In ferns, the alternation of generations involves a prominent gametophyte stage that is independent and photosynthetic, producing gametes. In contrast, in pines (a type of gymnosperm), the dominant sporophyte generation is the visible plant, while the gametophyte is reduced and dependent on the sporophyte, developing within the ovules and pollen grains. Additionally, ferns reproduce via spores that develop into gametophytes, while pines produce seeds that develop from fertilized ovules, showcasing a more complex reproductive strategy.
What else can I help you with?
What stage of alternation of generations is represented by fern fronds?
please answer
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)
What is the name to the gametophype generation in fern?
Gametophyte generation of fern is called prothallus.
How is a parent generation of a fern different from the generation that comes before or atfer it?
Henry is the man is go in the house so he can be with me
Are the cells of fern that you see haploid or diploid?
The cells of a fern plant that you see are diploid. Ferns have a lifecycle which alternates between a diploid sporophyte generation and a haploid gametophyte generation. The visible fern plant is the diploid sporophyte generation.
Which generation of the fern plants is said to be the haploid generation?
The gametophyte generation of fern plants is the haploid generation. It produces gametes (eggs and sperm) through mitosis. When the gametes fuse during fertilization, they form a diploid zygote that develops into the sporophyte generation.
What is a seed like object that falls fom a fern and will grow into a new fern?
The seed-like object that falls from a fern is called a spore. Unlike seeds from flowering plants, ferns reproduce using spores, which are typically produced in clusters on the undersides of their fronds. When the spores are released and find a suitable environment, they can germinate and grow into a new fern through a process called alternation of generations.
How many chromosomes does a fern tree have?
Different ferns have different numbers. Here are some examples: Grape fern -- 90 Rattlesnake fern -- 184 Adder's-tongue fern -- 1260
Which of these is not a gymnosperm Fern Cycad Pine or Ginkgo?
Fern is not a gymnosperm. Ferns are a group of plants that belong to the division Pteridophyta, whereas gymnosperms include cycads, pines, and ginkgoes. Gymnosperms are seed-producing plants with "naked seeds" that are not enclosed within a fruit.
How many chromosomes does ferns have?
Different ferns have different numbers. Here are some examples: Grape fern -- 90 Rattlesnake fern -- 184 Adder's-tongue fern -- 1260
What is the scientific answer what is the function of a fern?
The function of any living thing is to pass its genes on to the next generation.
Where are gametes produced in a fern plant?
In fern plants, gametes are produced in specialized structures called gametangia. Male gametes (sperm) are produced in antheridia, while female gametes (eggs) are produced in archegonia. These structures are typically found on the prothallus, which is the gametophyte generation of the fern. The prothallus is a small, heart-shaped plant that grows from spores and is independent of the sporophyte generation.
