Exam 18: Protista, Plantae, and Fungi

Most of the cells of a multicellular eukaryote are genetically identical yet may eventually become specialized for specific tasks;how can these differences in cell function be explained?

Despite some similarities in appearance and habitat selection,biologists consider the fungi more closely related to animals than plants;for example,both groups ________,a feature completely absent in plants.

Despite their classification as protists,the evolutionary tree suggests that amoebas and the green algae are more closely related to animals and plants,respectively,than one another.

The kingdom Protista is quite diverse and the relationship among its various members is unclear.The best method of clarifying those relationships will require that biologists

Without angiosperms,bryophyte reproduction would almost entirely cease.

The cuticle predisposed plants for a terrestrial existence by improving water retention.

Examine the following evolutionary tree. One prediction based on the arrangement of protists in the illustration is that the DNA of the

The most ancient eukaryotic fossils are similar to red algae,a type of ________abundant today.

Sexual reproduction can be observed in all the Eukarya kingdoms,although not in all Eukarya species.

Gymnosperms and angiosperms are believed to be more closely related to one another than the other major plant groups because

Note the location of the air bladders in the following illustration of the kelp;how might these structures represent an adaptive advantage?

The main body of a multicellular fungus is known as the

The tendency toward sexual reproduction in the more complex eukaryotes suggests a greater number of benefits than asexual reproduction;one potential benefit could be

In comparison to eukaryotes,prokaryotes are smaller but have a higher surface area to volume ratio;why might this be advantageous?

Most plants produce flowers,which greatly improve the probability of ________.

The arrival of a pollen grain on the carpel of a flower or the scale of a female cone is termed

Although seeming quite distinct,cotton,morphine,and flour are all obtained from flowering plants,otherwise known as ________.

Some plants rely on nocturnal bats for pollination rather than insects;in what way might these plants differ from those pollinated by insects?

The majority of protists are motile,enabling heterotrophic species to locate organic resources and autotrophic species to orient to sunlight.

What criteria best characterize membership in the kingdom Protista?
