FERTILIZATION Pairing of gametes Haploid (N) Diploid (2) Figure 5 Figure 5 shows the life cycle of a single celled alga. How will this differ from the life cycle for a bryophyte? a. This life cycle does not involve seeds at any stage. b. This life cycle alternates between a haploid stage and a diploid stage. c. This life cycle only occurs if conditions warrant. d. This life cycle involves both spores and gametes. e. This life cycle requires water to complete the reproductive process.

Answers

1. Answer: Option D is correct
Explanation:
Algae exhibit a haplontic life cycle.
They exhibit a dominant gametophytic generation. The sporophyte is represented by the zygote alone. There is no multicellular sporophyte.
They do not make seeds
Life cycle contains alternating haploid and diploid stages
They require water for fertilization

Bryophytes exhibit haplo-diplontic life cycle.
They exhibit a dominant gametophytic generation. The sporophyte is multicellular and dependent on the gametophyte for attachment and nutrition.
They do not make seeds
Life cycle contains alternating haploid and diploid stages
They require water for fertilization

The sporophyte in bryophytes produces haploid spores.

These haploid spores germinate and produce gametophyte.
