Q

Chlamydomonas Sexual Lifecycle

A

Zoospores (haploid cells) have different mating strains (+ or -): isogametes
Zoospore nuclei fuse (syngamy): sexual reproduction
Zygote is resistant to environmental stressors
Meiosis produces more zoospores

Q

Oedogonium Sexual Lifecycle

A

Antheridium (male part) releases antherozoids
Antherozoids travel to Oogonium (female part)-fuse with egg
Oospore (diploid) undergoes meiosis to form zoospore (haploid)
Zoospore forms into a filament
Mitosis occurs by fragmentation

Q

Liverwort Sexual Lifecycle

A

Sperm is released from antheridium- travels to archegonium

Q

Fern Sexual Lifecycle

A

Sporangium produce spores (haploid)
Spores develop into gametophytes
Underside of gametophyte contains archegonium and antheridium
Sperm is released from antheridium and travels to archegonium
Fertilization of egg produces zygote
Zygote develops into sporophyte (leaf)
Sporangium are located on underside of leaf
