bioL quiz 5

Question 1

ascocarp

Answer 1

mature fruiting body produced by hyphae

Question 2

ascus

Answer 2

sexual spore bearing cells in ascomyta

Question 3

basidium

Answer 3

club shaped spore bearing structures

Question 4

conidia

Answer 4

asexual spores produced by fungi

Question 5

conidiophore

Answer 5

produce conidia

Question 6

dikaryotic

Answer 6

2 haploid nuclei

Question 7

hyphae

Answer 7

branch like filaments that make up mycelium

Question 8

lichen

Answer 8

symbiotic relationship between a fungus and cyanobacterium

Question 9

mycelium

Answer 9

root like structure made up of interwoven hyphae

Question 10

mycorrhizae

Answer 10

symbiotic relationship between plant and fungus root systems where fungus decomposes organic material in soil and supplies minerals directly to plant in exchange for sugar and amino acids

Question 11

parasitic form

Answer 11

extract nutrients from living plants or animals

Question 12

saprophytic form

Answer 12

extract nutrients from dead decomposing organic matter

Question 13

sporangium

Answer 13

produces asexual haploid spores

Question 14

zygospore

Answer 14

spiky diploid structure with thick dark walls. resistant to harsh environments

Question 15

how does rhizopus reproduce sexually

Answer 15

sporangium produces haploid spores which fall onto a food source and germinate into haploid filaments

Question 16

how do ascomycetes reproduce

Answer 16

sexually when haploid mycelia fuse to form a dikaryotic hyphae

Question 17

radial symmetry

Answer 17

symmetry at multiple points ex: starfish

Question 18

why are sponges the most primitive animal

Answer 18

they have a simple body plan and lack symmetry and true tissues. also no coelomic plan.

Question 19

how do sponges obtain food

Answer 19

nutrients in water are trapped in sticky mucus at the base of a flagellum of a collared cell. they’re digested into collar cell vacuoles and passed to other cells.

Question 20

3 advances cnidarians have over sponges

Answer 20

distinct tissues, radial symmetry, 2 tissue layers
