(a) they are unicellular, colonial, coenocytic, or simple multicellular organisms (b) their cilia and flagella have a 9 + 2 arrangement of microtubules (c) they are prokaryotic, as bacteria and archaea are (d) some are free-living, and some are endosymbionts (e) most are aquatic and live in the ocean or in freshwater pondsarrow_forwardUsing either bacteria or protists as an example, how can bacteria or protists reproduce sexually (i.e., exchange genetic material)?

Their modes of reproduction are extremely diverse. They do not all possess the same mitochondria structure. They did not all evolve from a shared common ancestor. Their DNA sequence is not identical. They fulfill many different ecological roles. They are found in a variety of habitats.arrow_forward
- After plasmogamy has occurred, many molds (Mucoromycetes) exist in a heterokaryotic stage for up to centuries at a time. What occurs at the immediate end of this stage? The nuclei fuse in a process called karyogamy. The hyphae fuse in a process called karyogamy. Diploid spores are produced in various spore-producing structures. A haploid zygote is formed that becomes multicellular through repeated rounds of mitosis.arrow_forwardWhy is 'protists' considered a polyphyletic grouping?
