Post Test

1
What stressor has had the largest impact on the morphology and life strategies of viridiplantae? (p. 582)
A)Avoidance of being eaten
B)Competing for sunlight
C)Dispersal of spores and seeds
D)Efficient water use
E)Becoming photosynthetic
2
True or false: The evolutionary trend in Viridiplantae is to reduce the size of the gametophyte and increase the size of the sporophyte. (p. 583)
A)True
B)False
3
In what way is Volvox an example of an organism with primitive traits (like Chlamydomonas) that yet demonstrates some structural advances similar to Viridiplantae? (p. 585)
A)They show cellular specialization: some cells give up their ability to reproduce.
B)The shape of Volvox is a hollow ball, which suggests the development of a broader, three-dimensional body shape seen in higher plants.
C)Volvox is capable of living on land.
D)Cells on the exterior of a Volvox colony have flagella.
E)They have gametes, unlike unicellular Chlamydomonas.
4
What feature of cell walls in the charophytes allows cytoplasmic continuity between adjacent cells? (p. 586)
A)Gap junctions
B)Tight junctions
C)Stomata
D)Plasmodesmata
E)Desmosomes
5
Which stage is the most dominant in the bryophyte life cycle? (p. 587)
A)Antheridium
B)Archegonium
C)Sporophyte
D)Gametophyte
E)Spores
6
True or false: The evolutionary trend seen in the bryophytes where by the gametophyte is dominant in the life cycle has been enhanced and emphasized in the higher plants. (p. 589)
A)True
B)False
7
True or false: Club mosses can grow taller than true mosses due to vascular refinements in their stems. (p. 590)
A)True
B)False
8
What do whisk ferns, horsetails, and ferns have in common? (p. 591)
A)All have vascular tissues.
B)All have very small seeds.
C)All have fibrous root systems.
D)All of them cluster their sporangia together as sori.
E)All of the above statements represent commonalities.
9
The extinct "bridging" group of plants which connected seedless vascular plants from those with seeds were the (p. 593)
A)whisk ferns.
B)horsetails.
C)ferns.
D)progymnosperms.
E)tree ferns.
10
What is the name of the break in the integuments surrounding the megasporangium which allows entry of sperm for fertilization? (p. 594)
A)The nucellus
B)The access channel
C)The micropyle
D)The foramen
E)Canalicula
11
Where does a fruit come from? (p. 598)
A)The seed integuments
B)Specialized tissues of the zygote
C)Specialized tissues of the megaspore
D)It's derived from the ovary wall.
E)Petals which fold backwards around the ovary, then fuse and thicken
