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.
Which of the following are stages in the life cycle of a fern?
The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes.
What are the 4 characteristics of ferns?
Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
Which of the following is the first stage of the life cycle of a fern?
The fern begins with the haploid stage as a spore. The spore will undergo mitosis in order to create many identical haploid cells. This group of cells is called the gametophyte.Jan 27, 2022
What are the two main stages of a fern life cycle?
The life cycle of fern has two different stages, namely sporophyte, and gametophyte. Sporophyte releases spores, and they are diploid, gametophyte releases gametes, and they are haploid. So ferns undergo two generations of plants to complete their life cycle, a life cycle that is called the alternation of generation.
What is the process of fern?
There are two distinct stages of the fern life cycle. Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli. Male and female cells are produced on these plants and after fertilisation occurs the adult fern begins to develop.
Which life form forms first when a fern spore germinate?
If moisture is plentiful, the sperm swim to archegonia - usually on another prothallus because the two kinds of sex organs generally do not mature at the same time on a single prothallus. Another method for promoting cross-fertilization: The first spores to germinate develop into prothallia with archegonia.Dec 31, 2020
What is the most lifecycle in the fern Lifecycle have in common?
Answer and Explanation: Both mosses and ferns have gametophyte and sporophyte stages in their life cycle.
What kind of life cycle does a fern have?
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 do all plant life cycle have in common?
All life cycles have a few things in common: they start with seeds, eggs, or live birth, then involve multiple steps including reproduction, and then they end in death.
How is the life cycle of a fern similar to that of a moss?
Both mosses and ferns undergo alterations of generations. That means both are spore-producing plants. The gametophyte is prominent is mosses, but the sporophyte is prominent in ferns. The sporophyte of ferns is differentiated into true leaves, stem, and roots.Sep 2, 2017
