Alteration of Generations Quiz- 9.51

What is alteration of generations in plants?

• The alternation between a multicellular haploid and a multicellular diploid phase in the plant's life cycle.

• The transition from asexual to sexual reproduction in plants

• The process of changing plant species over time

• The development of new plant species through genetic mutation

What are the two distinct multicellular phases in the life cycle of plants?

• Gametophyte and Sporophyte

• Leaves and Fruits

• Root and Stem

• Seeds and Flowers

What is the purpose of the gametophyte in plants?

• To prevent reproduction altogether

• To produce the same type of spores

• To only allow for asexual reproduction

• To produce gametes.

What is the difference between the gametophyte and sporophyte generations in plants?

• The gametophyte generation produces gametes, while the sporophyte generation produces spores

• The gametophyte generation is the dominant generation in plants, while the sporophyte generation is the recessive generation.

• The gametophyte generation is diploid, while the sporophyte generation is haploid.

Explain the process of fertilization in the context of alteration of generations in plants.

• The process of fertilization in plants involves the fusion of two diploid cells to form a haploid zygote.

• The process of fertilization in the context of alteration of generations in plants involves the fusion of a haploid sperm cell with a haploid egg cell to form a diploid zygote.

• Fertilization in plants occurs through the fusion of a diploid sperm cell with a diploid egg cell.

• In the context of alteration of generations in plants, fertilization is the process of asexual reproduction through spore formation.

Describe the role of spores in the alternation of generations in plants.

• Spores play a key role in the alternation of generations by producing the gametophyte generation in plants.

• Spores are not involved in the alternation of generations in plants

• Spores only produce the sporophyte generation in plants

• Spores have no role in the reproductive cycle of plants
