Test 3 Flashcards
Apicomplexans
use a complex of organelles at tip of cell to invade host tissues
Brown algae
multicellular marine autotrophs
Ciliates
covered in cilia
Diatoms
unicellular with silica in cell walls
Loboseans
locomotion by pseudopods
What group of protists was formerly classified as fungi, considering their method of getting nutrition and cell wall construction?
oomycetes
In the past, Pfiesteria piscicida has been responsible for massive fish kills along the coast of North Carolina. This species is a dinoflagellate. Like all dinoflagellates, Pfiesteria:
has to flagella per cell
What is a shared derived character of Amoeba and the slime molds?
motility of pseudopods
Glaucophytes are modern-day plants that are probably the most similar to the common ancestor of all plant groups. What is a unique character present in the glaucophytes that is not present in other plants?
peptidoglycan in the chloroplasts
T or F: All the groups of modern land plants are characterized by having embryos protected by tissues of parent plants.
True
What is an adaptation of terrestrial plants the permits the movement of food and water through the body o the plant.?
phloem and xylem in all three plant organs
In the alternation of generations life cycle, what is the starting point in the life cycle?
- you must have these to begin at all*
gametophytes
In the alteration of generations life cycle, at what point does the gametophyte change from haploid to diploid?
during fertilization
Angiosperms
production of flowers
Conifers
needle-like leaves with thick cuticles
Ferns
vast forests of these plants in the Carboniferous period are the source of today’s fossil fuels
Hornworts
nonvascular, seedless plants
Mosses
nonvascular, seedless plants
There are several adaptations of angiosperms that have contributed to their evolutionary success, including:
co-evolution with animal pollinators
One of the synapomorphies that characterize fungi is absorptive heterotrophy, which means that the organism must first….?…, then it must …?…
send digestive enzymes outside the organisms body to break down its food, then it takes in the smaller, digested monomers through the body.
T or F: Unicellular fungi are called yeast.
True
Which the following statements inaccurate about fungal mycelia?
(i) Fungal hyphae make up fungal mycelia
(ii) Mycelia are almost always composed of diploid cells.
(iii) Mycelia are generally found underneath a substrate.
(iv) They are generally found in moist habitats.
(v) They can extend over great distances with a large suface area.
(ii) Mycelia are almost always composed of diploid cells, is an inaccurate statement about fungal mycelia.
Why are fungi excellent decomposers in the environment?
Fungi can produce unique digestive enzymes.
In some stages of a fungal life cycle, there are dikaryotic cells; that means that the cells have ..?.. inside them during those stages of the life cycle.
two un-fused haploid nuclei
The Zygomycota (of which the black bread mold Rhizopus is an example) are characterized by a zygospore stage and a sporangiophore stage in the life cycle. What is the importance of the zygospore stage?
It is the only diploid cell in the life cycle
The evolutionary success of angiosperm can be partially attributed to their mutualistic relationship with the Glomeromycota, a group of organisms made up exclusively of mycorrhizae fungi. What is the nature of the mycorrhizae relationship.?
The plants provide the fungi with photosynthetic products, while the fungi increases the absorptive surface area of the plants’ roots.
Penicillium
some species were used in the production of an antibiotic
Saccharomyces
Anheuser-Busch has its own species for the production of the Budweiser beer
Smut
pathogen of some plant species, such as corn
Truffles
harvesters of this delicacy usually use pigs to search for them
T or F: Animals typically do not have tight junctions between adjacent cells.
False
In the earliest tetrapods, lungs provided a supplemental gas exchange surface. Lungs evolved from the ..?.. of fishes.
swim bladders
Amphibians are terrestrial animals that are still dependent n watery habitats for:
reproduction
T or F: Reptiles lay amniotic eggs.
True
Feathers are a uniquely derived character for birds. Feathers are modified:
scales
Besides having mammary glands, another feature common to all mammals is:
hair
