Question 7

a multicellular diploid organism that produces spores by meiosis - spores germinate and grow into gametophytes

Answer 7

Sporophyte -

Question 8

a multicellular haploid organism that produces gametes by mitosis can be either male or female, females produce eggs, males produce sperms,

Answer 8

Gametophyte -

Question 9

fusion of gametes produces a _____ that grow into a multicellular sporophyte

Answer 9

zygote

Question 10

the sperm producing organ of a gametophyte

Answer 10

Antheridium -

Question 11

the egg producing organ of a gametophyte

Answer 11

Archegonium -

Question 12

spores (produced by meiosis) are indistinguishable in size and may give rise to either male or female gametophytes

Answer 12

Homosporous -

Question 13

spores differ in size
megaspores produce megagametophytes, which produce eggs
microspores produce microgametophytes, which produce sperms

Answer 13

Heterosporous -
