What phase of life cycle do most plants live in?
Depending on the type of plant, most of its life cycle may be spent in either the gametophyte generation or sporophyte generation. Other organisms, such as some algae and fungi, may spend most of their life cycles in the gametophyte phase. Moss Sporophytes.
What is the dominant stage in the bryophyte life cycle?
The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote.
What is the asexual phase of the life cycle of plants?
The zygote develops into a diploid sporophyte, which represents the asexual phase of the cycle. Sporophytes produce the haploid spores from which haploid gametophytes develop. Depending on the type of plant, most of its life cycle may be spent in either the gametophyte generation or sporophyte generation.
What is the dominant phase of the tracheophyte life cycle?
Tracheophytes, unlike bryophytes, have developed seeds that encase and protect their embryos. The dominant phase in the tracheophyte life cycle is the diploid (sporophyte) stage. The gametophytes are very small and cannot exist independent of the parent plant. The reproductive structures of the sporophyte...
What is the dominant phase of the life cycle?
The dominant part of the life cycle, i.e., the plant that is recognized as a fern, represents the sporophyte generation. The gametophyte generation includes the phase of the life cycle between the formation of spores by meiosis and fertilization and formation of the zygote.
What is the dominant stage in the life cycle of a tree?
The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
Which phase is dominant in the life cycle of bryophytes?
GametophyteGametophyte is a dominant phase in the life cycle of a bryophyte.
What is the dominant stage in plants?
Thus, in the higher (i.e., vascular) plants the sporophyte is the dominant phase in the life cycle, whereas in the more primitive nonvascular plants (bryophytes) the gametophyte remains dominant.
Which stage is dominant in the life cycle of gymnosperms?
sporophyteThe simple answer to it is sporophyte. As seen in angiosperms, the gymnosperms too exhibit a dominant sporophyte generation. Like all the vascular plants, Gymnosperms too have a sporophyte-dominant life cycle.
Which of the following is the dominant stage in the life cycle of moss?
the gametophyteIn mosses, the dominant stage is the haploid generation (the gametophyte). This means that the green, leafy gametophytic tissue is haploid (has only one set of chromosomes).
What is a dominant gametophyte?
The gametophyte is the dominant life phase in the Bryophytes. The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively. Collectively these structures are known as gametangia.
Which is the dominant and independent phase in bryophytes?
the gametophyteIt is clear that the gametophyte is the dominant phase in the life cycle of a bryophyte in every aspect. The gametophyte is independent and photosynthetic.
How is gametophyte a dominant phase in the life of?
Answer: Gametophyte is a haploid multicellular adult stage in a bryophyte's life cycle. It bears male reproductive structure (antheridia) and female reproductive structure called archegonia ,and thus produce haploid gametes antherozoids (male gamete) and egg cell (female gamete) respectively.
Which of these two phases is the dominant generation?
The dominant phase in the tracheophyte life cycle is the diploid (sporophyte) stage. The gametophytes are very small and cannot exist independent of the parent plant.
Which is the dominant plant life form sporophyte or gametophyte in the life cycle for each of these groups of plants?
Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. The dominant generation in nonvascular plants is the gametophyte; in vascular plants, it's the sporophyte.
What is a dominant sporophyte?
A sporophyte is a multicellular diploid generation found in plants and algae that undergo alternation of generations. It produces haploid spores that develop into a gametophyte. The gametophyte then makes gametes that fuse and grow into a sporophyte. In many plants, the sporophyte generation is the dominant generation.
