Explain the stages in the life cycle of a fern?
A fern's life cycle alternates between two distinct stages: the sporophyte and gametophyte. The sporophyte stage is the dominant phase, where it produces spores through meiosis. These spores germinate into tiny gametophytes, which produce eggs and sperm. Fertilization of the egg by the sperm results in a new sporophyte plant.
Are most adult protists diploid or haploid?
Most adult protists are diploid, meaning they have two sets of chromosomes. This is in contrast to some lower life forms, such as algae, which can have a haploid dominant life cycle stage.
What is the first stage of the umbrella bird life cycle?
A egg
What animal that has a larval stage in their life cycle include?
Caterpillar
What is the difference between the life cycle of ferns and the life cycle of humans?
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. The life cycle of a conifer consists of male and female cones produced on an adult plant, the sporophyte. The male produces pollen grains that fertilize eggs retained within the female cone. The fertilized egg develops into a seed. When released and conditions are favorable, the seed germinates into a young sporophyte.
What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?
in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.
Describe the dominant stage in the life cycle of a fern?
Diploid Sporophyte
Which stage in the alternation of generations life cycle would fern represent?
The Sporophyte life cycle is the dominant stage in Ferns (vascular non-seed plants)
Is the gametophyte stage the dominant stage in a gymnosperms life cycle?
No, the sporophyte stage is the dominant stage in the gymnosperm life cycle. The gametophyte stage is reduced and dependent on the sporophyte for nutrition and support.
What is the dominant stage of the life cycle in primitive plants?
The dominant stage of the life cycle in primitive plants, such as mosses and liverworts, is the gametophyte stage. This is where the plant produces gametes for sexual reproduction. The sporophyte stage is smaller and dependent on the gametophyte for nutrition.
What is a land plant that produces flagellated sperm and has a sporophyte dominated life cycle?
A land plant that fits this description is a fern. Ferns have flagellated sperm that require water for fertilization, and their life cycle is characterized by a dominant sporophyte stage. During fertilization, the sperm swim through water to reach the eggs on the archegonia of the female gametophyte.
Explain the stages in the life cycle of a fern?

These spores germinate into tiny gametophytes, which produce eggs and sperm. Fertilization of the egg by the sperm results in a new sporophyte plant.
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.
What type of eukarytic life cycle does this diagram represent?
The diagram shows a diploid-dominant life cycle, where the dominant stage is diploid and the haploid stage is reduced and often unicellular. Examples include fungi and most animals.
Is it true that the gametophyte stage is the dominant stage in a gymnosperm's lifecycle?
No, in gymnosperms, the sporophyte stage is the dominant stage of the life cycle. The gametophyte stage is reduced and dependent on the sporophyte for nutrition and support.
What is the dominant phase of the bryophyte life cycle?
Bryophytes or Moss plants life cycle goes with two stages. The two stages are the haploid (gametophyte) and the diploid (sporophyte) which is the dominant stage.
What does the gametophyte stage of a moss or fern life cycle produce?
The gametophyte stage of a moss or fern life cycle produces gametes (eggs and sperm) through mitosis. These gametes combine during fertilization to form a diploid zygote, which develops into the sporophyte stage.
