These micrographs show one single-celled eukaryote, a tubulinid amoeba, engulfing another, a ciliate. Describe a key feature of eukaryotes suggested by these images, and summarize the role of endosymbiosis in the evolutionary history of the eukaryotes. Are tubulinid amoebas more closely related to all other protists than they are to plants,

Multicellular algae (top row A-C, left to right) and
unicellular algae (D-F):
A. Brown kelp (seaweed) Macrocystis
B. Red algae Corallina
C. Green algae Halimeda incrassata
D. Bioluminescence (blue color) from dinoflagellates
(flagellated unicellular algae).
E. Diatoms (shelled unicellular algae)
F. Colonial green algae Volvox (bottom row)
Give an example of a protist that is:(a) a parasite of humans(b) very large and photosynthetic(c) a unicellular species with two flagella and photosynthetic(d) covered in cilia
Jr. Scientist discovers a never-before-classified protist. It contains multinucleated filaments, similar to fungal hyphae however, upon closer examination the cell walls are found to be
composed of cellulose rather than chitin. They do not perform photosynthesis but instead acquire nutrients by way of parasitism or decomposition. Jr. Scientist has likely discovered
a rhizarian
a foraminiferan
an oomycete
a mycetozoan

- I don't understand this practice bio question: Despite the fact that modern taxonomists have abandoned the Kingdom Protista, the term "protist" persists in the biological literature. Explain the current meaning of the term protist and give several specific examples.arrow_forwardProtists are(a) single-celled eukaryotes.(b) multicellular eukaryotes.(c) single-celled prokaryotes.(d) single-celled akaryote. Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.arrow_forwardPlease help to answer and also provide a step-by-step explanation: Movement is a type of response to stimuli. Many unicellular organisms can move in response to chemical changes outside the cell – amoeba exhibits locomotion, paramecium use cilia to get around. Protists such as the Amoeba and the Paramecium are important to our discussion of evolution because of their ability to respond to changes in the environment. These single-celled eukaryotes have this ability because a) their DNA responds to stimuli from the environment, b) they have the same germ cell layers that the Cnidaria have, c) new proteins, located in the cell membrane, have shapes and charge patterns that react to a stimulus by generating an electrical impulse. d) they have a Golgi Apparatus that measures the stimulus from the environment, e) none of these are possible.arrow_forward
