The diploid phase of the human life cycle begins with?
fertilization
What are the main steps in the diploid life cycle?
The main steps in the diploid life cycle are: meiosis, to gametes, to fertilization, to zygote, to diploid individuals, to a reproductive cellIf you are mainly concentrating on the steps I guess you could say Meiosis and Fertilization.
What is a land plant that produces flagellated sperm and has a sporophyte dominated life cycle?
fern
Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?
Meiosis maintains the normal diploid number by halving the number to make the gametes and then allowing the diploid number to be restored through fertilization. For example in humans: Germ cells undergo meiosis --> Sex reproduction 2n germ cells --> 1n gametes --> 2n fertilization
What are the two stages of plant life?
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
When does fertilization occur during the gymnosperms life cycle?
it occurs when it occurs
What are the steps in the diploid life cycle?
The steps in the diploid life cycle are meiosis, to gametes, to fertilization, to diploid, to reproductive cell. The main steps are Meiosis and Fertilization.
What life cycle components appear only in mosses and ferns?
cheater.
The diploid phase of the human life cycle begins with?
fertilization
What does the life cycle of a frog begin with?
External fertilization of many eggs
What process produces the 2N sporophyte in the moss life cycle?
fertilization
What are the stages of the plant life cycle?
firstly pollination then followed by fertilization then by germination

What stage of a ferns life cycle do you see fiddleheads?
You will see fiddleheads in the first stage known as transition in the life cycle of a fern. The fiddleheads are delicately divided when they expand into fronds.
Is fern is biannual or perennial?
No Ferns are not annuals, annuals are angiosperms which have a short life-cycle (one season/ year or less). Ferns belong to the Plantae division Pteridophyta
What is a land plant that produces flagellated sperm and has a sporophyte dominated life cycle?
fern
