Incorrect statement about Haplo-diplontic life cycle

Introduction

Haplo-diplontic life cycle is a type of life cycle exhibited by some plants, where both the haploid and diploid stages are multicellular and have independent existence.

Incorrect statement

Option D, which states that Ectocarpus exhibits haplo-diplontic life cycle, is incorrect.

Explanation

Ectocarpus is a brown alga that exhibits a diplontic life cycle. In this life cycle, the sporophyte is the dominant phase and produces haploid zoospores through meiosis. These zoospores grow into haploid gametophytes, which produce gametes through mitosis. Fertilization of the gametes results in the formation of a diploid zygote, which grows into the sporophyte.

Correct features of Haplo-diplontic life cycle


  • Both sporophytic phase and gametophytic phase have equal life time

  • Both sporophytic and gametophytic phases are multi-cellular and have independent existence

  • This kind of life cycle is exhibited by Pteridophytes and Bryophytes



Conclusion

In conclusion, the correct statement about Haplo-diplontic life cycle is that it is exhibited by Pteridophytes and Bryophytes, and both sporophytic and gametophytic phases are multicellular and have independent existence. The incorrect statement is that Ectocarpus exhibits haplo-diplontic life cycle.
