Final Class Test

Question 1

Life cycles of bryophytes (mosses)

Answer 1

dom generation is the gameotyphyte phase

Question 2

Life cycles of pteridophytes (ferns), gymnosperms, angiosperms

Answer 2

dom=sporophyte phase

Question 3

Which stage are gameotophyte

Answer 3

haploid

Question 4

Which stage are sporophyte

Answer 4

diploid

Question 5

Where meiosis fits in with the stages of life cycles

Answer 5

meiosis produces spores in the moses and the ferns. meiosis produces sperm and eggs in gymnosperms and angiosperms.

Question 6

Where mitosis fit in with the stages

Answer 6

sprotophyte=mitosis stage when making cells

Question 7

alternation of generations

Answer 7

movement of gameotophyte to sporophyte and back

Question 8

gametophyte

Answer 8

the gamete producing part of the plant. haploid

Question 9

sporophyte

Answer 9

spore producing part of the plant. diploid

Question 10

gamete

Answer 10

sex cell

Question 11

archegonia

Answer 11

he fenale chambers where the gametes develop and where eggs are located

Question 12

antheridia

Answer 12

male chambers where the spent develops

Question 13

haploid

Answer 13

half the amount of chromosomes. n

Question 14

diploid

Answer 14

two sets of chromosomes. 2n

Question 15

spores

Answer 15

haploid cells. produced in sporophyte by meiosis

Question 16

sporophylls

Answer 16

modified leaf that bears sporangia (sporangia=reproductive organs)

Question 17

What are some differences between vascular plants and avascular plants?

Answer 17

vascular plants have vascular bundles with xylem and phloem. sporophyte is the dominant generation. some sperm have flagella
avascular plants. no xylem or phloem. cell to cell connection. gameotophyte is the dominant generation. all sperm have flagella

Question 18

Adaptations that allowed vertebrates to live on land.

Answer 18

lung development. some type of way to move on land. some sort of bony skeleton. scales or water resistant surface. internal fertilization

Question 19

If I gave you examples of organisms, be able to tell which ones are more closely related.

Answer 19

EX: bird, reptile, mammals. (birds and reptiles)
EX: angiosperm, gymnosperm, moss (angi and gymno)

Question 20

How mosses and flowering plants differ in their reproduction

Answer 20

mosses have flagellated sperm;therefore, they have to be in moist environments
flowering plants have double fertilization where one spent fertilizes the egg and the other one creates the endosperm.

Question 21

Types of symmetry and if given an organism that we have studied in lab or class, which body plan they have

Answer 21

Radial=central area and parts radiate out. EX: starfish, jellyfish
Bilateral=a front, a back, an anterior, a posterior. if cut one half looks like the other half. EX: humans
Asymmetry=no symmetry/not symmetrical. Amiba

Question 22

protostome

Answer 22

during division of cells it becomes divided but it is not perfectly symmetrical. digestive system opening when forming the coelom it forms cavities on either side. . anus on tip and mouth in bottom
mollusk anneluds. arthropods

Question 23

deuterostome

Answer 23

during division of cells it becomes divided perfectly. digestive system opening when forming the coelom it doesn’t form s cavity. it appears in the top. mouth in top and anus in bottom
echinoderms. chordates

Question 24

Know which parts of an organism are derived from:

Answer 24

Endoderm=when the cell divides it makes three layers. the endoderm is the innermost layer
Mesoderm=when the cell divides it makes three layers. the mesoderm is the middle layer
Ectoderm=outermost layer when the cell divides

Question 25

Bryophytes

Answer 25

mosses horne watts. liverworts. dom gen is gameotophyte (haploid). nonvascular

Question 26

Pteridophytes

Answer 26

ferns. dom gen is sporophyte. the spores they produce are haploid and grow into the gameotophyte. they use meiosis to make spores. mitosis make the frond that grows out of the ground

Question 27

Cnidarians

Answer 27

jellyfish. hydrozoas. nerve net that serves as their nervous system. have nematocysts that are the stinging cells. most are free floating. gelatinous type of body. very primitive animals

Question 28

Echinoderms

Answer 28

sea stars, sea urchins, sand dollars. tube feet that help them move. radial symmetry for them. sand dollars and sea urchins have a shell on the inside under the tube feet. eat and get rid of waste through the same hole.

Question 29

Annelids

Answer 29

segmented worms. first organisms to have tru celums. segmented. wash segment has its own kidneys/kidney area called protonephridia.

Question 30

Arthropods

Answer 30

insects and spiders. jointed appendages that allow them to walk. usually 2-3 body segments. insect=6 legs. spider=8 legs.
