What is the first stage of a fern cycle?
The first stage is that of
the gametophyte
. Spores are produced on the underside of mature plants. These will germinate and grow into small, heart-shaped plants called gametophytes. The gametophytes produce both sperm and egg cells, and will fertilize itself, or others.
Which of the following are stages in the life cycle of fern quizlet?
The life cycle of a fern includes both
a gametophyte and sporophyte generation
. A diploid zygote formed on the gametophyte develops into a sporophyte, a fern. The sporophyte releases haploid spores that germinate into gametophytes.
What are the two main stages of a ferns life cycle?
Reproduction by Spores
Ferns and horsetails have two free-living generations:
a diploid sporophyte generation (spore-producing plant) and
.
a haploid gametophyte generation (gamete-producing plant)
.
What are the steps of the fern plants life cycle?
The life cycle of the fern has two different stages;
sporophyte, which releases spores, and gametophyte, which releases gametes
. Gametophyte plants are haploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.
What is the lifespan of a fern?
Lifespan of fern depends on the species. Some types of ferns can
live up to 100 years
.
Where do ferns grow best?
Woodland ferns do best in
high or dappled shade
. The open shade of mature trees or the north side of the house or a wall, open to the sky, provide nearly ideal light conditions. Most woodland ferns will adapt to relatively low light levels, but no ferns thrive in deep shade.
How do you tell if a fern is male or female?
Scientists previously knew that the factor that determines which sex a specific fern will end up as is a hormone called gibberellin. If the hormone is present in large enough quantities as the plant develops,
the fern usually becomes a male
, and if it isn’t, it becomes a female.
Does mold have a life cycle?
The life cycle of mold can follow different patters. A common, 4 step, life cycle for mold is:
Spore, Germ, Hypha, and Mature Mycelium
. 1. Spore: Spores are released from mature mycelia through spore liberation, the process by which spores break off, or detach, from the structure that germinated the spores.
Does grass have a life cycle?
Annual grasses go through one full life cycle in about a year’s time
and restart a new cycle by dropping seeds and starting a new generation of plants the following year. Perennials, on the other hand, may go dormant in the cooler months, but they always return to their deep green state once warmer days arrive.
Which stage is dominant in the fern 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 type of life cycle does a fern demonstrate quizlet?
No, the life cycle does not include two multicellular stages. Ferns and humans use the same process to form a zygote. The fern stage on the right side of the life cycle is single-celled. This life cycle shows
alternation of generations
.
Do ferns and humans use the same process to form a zygote?
The fern stage on the right side of the life cycle has one set of chromosomes per cell. … This life cycle shows alternation of generations.
True
.
Ferns and humans use the same process to form a zygote
.
What are the 5 stages of plant life cycle?
There are the 5 stages of plant life cycle. The
seed, germination, growth, reproduction, pollination, and seed spreading stages
.
Why are ferns dependent on water?
The sperm needs to swim through water in order to get to the eggs
. The eggs are housed or maintained in the gametophyte. And that dependence on water is why ferns are so often linked to wet habitats.
How many stages are in a plant life cycle?
The plant life cycle consists of
four stages
; seed, sprout, small plant, and adult plant.
