Flashcards in Test 3 Deck (36):
1

Apicomplexans

use a complex of organelles at tip of cell to invade host tissues

2

Brown algae

multicellular marine autotrophs

3

Ciliates

covered in cilia

4

Diatoms

unicellular with silica in cell walls

5

Loboseans

locomotion by pseudopods

6

What group of protists was formerly classified as fungi, considering their method of getting nutrition and cell wall construction?

oomycetes

7

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

8

What is a shared derived character of Amoeba and the slime molds?

motility of pseudopods

9

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

10

T or F: All the groups of modern land plants are characterized by having embryos protected by tissues of parent plants.

True

11

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

12

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

13

In the alteration of generations life cycle, at what point does the gametophyte change from haploid to diploid?

during fertilization

14

Angiosperms

production of flowers

15

Conifers

needle-like leaves with thick cuticles

16

Ferns

vast forests of these plants in the Carboniferous period are the source of today's fossil fuels

17

Hornworts

nonvascular, seedless plants

18

Mosses

nonvascular, seedless plants

19

There are several adaptations of angiosperms that have contributed to their evolutionary success, including:

co-evolution with animal pollinators

20

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.

21

T or F: Unicellular fungi are called yeast.

True

22

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.

23

Why are fungi excellent decomposers in the environment?

Fungi can produce unique digestive enzymes.

24

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

25

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

26

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.

27

Penicillium

some species were used in the production of an antibiotic

28

Saccharomyces

Anheuser-Busch has its own species for the production of the Budweiser beer

29

Smut

pathogen of some plant species, such as corn

30

Truffles

harvesters of this delicacy usually use pigs to search for them

31

T or F: Animals typically do not have tight junctions between adjacent cells.

False

32

In the earliest tetrapods, lungs provided a supplemental gas exchange surface. Lungs evolved from the ..?.. of fishes.

swim bladders

33

Amphibians are terrestrial animals that are still dependent n watery habitats for:

reproduction

34

T or F: Reptiles lay amniotic eggs.

True

35

Feathers are a uniquely derived character for birds. Feathers are modified:

scales

36

Besides having mammary glands, another feature common to all mammals is:

hair
