Q

Why is the bottom of a leaf typically a lighter shade of green than the top of the leaf?

A

The spongy mesophyll is typically on the underside of the leaf, and it is usually a lighter shade of green due to the fact that the photosynthesis cells are not tightly packed there.

Q

What kind of vascular tissue makes up most of the wood in a woody stem? What kind of vascular tissue is found in the inner bark of a woody stem?

A

xylem make up most of the wood in a woody stem, while phloem are found in the inner bark

16
Q

What is the dominant generation in the moss life cycle? Is it haploid or diploid?

A

gametophyte generation; haploid

17
Q

A fern has antheridia and archegonia. Which part of the fern life cycle is it in? Is this the dominant generatin?

A

gametophyte generation; not dominant for ferns

18
Q

Why are plants from phylum Bryophyta relatively small?

A

Since plants from phylum Bryophyta have no vascular tissue, there is no efficient way to transport nutrients throughout the plant.

19
Q

If a 15-foot tall plant has a root system that goes four feet deep, is it a fibrous or taproot system?

A

fibrous

20
Q

What are the male and female reproductive organs in a tree from phylum Coniferophyta?

A

female is the seed cone; male is pollen cone

21
Q

What is the fundamental difference between monocots and dicots?

A

the number of cotyledons produced in the seed

22
Q

Name another difference between monocots and dicots.

A

in monocots the venation is parallel, while it is netted in dicots; the fibrovascular bundles are packaged differently in monocots and dicots; typically, monocots have fibrous root systems whereas dicots have taproot systems; finally, monocots usually produce flowers in groups of three or six while dicots produce flowers in groups of four or five (only need to list one)

23
Q

A plant produces seed cones and pollen cones. Is it vascular? To what phylum (of the ones that we discussed) does it belong?

A

Coniferophyta

24
Q

A plant produces flowers. To what phylum does it belong?

A

Anthophyta
