In plants, the reproductive cells of the male are called _________ and the reproductive cells of the female are called _______. Male cells are located in the ________. Female cells are located in the __________.
|
Speam, egg, antheridia, archegonia

|
What are the steps in the Marchantia (Liverwort) life cycle?
|
1. Male gametophyte plant releases sperm in water droplets2. Female gametophyte plant catches sperm in archegonial receptacles.3. Sperm+Egg = Diploid Zygote in the archegonium 4. Embryo develops (still diploid)5. Mature diploid sporophyte "sac-looking" structure forms on the female gametophyte plant6. Sporophyte relases haploid "meiospores" that mature into male and female gametophytes

Describe the life cycle of a moss
|
1. Mature female and male gametophytes near each other2. Male releases sperm into water droplet, and sperm swims to female egg3. Sperm+Egg=Diploid zygote in the females archegonium4. Diploid zygote grows into an embryo5. Embryo grows into a stalk with a capsule on the top, coming right out of the middle of the mature female gametophyte plant. The capsule has a lid called the operculum. This stalk and capsule are called the sporophyte.6. Inside the sporophyte, meiosis takes place forming haploid spores7. One day the operculum sloughs off, and the "meiospores" are released.8. Meiospores germinate into a "protonema" or baby plant9. Protonema grows into a mature male or female haploid gametophyte
