Multiple Choice
Which of the following statements about the life cycle of plants is true?
A
Plants do not undergo meiosis during their life cycle.
B
Plants alternate between haploid and diploid generations.
C
The diploid generation in plants is called the gametophyte.
D
Plants only reproduce sexually and do not have asexual reproduction.
Verified step by step guidance1
Understand the concept of alternation of generations in plants, which involves alternating between two distinct phases: the haploid (n) gametophyte and the diploid (2n) sporophyte.
Recognize that meiosis is a crucial process in the plant life cycle, occurring in the diploid sporophyte to produce haploid spores, which then develop into the gametophyte.
Identify that the diploid generation in plants is actually called the sporophyte, not the gametophyte. The gametophyte is the haploid generation.
Acknowledge that many plants can reproduce both sexually and asexually. Sexual reproduction involves the fusion of gametes, while asexual reproduction can occur through methods like vegetative propagation.
Conclude that the true statement about the life cycle of plants is that they alternate between haploid and diploid generations, known as alternation of generations.
