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
What constitute the sporophyte in pine?
When a seed germinates, the embryo within it develops into a new tree that constitutes the sporophyte. ........... stupid
What stage is dominant in ferns?
the Sporophyte generation
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
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.
What generation is dominant in both gymnosperms and angiosperms?
gymnosperm- sporophyte angiosperm- sporophyte
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.
Why is the seta and capsule known as the sporophyte generation?
The cap like structure on the capsule of the sporophyte generation in a bryophyte is the operculum. The structure that covers the capsule of the sporophyte in bryophytes is calyptra.
Does gametophyte generation depends on sporophyte generation in ferns?
It does not depending on sporophytes generation
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
Why is the sporophyte stage in mosses is dependent on the gametophyte stage?
The sporophyte stage depends on the gameophytestage because the gameophyte stage has a photosynthic stageand because the sporophyte stage lives shortly.
