In gymnosperms, the haploid structures are primarily the gametophytes, which develop from spores. Specifically, the male gametophyte is found within pollen grains, while the female gametophyte is located within the ovule. These gametophytes produce the gametes (sperm and egg cells) necessary for fertilization, completing the life cycle of gymnosperms.
What else can I help you with?
What structure in gymnosperms and angiosperms becomes a seed?
the ovule {ovary}
What does an archegonium produce?
the archegonium structure produces haploid egg cells (the female reproductive structure-think "egg" like archEGonium) wheras the antheridium produces haploid sperm cells (the male reproductive structure)
What structure or stages in the life cycle of a plant are haploid?
chlorophyll
In moss the green leafy stuff is haploid or dipliod?
In moss, the green leafy stuff is haploid. Mosses have a life cycle that alternates between a haploid gametophyte stage (the leafy green structure) and a diploid sporophyte stage.
What is gametangium?
A gametangium is a structure in fungi, algae, and some plants that produces and encloses gametes for sexual reproduction. It can contain male gametes (sperm) or female gametes (eggs) or both. Gametangia are often specialized structures that allow for the fusion of gametes to create a zygote.
Which haploid structure grows into the haploid generation of a plant?
Seed
What structure do angiosperms and gymnosperms have?
An enclosed ovary
Reproductive cells have 23 chromosomes. Which term describes this structure?
Haploid
What structure in gymnosperms and angiosperms becomes a seed?
the ovule {ovary}
What does an archegonium produce?
the archegonium structure produces haploid egg cells (the female reproductive structure-think "egg" like archEGonium) wheras the antheridium produces haploid sperm cells (the male reproductive structure)
Which structure is found in a angiosperms but not gymnosperms?
Flowers are a structure found in angiosperms but not gymnosperms. Flowers are reproductive structures that produce seeds enclosed within a fruit, a unique feature of angiosperms. Gymnosperms, on the other hand, have naked seeds that are not enclosed within a fruit.
What structure or substance is used in the reproduction of both gymnosperms and angiosperm?
pollen and ovules
What structure or stages in the life cycle of a plant are haploid?
chlorophyll
In moss the green leafy stuff is haploid or dipliod?
In moss, the green leafy stuff is haploid. Mosses have a life cycle that alternates between a haploid gametophyte stage (the leafy green structure) and a diploid sporophyte stage.
Are archegonia haploid or diploid?
Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.
Which sorts of plants undergo sexual reproduction?
Any plant that produces haploid gametes can be said to undergo sexual reproduction. The process involves the "joining" of two haploid gametes to form a diploid embryo (or zygote). Pretty much all plants that produce flowers (Angiosperms) or cones (Gymnosperms) produce pollen and eggs (which are the haploid gametes).
What is gametangium?
A gametangium is a structure in fungi, algae, and some plants that produces and encloses gametes for sexual reproduction. It can contain male gametes (sperm) or female gametes (eggs) or both. Gametangia are often specialized structures that allow for the fusion of gametes to create a zygote.
