Archae represent a kingdom of bacteria which live in extreme environments. Archae bacteria are prokaryotic cells, meaning they do not have a membrane bound nucleus nor membrane bound organelles. Prokaryotes have ribosomes and circular DNA. They may have smaller rings of DNA called plasmids. Protists represent a eukaryotic kingdom. Eukaryotic cells have a membrane bound nucleus and membrane bound organelles. The DNA is not free floating, it is enclosed in the nucleus and arranged in chromosomes. Archae cells are much smaller than protist cells. Protist cells can be found as unicellular organisms,, living in colonies or multicellular. Archea are unicellular and may b e in clumps or chains.

Answer:

c. Spindle fibers

Explanation:

In eukaryotic cells, the centrioles are small sets of microtubules composed of tubulin proteins. Moreover, in animal cells, a centrosome is an organelle localized near the nucleus which contains a pair of centrioles. These organelles (centrosomes) are referred to as microtubule-organizing centers. During Anaphase, centrioles move to opposite sides in the cell in order to organize the spindle fibers and separate the chromosomes during cell division.
