Which life cycle is the animal life cycle?
Which life cycle is the life cycle of green algae?
Gametic, Zygotic, and Sporic?
Is the diploid phase of the gametic life cycle unicellular or multicellular?
In the gametic life cycle, describe the gametangia:
-What phase are they (haploid/diploid)
-What do they give rise to?
-Are those cells haploid or diploid?
--gametangia give rise to gametocytes/germ cells
--gametocytes/germ cells are 2N
In the gametic life cycle, gametocytes give rise to gametes by what process? What is the ploidy level of the gametes?
Is the haploid phase of the gametic life cycle unicellular or multicellular?
What happens during the haploid phase of the gametic life cycle?
unicellular, 1N gametes will fuse in a process called syngamy to create a 2N zygote that will then undergo mitosis.
What is it called when gametes fuse to produce a zygote?
What organisms have a zygotic life cycle?
fungus and green algae
How are the gametes derived in the zygotic life cycle?
haploid gametocytes give rise to haploid gametes by mitosis
Is the haploid phase of the zygotic life cycle (unicellular/multicellular)?
Is the diploid phase of the zygotic life cycle (unicellular/multicellular)?
How do gametes become spores?
gametes undergo syngamy. The zygote is diploid and unicellular. This 2N zygote divides by meiosis to produce 1N spores.
True or False: In the zygotic life cycle, the germ cycle is the gametocyte.
False. The germ cell is the zygote. It can't be the gametocyte because the gametocyte in the zygotic life cycle divides by mitosis. It's the zygote because it divides by meiosis to create spores.
Which two life cycles are inverse of each other?
Gametic and zygotic
What organisms participate in the sporic life cycle?
green algae and ALL embryophytes
Which life cycle has a haploid and diploid phase that is BOTH multicellular?
Sporic Life Cycle
What happens in the diploid phase of the sporic life cycle?
Sporophyte sporangia contain 2N sporacytes that undergo meiosis to produce 1N spores
What is the germ cell in the sporic life cycle?
Sporacytes because they undergo meiosis to produce haploid spores
What phase (haploid/diploid) begins with the embryophyte seed?
What happens during the sporic life cycle?
gametophyte gametangia contain 1N gametocytes that undergo mitosis giving rise to gametes. Gametes undergo syngamy giving rise to a 2N zygote
In the sporic life cycle, the zygote divides by what process (meiosis/mitosis)? What is the zygote ploidy level?
mitosis; 2N zygote
In the zygotic life cycle, the zygote divides by what process (meiosis/mitosis)? Giving rise to what cells? What is the new cells ploidy level?
meiosis; giving rise to 1N spores
What is an example of an organism with an isomorphic sporic life cycle?
What is an example of an organism with an heteromorphic sporic life cycle?
What it called in the sporic life cycle when the gametophyte and sporophyte have the same morphology?
isomorphic sporic life cycle
What it called in the sporic life cycle when the gametophyte and sporophyte have different morphology?
heteromorphic sporic life cycle
Chlamydonomas participate in what sexual life cycle?
Ulva participate in what sexual life cycle?
Sporic; isomorphic specifically because the gametophyte and sporophyte have the same morphology
