Lab Exam #1

Question 1

Plants are in Domain ___ and Kingdom ___.

Answer 1

Eukarya; Plantae

Question 2

Plants alternate between the gametophyte and sporophyte generations. The gametophyte generation is haploid/diploid and produces gametes/spores while the sporophyte generation is haploid/diploid and produces gametes/spores.

Answer 2

haploid, gametes; diploid, spores

Question 3

The cell wall of a plant is composed of what carbohydrate?

Answer 3

Cellulose

Question 4

In what form of carbohydrate does a plant store its food?

Answer 4

Starch

Question 5

What are the two types of vascular tissue, what does each transport, and in what direction?

Answer 5

Xylem transports water and minerals upwards. Phloem transports sugar in both directions.

Question 6

How odes pollination of gymnosperms differ from pollination of most angiosperms that have brightly colored flowers?

Answer 6

The pollination of gymnosperms is reliant on the wind to transport pollen. Angiosperms with bright flowers can attract pollinators to transport pollen.

Answer 23

b. Herbaceous eudicots

Question 24

Which group(s) of plants has/have a vascular cylinder (stele) surrounded by an endodermis and Casparian strip in the roots?

a. Monocots
b. Herbaceous eudicots
c. Woody eudicots
d. All of the above

Answer 24

d. All of the above

Question 25

Which group(s) of plants has/have parallel leaf venation?

a. Monocots
b. Eudicots
c. Both Monocots and Eudicots

Answer 25

a. Monocots

Question 26

Which of the following is not present in/on a plant seed?

a. Food for embryo
b. Protective seed coat
c. Young embryonic gametophyte
d. Young embryonic sporophyte

Answer 26

c. Young embryonic gametophyte

Question 27

What does the periderm do?

Answer 27

It replaces the epidermis and cortex with secondary growth.

Question 28

Why is the endodermis necessary for the roots, but not the stem of the plants?

Answer 28

The endodermis determines what the plant allows to access the vascular tissue system. It is not essential in the stem because stems do not absorb anything.
