Unit 2: Plants/Fungi (ch 22, 23)

Question 1

What are three examples of bryophytes?

Answer 1

Liverworts, mosses, and hornworts

Question 2

What are three examples of seedless vascular plants?

Answer 2

Club/spike mosses, whisk ferns, and horsetails.

Question 3

What are three examples of gymnosperms?

Answer 3

Gnetophytes, ginkgos, and conifers

Question 4

What are the two major groups of angiosperms?

Answer 4

Monocots and eudicots

Question 5

What generation is dominant for bryophytes?

Answer 5

The gametophyte is longer-lived and larger.

Question 6

What is the function of the cuticle and stomata?

Answer 6

The cuticle helps reduce evaporative water loss, and the Stomata are closeable pores that allow gases (CO2 and oxygen) in and out or close off to conserve water.

Question 7

What are two types of plant vascular tissue?

Answer 7

Xylem and Phloem

Question 8

What do microspores and megaspores produce?

Answer 8

Microspores produce sperm-making gametophytes (pollen grains), and megaspores develop egg-producing gametophytes.

Question 9

Where does reproduction occur in a plant?

Answer 9

A flower is specialized for reproduction, the male half consisting of the stamen (which contains filament and anther) and the female portion (containing the stigma, style, and ovary).

Question 10

What are the male and female structures for a plant?

Answer 10

The male structures are in the stamen, and the female structures are in the carpel.

Question 11

What two parts make up the stamen? What three parts make up the carpel?

Answer 11

The filament and the anther are the two parts that make up the stamen, and the three parts that make up the Carpel are the stigma, style, and ovary.

Question 12

What is the chromosome number for the endosperm?

Answer 12

The endo sperm is a Triploid (3n)

Question 13

How do fungi obtain nutrition?

Answer 13

They are heterotrophs that obtain nutrition from their environment via extracellular digestion.

Question 14

What are the individual filaments of fungi? What is the mesh of branching filaments for fungi?

Answer 14

The individual filaments of fungi are called hypha, and the mesh of branching filaments is called mycelium.

Question 15

Is the dikaryotic stage for fungi sexual or asexual?

Answer 15

The Dikaryotic stage for fungi is sexual.

Question 16

What are the five major groups of fungi?

Answer 16

The five major groups of fungi are Chytrids, Zygote fungi, Glomeromycetes, sac fungi, and club fungi.

Question 17

Which fungi group have flagella?

Answer 17

The Chytrids are the only modern fungi to have flagellated spores.

Question 18

What is mycosis?

Answer 18

A disease caused by a fungus.

Question 19

What type of sexual spores are produced by zygote fungi?

Answer 19

Zygote fungi produce diploid spores known as zygospores.

Question 20

What are two examples of zygote fungi?

Answer 20

Two examples of zygote fungi are Rhizopus species (like black bread mold) and Pilobolus.

Question 21

What is mycorrhizae?

Answer 21

A mutually beneficial partnership between a fungus and a plant root.

Question 22

Which group of fungi is the most diverse?

Answer 22

Ascomycota (commonly known as Sac fungi) are the most diverse group of fungi.

Question 23

What type of spores are produced by sac fungi?

Answer 23

Ascospores are the type of spores that sac fungi produce.

Question 24

What are two examples of sac fungi?

Answer 24

Two examples of sac fungi are cup fungi and Conidia.

Question 25

What type of spores are produced by club fungi?

Answer 25

The spores produced by club fungi are basidiospores.

Question 26

What are the two components of a lichen?

Answer 26

Two components of a lichen are a fungus and an alga or some photosynthetic partner.

Question 27

What are two examples of plant pathogens?

Answer 27

Two examples of fungal plant pathogens are wheat stem rust and powdery mildew.

Question 28

What are two examples of human pathogens?

Answer 28

Two examples of fungal human pathogens are ringworm and vaginal yeast (candida).
