final lab

Question 1

distinguishing characteristic of fungi

Answer 1

no chlorophyll, heterotrophic, mycellium

Question 2

rhizopus morphology

Answer 2

adult looks like a lollipop

Question 3

rhizopus life cycle

Answer 3

sexual. Sporangium produces haploid spores that fall onto a food source and germinate into haploid filaments. Haploid hyphae fuse to form a diploid zygospore. zygospore undergoes meiosis

Question 4

defining characteristic of ascomycetes

Answer 4

sexual spores are produced in saclike asci

Question 5

ascomycota sexual life cycle

Answer 5

Haploid mycelia fuse to form a dikaryotic hyphae. Hyphae produce asci that form a fruiting body ascocarp.

Question 6

ascomycota asexual life cycle

Answer 6

ascocarp relases ascospores that germinate into haploid conidiophore filaments. Conidiophores produce conidia which germinate into mycelia.

Question 7

Basidiomycota: Mushrooms

Answer 7

produce spores called basidia which are released from gills. Spores germinate into haploid mycelia. Mycelia fuse but nuclei do not. Forms a dikaryotic mycelium that divides by meiosis to form a mushroom.

Question 8

what are lichens composed of

Answer 8

fungus and green algae or cyanobacteria

Question 9

saphrophytic

Answer 9

obtain food from decomposition and absorption of nutrients from dead organic matter

Question 10

mycorrhizae

Answer 10

symbiotic relationship between mycelium and plant roots. mycelium directly supplies nutrients to plant roots in exchange for food.

Question 11

ascomycota spores (ascospores)

Answer 11

look like hands with skinny fingers

Question 12

basidiomycota spores (basidia)

Answer 12

club shaped

Question 13

distinguishing characteristics of the animal kingdom

Answer 13

multicellular, heterotrophic

Question 14

coelom

Answer 14

body cavity which is the space between the body wall and digestive tract. fully lined with mesoderm

Question 15

pseudocoelom

Answer 15

partly lined by endoderm, partly lined by mesoderm

Question 16

porifera characteristics

Answer 16

no tissues, symmetry, or coelom. collar cells for feeding.

Question 17

osculum

Answer 17

pushes water out of sponges for feeding

Question 18

cnidaria

Answer 18

2 tissue layers, radial symmetry, gastrovascular cavity, cnidocytes

Question 19

platyhelminthes

Answer 19

triploblastic, acoelomate, bilateral symmetry

Question 20

auricles

Answer 20

ear like bulges on the side of planarians head

Question 21

blastophore

Answer 21

opening that develops into either mouth or anus

Question 22

cnidarian life cycle

Answer 22

polyp, medusa

Question 23

ephyra

Answer 23

juvenile jellyfish

Question 24

nematocyst

Answer 24

discharge a thread when cnidocyte is touched

Question 25

spicules porifera

Answer 25

give strength to sponge body

Question 26

tentacles cnidaria

Answer 26

used to capture and eat prey

Question 27

rhizopus spore

Answer 27

dark spiky zygospore, look like sperm

Question 28

dorsal

Answer 28

top/ back side

Question 29

ventral

Answer 29

bottom/front side

Question 30

cephalization

Answer 30

concentration of a nervous system in the head

Question 31

nematoda (ascaris)

Answer 31

unsegmented roundworm, pseudocoelom, cuticle

Question 32

mollusca

Answer 32

coelom, foot, visceral mass, mantle

Question 33

annelida

Answer 33

segmented worm, closed circulatory system

Question 34

arthropoda

Answer 34

segmented exoskeleton, jointed limbs, open circulatory system

Question 35

echinodermata

Answer 35

bilateral symmetry larva, radial symmetry adults, no excretory system, no cephalization, water vascular system

Question 36

chordata

Answer 36

notochord, hollow dorsal nerve chord, post anal tail, gill slits

Question 37
