Bio 200 Lecture 13 Exam Questions
and Answers
Protist Cell Surfaces - ANSWER-extra cellular material can be excreted around the
cell, with the point of protecting the protists from negative aspects of the
environment.
Protist Nutrition - ANSWER-autotrophic and heterotrophic. Some are photosynthetic
due to primary endosymbiosis, others due to secondary endosymbiosis.
Protist Reproduction - ANSWER-asexual and sexual
The Development of Multicellularity - ANSWER-eukaryotic cells begin to live in close
association, association becomes colonies, individuals in colony take on different
roles, colony begins to function as an individual.
Protist Groups - ANSWER-Alveolates, Stramenopiles, Rhizarians, excavates,
ameobozoans, choanoflagellates.
Alveolates - ANSWER-Dinoflagelattes, Apicomplexa, ciliates
Dinoflagelattes - ANSWER-photosynthetic and have 2 flagella with in 2 grooves on
their surfaces. Luminous, marine and often have plate-like armor. Important
endosymbionts b/c they live in corals and help with their photosynthetic properties.
Example= Gymnopodium which cause red tides (toxins that kill)
Apicomplexa - ANSWER-parasites with apical complex (allows them to invade).
Examples= Plasmodium Falciparum which causes malaria.
Ciliates - ANSWER-heterotrophic, unicellular, but they vary greatly in size. Move
using cilia. Example= paramecium.
Stramenopiles - ANSWER-Brown algae, Diatoms, Oomycetes.
Brown Algaes - ANSWER-multi-cellular, can be quite large. Example=Giant kelp
which give food and shelter to sea otters.
Diatoms - ANSWER-often photosynthetic, excrete protective silica, shells. Use
sexual and asexual reproduction. Have flagella only on male gametes. In all oceans.
Oomycetes - ANSWER-(water molds and downy mildews) are not actually molds
and use external digestion. Can't move, filamentous. Example= white rust, a plant
pathogen
