How have the sporophyte and gametophyte changed as plants have evolved?
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
Does gametophyte generation depends on sporophyte generation in ferns?
It does not depending on sporophytes generation
Is sporophyte photosynthetic?
Yes, sporophyte is photosynthetic in the immature stage when the sporophyte is still green and have photosynthising cells still in it. It can need up to half its nutrients from the photosynthesis capsule for later in its life.
What is the dominant generation of Bryophytes?
In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell.http://en.wikipedia.org/wiki/Vascular_plants
Does sorus have gametophyte or sporophyte?
gametophyte
What is a example of sporophyte?
Three examples of a sporophyte are Polypodium, mosses, and a pine tree.
Are pine seeds covered by a tissue donated by the original sporophyte?
no
A pine tree is called a sporophyte because it?
Produces Spores
Is the female pine cone a sporophyte?
A pine tree is generally a Sporophyte - a multicellular, diploid, spore-producing organism. However, the created spores are haploid, and thus begin the gametophyte phase, in which the microspores (pollen) and megaspores (female receptors), will combine back into a gamete, and begin the sporophyte stage again. So, the pine tree is mostly sporophyte, but has very small gametophyte parts that create gametes. They're very small, but they're there.
What is the male gametophyte of a pine tree?
A pine tree is generally a Sporophyte - a multicellular, diploid, spore-producing organism. However, the created spores are haploid, and thus begin the gametophyte phase, in which the microspores (pollen) and megaspores (female receptors), will combine back into a gamete, and begin the sporophyte stage again.
Which generation in the life cycle of a conifer represented by a pine tree?
gametophyte as well as sporophyte generation
What is the first cell of the sporophyte generation in the life cycle of a pine tree?
the first cell in sporophytic generation is the zygote
What is the main plant in gymnosperms?
When you see a pine tree, or a spruce, or a cone-bearing shrub, the "main plant" is a sporophyte
What is the main plant gymnosperms?
When you see a pine tree, or a spruce, or a cone-bearing shrub, the "main plant" is a sporophyte
What does a pine seed contain?
Pine nuts contain, depending on species, between 10-34% protein, with Stone Pine having the highest content. They are also a source of dietary fiber. The nutrition is storembryo (sporophyte) in the center.
What stage is dominant in ferns?
the Sporophyte generation
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
