Letter: Shape: Margin: Venation:

a. Deltoid Entire Parallel
b. Elliptical Serrate Pinnate
c. Lobed Entire Pinnate
d. Cleft Dentate Palmate

Question 4

In a leaf, what is the function of the following tissues:

a. palisade mesophyll
b. spongy mesophyll
c. epidermis
d. xylem
e. phloem
f. chollenchyma

Answer 4

a. photosynthesis
b. photosynthesis
c. protection
d. transports water & minerals
e. transports food & organic substances
f. support

Question 5

What controls the opening and closing of the stomata on a leaf?

Answer 5

The guard cells control the opening and closing of the stomata.

Question 6

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

Answer 6

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.

Question 7

Name two types of pigments that cause leaves to be a color other than green.

Answer 7

Carotenoids & anthocyanins

Question 8

If a tree has no abscission layer, will it be deciduous?

Answer 8

no

Question 9

Where is the abscission layer?

Answer 9

between the stem and the petiole

Question 10

Name the four regions of a root. Which region contains undifferentiated cells?

Answer 10

root cap, meristematic region, elongation region, maturation region; undifferentiated cells are in the meristematic region

Question 11

See page 462, question #13

Answer 11

a. dicot

b. monocot

Question 12

What allows woody stems to have no limits to their growth, unlike herbaceous stems?

Answer 12

the cork cambium can always produce more bark

Question 13

What is the function of vascular cambium?

Answer 13

produces new vascular tissue

Question 14

If a stem has cork cambium, is it woody or herbaceous?

Answer 14

woody

Question 15

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?

Answer 15

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

Question 16

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

Answer 16

gametophyte generation; haploid

Question 17

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

Answer 17

gametophyte generation; not dominant for ferns

Question 18

Why are plants from phylum Bryophyta relatively small?

Answer 18

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

Question 19

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

Answer 19

fibrous

Question 20

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

Answer 20

female is the seed cone; male is pollen cone

Question 21

What is the fundamental difference between monocots and dicots?

Answer 21

the number of cotyledons produced in the seed

Question 22

Name another difference between monocots and dicots.

Answer 22

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)

Question 23

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

Answer 23

Coniferophyta

Question 24

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

Answer 24

Anthophyta

Question 25

What do we call the structure that attaches that blade of the leaf to the stem?

Answer 25

the petiole
