What generation is dominant in both gymnosperms and angiosperms?
The dominant generation in gymnosperms is the sporophyte generation, while in angiosperms it is also the sporophyte generation. The sporophyte generation produces the structures that we commonly recognize as trees, shrubs, and flowers in plants.
Do the spores belong to the gametophyte or the sporophyte generation?
Spores belong to the sporophyte generation in the plant life cycle. They are reproductive structures that develop from sporangia on the sporophyte and give rise to the gametophyte generation through germination.
What constitute the sporophyte in pine?
In pine trees, the sporophyte generation consists of the adult tree itself, including the roots, trunk, branches, and needles. The sporophyte produces reproductive structures called cones, which contain the spores that will develop into the next generation of gametophytes.
Why is the seta and capsule known as the sporophyte generation?
The seta and capsule are known as the sporophyte generation because they are structures that produce spores through meiosis, which will ultimately give rise to the gametophyte generation. The sporophyte generation is diploid, meaning it contains two sets of chromosomes, whereas the gametophyte generation is haploid, containing one set of chromosomes.
What is the sporophyte stage of ferrns?
The sporophyte stage of ferns is the dominant stage in their life cycle. It is the diploid phase where spore-producing structures called sporangia develop on the underside of the fronds. Spores are released from the sporangia and germinate into a new gametophyte plant.
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
Where does meiosis occur in seedless plants?
Meiosis typically occurs in the specialized structures called sporangia or sporophylls in seedless plants. These structures are found on the sporophyte generation of the plant, where meiosis takes place to produce spores.
What does the sporophyte grow out of?
In moss, where the sporophyte grows directly out of the top of the gametophyte.
What is a example of sporophyte?
Three examples of a sporophyte are Polypodium, mosses, and a pine tree.
In a moss the gametophyte stage depends on the sporophyte stage for nutrients.?
The sporophyte stage depends on the gameophytestage because the gameophyte stage has a photosynthic stageand because the sporophyte stage lives shortly.
Where are sporophylls found?
Sporophylls are found on the sporophyte generation of plants, which is the diploid phase of the plant life cycle. They are specialized leaves that bear sporangia, the structures that produce and contain spores. Typically, sporophylls are found in the reproductive structures of plants like cones or flowers.
In flowering plants the sporophyte does what?
Flowering plants do not have a sporophyte. They have antheridium and archegonium to produce their gametes. Sporophyte is found in ferns, mosses, club mosses, lycophytes, etc but not in flowering plants. Flowering plants produces pollen while a sporophyte produces spores
