Answer 8

Gametophyte, By Budding

Question 9

How does gametophyte give rise to sporophytye?

Answer 9

• By Reproduction of antherozoid and ovum,

Question 10

Answer 10

• By Asexual reproductions of spores

Question 11

The Life Cycle of A moss

Answer 11

1. Small, green, and leafy is the haploid gametophyte(gamete-bearing plant)
2. Sporogonium is the diploid sporophyte(spore-bearing plant)
3. Most Cases, Gametophyte is the dominant phase
4. When Gametophyte is mature, it develops male and female sex organs at the top of the stem
5. The antheridium produces many long, spiral coiled antherozoids
6. Antherozoids have 2 flagella.
7. After heavy dew/rain, the antherozoid swims through a film of water covering the plant to a nearby flask-shaped female organ called archegonium
8. Archegonium has a large ovum at its base.
9. The ovum releases a chemical substance that attracts and guides the antherozoid down the neck of the archegonium and into the base.
10. The Haploid antherozoid fertilizes the haploid ovum to form a diploid zygote.
