What is the term for the haploid form of a plant?
Gametophyte
Are all seed plants heterosporous?
heterosporous means that male and female organs are different. One structure produces eggs and other produces sperm. If a plant has seeds, which contains the embryo, then that clearly means sexual fertilization and a male/female gametophyte had to be involved. In short, yes. All seed plants are hetrosporous by that logic.
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate
Is the gametophyte or sporophyte dominant in mosses?
Kodak camera cables might fit other brands of cameras, but I was unable to find the answer to this question when I searched the Internet. I do know that several cables are compatible, so it is very likely that they are interchangeable.
Summarize the process of alternation of generations?
A sporophyte will produce spores. Spores develop into gametophytes which have one sex (They are either male or female). Gametophytes produce gametes (egg/sperm, depending on sex of gametophyte) The gametes fuse together by fertilization producing a zygote. The zygote develops into the sporophyte and the process starts again. - ThatTechnoKid
How does gymnosperm come in with conifers?
A conifer is a kind of gymnosperm it is one of the 4 groups of gymnosperms
What is the term for the haploid form of a plant?
Gametophyte
What is the ploidy level of endosperm of gymnosperm?
Endosperm of gymnosperm is haploid(ploidy n), develop from megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).
What kind of leaf does a gymnosperm have?
Both types are present in one or the other plant
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.
About one year is required in the gymnosperm to do what?
between pollination and fertilization
What is the haploid called in plants?
The haploid in plants is when there is only one set of chromosomes. There are whole groups of animals that are haploid. These animals include bees, wasps, and ants.
Is a juniper a gymnosperm or angiosperm?
angiosperm Family - Asteraceae Genus - Dracopis (One of these four) Echinacea Rudbeckia Ratibida
Which two plants have cyanobacteria in there roots?
one is the gymnosperm phyla Cycad
How are the reproductive structures of a typical-gymnosperm different from one another?
KSJKDJKJSKJs
One of a large group of plants without flowers or leaves.?
Gymnosperm
What is a gametophyte?
A gametophyte is an organism in the life cycle of a plant that produces haploid gametes. It is the sexual phase of the plant life cycle and is the first stage in the alternation of generations between the gametophyte and sporophyte generations. The gametophyte produces male and female gametes, which are haploid cells that fuse to form a diploid zygote. The zygote develops into the sporophyte generation, which produces haploid spores that divide to form the next generation of gametophytes.
