The correct answer is A. The process of meiosis produces haploid cells. Cell division occurs in all living organisms but there are different types of division depending on if an organism undergoes asexual or sexual reproduction. Meiosis is how some sexually reproducing organisms can form sex cells or gametes.

...
| Difference Between Gametophyte and Sporophyte | |
|---|---|
| Sporophytes | Gametophytes |
| Sporophytes have two sets of chromosomes | Gametophytes have a single set of chromosomes |

What is a sporophyte and gametophyte?
Which statement best describes the hypothesis for why high atmospheric CO2 limited evolution of large Megaphylls?
What does gametophyte dominant mean?
In nonvascular plants, like mosses, the gametophyte generation is the dominant generation. This means that the gametophyte is larger in size and lives longer than the sporophyte generation. So when you are looking at the green leafy part of a moss, this is the gametophyte generation.Sep 15, 2021

What is the dominant stage of the life cycle in both mosses and ferns?
a. The gametophyte is the dominant stage of the life cycle in both mosses and ferns. In both mosses and ferns, moisture is required for sperm to reach the egg.
Which process produces gametes?
a. The process of meiosis produces gametes
What is the dominant stage of a moss?
In mosses, the gametophyte is the dominant stage of the life cycle; in ferns, the sporophyte is the dominant stage of the life cycle. In both mosses and ferns, moisture is required for sperm to reach the egg. Label this structure on the diagrams of a moss. a.
Where do haploid eggs form?
iii. Haploid eggs form in archegonia, and haploid sperm form in antheridia
What are the four groups of gymnosperms?
Like other land plants, gymnosperms have a life cycle called alternation of generations. The four main groups of gymnosperms are cycads, ginkgos, gnetophytes, and conifers. Cycads have palmlike leaves.
How do haploid spores form?
1) Mature Sporophytes produce haploid spores, dispersed by wind. 2) Separate spores develop into femal and male gametophytes. 3) Haploid eggs from in archegonia, and haploid sperm form in antheridia. 4) Haploid gametes undrgo fertilization, forming a diploid zygote. 5) The diploid xygote develops into a sporophyte.
What is the process of meiosis?
The process of meiosis produces haploid cells. Spores, which are haploid, grow by mitosis to become haploid gametophytes. The gametophyte produces eggs by mitosis; eggs are also haploid. ... Life cycle of a Moss. 1) Mature Sporophytes produce ha ploid spores, dispersed by wind.

Do conifers have seeds?
Conifers, including redwoods, pines, and cypresses, have need le-like or scaly leaves and produce seeds in cones. Gymnosperms undergo alternation of generations, alternating between the diploid sporophyte and the haploid gametophyte. In conifers, the mature sporophyte produces two types of cones, in which diploid microsporangia ...
Which generation of the plant life cycle always produces spores?
The diploid generation of the plant life cycle always produces spores.
When did plants evolve?
Plants evolved from green algae about 475 million years ago.
What are the spores of mosses made of?
The sporophytes of mosses are made up of a foot, a seta, and a sporangium. The foot is embedded in the gametophyte and absorbs nutrients from it. The seta, or stalk, transports the nutrients to the sporangium, which produces spores.
What are nonvascular plants?
Nonvascular plants (informally called bryophytes) generally live very close to the ground, sprawling out rather than growing upward. This growth form is due to their thin body parts and lack of vascular structures that would support upward growth. Three phyla of bryophytes exist today: liverworts, hornworts, and mosses.
What are rhizomes?
Rhizoids, which resemble the roots of vascular plants, anchor the gametophytes to a substrate. Rhizoids are not vascular structures.
Why was sporopollenin developed?
the development of sporopollenin to prevent the desiccation of zygotes. Without sporopollenin, plant reproduction on land would have been much more difficult. This was one of the first problems that had to be solved in order for plants to take advantage of the habitats available on land.
What would have happened if there was no sporopollenin?
Without sporopollenin, plant reproduction on land would have been much more difficult. This was one of the first problems that had to be solved in order for plants to take advantage of the habitats available on land.
What is the environment that is required for sexual reproduction?
E)A moist environment is required for sexual reproduction.

Which organism produces many times the number of spores produced by microsporangia?
E)Megasporangia produce many times the number of spores produced by microsporangia.
Is all of the listed responses correct?
A) All of the listed responses are correct.
Is a gametophyte dependent on a sporophyte?
A)The gametophyte remains attached to and dependent on the sporophyte.
