Which feature best distinguishes protists from other eukaryotes?
Which feature best distinguishes protists from other eukaryotes? They cannot be categorized into a single kingdom.
Which of the following describes the similarity between Diplomonads and parabasalids the best?
Which of the following describes the similarity between Diplomonads and parabasalids the best? They have modified mitochondria and multiple flagella.
What characteristics do Diplomonads and parabasalids have in common?
They have one nucleus instead of two. They have mitochondria. The have membrane-bound organelles. All of these characterize both parabasalids and diplomonads.
Which of the following are important features of eukaryotes that distinguish them from prokaryotes?
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell’s genetic material, while prokaryotic cells don’t have a nucleus and have free-floating genetic material instead.
What characteristics are unique to protists?
Characteristics of Protists
- They are eukaryotic, which means they have a nucleus.
- Most have mitochondria.
- They can be parasites.
- They all prefer aquatic or moist environments.
What is unique about protists?
Protists vary greatly in organization. While many protists are capable of motility, primarily by means of flagella, cilia, or pseudopodia, others may be nonmotile for most or part of the life cycle. …
How might someone distinguish between Diplomonads and Parabasalids?
Diplomonads are defined by the presence of a nonfunctional, mitochrondrial-remnant organelle called a mitosome. Parabasalids are characterized by a semi-functional mitochondria referred to as a hydrogenosome; they are comprised of parasitic protists, such as Trichomonas vaginalis.
Are Diplomonads heterotrophic or autotrophic?
Diplomonads are bi-flagellated heterotrophic protists that lack mitochondria and golgi. They are thought by some to be relatively primitive, but may lack these features because they live in anaerobic environments (e.g., Giardia).
In what ways do diplomonads and parabasalids differ from each other?
Why do some biologists describe the mitochondria of diplomonads and parabasalids as highly reduced?
Why do some biologists describe the mitochondria of diplomonads and parabasalids as “highly reduced”? Since the unknown protist is more closely related to diplomonads than to euglenids, it must have originated after the diplo- monads and parabasalids diverged from the euglenozoans. the diplomonad.
Which characteristic is unique to prokaryotic cells?
Prokaryotic cells differ from eukaryotic cells in that their genetic material is contained in a nucleoid rather than a membrane-bound nucleus. In addition, prokaryotic cells generally lack membrane-bound organelles.
Which is a true difference between prokaryotes and eukaryotes?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
