side to side.

Paramecium

________ can not survive without the macronucleus whereas it can not reproduce without the micronucleus.

Water molds

________ also reproduce sexually by undergoing meiosis and forming male (1N) and female structures.

Photosynthetic protists

________ play major roles in maintaining the health and well- being of many organisms and ecosystems.

Cilia

________ are evenly spaced and beat in a regular, efficient pattern.

Protists

________ are eukaryotes; not members of the plant, animal, or fungi kingdoms.

Water molds

________, or oomycetes, thrive on dead and decaying organic matter in water or as parasites of plants on land.

Water molds

________ grow into long branching filaments consisting of many cells formed by mitotic cell division.

Protists

________ are more complex than prokaryotes.

cilia

are short and numerous, and they move somewhat like oars on a boat

flagella

 flagella are relatively long and few, are at the end of the organism and move from side to side

types of symbiosis

mutualism (both species benefit), commensalism (one species benefits and the other is neither harmed nor helped), and parasitism (one species is helped by harming the other)
