What else can I help you with?
What group of plants was becoming dominant as humans evolved?
Okay first of all, humans did NOT evolve from monkeys or anything like that. So there were NO plants that became dominant as humans evolved. Evolving is for dummies!! :0)
What were the forests like when it was the dinosaur times?
Forests consisted of the plants of the time. The dominant trees were conifers; some of these conifers that still exist today include Auracaria and Sequoia. There were also cycads, ferns, seed ferns, horsetails, and mosses. Toward the end of the Mesozoic, flowering plants such as palms and primitive grasses evolved.
Where does the carbonifeous period get its name?
Giant ferns and other plants formed vast swampy forests, the remains of those ancient plants formed thick deposits of sediment that changed into coal over millions of years giving carboniferous its name
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.
How long ago did plants evolved?
Plants evolved around 750 million years ago.
What are the forests like?
forests have a lot of trees plants and animals.
What are plants that live in rain forests?
same plants we have
Is tropical soil infertile?
Yes, this answer covers rain forests, which indeed have tropical soil. Rain forests are known for their large amount of rain fall. This results in poor soils due to the leeching of soluble nutrients. The deeply weathered ground creates infertility. Rapid bacterial decay prevents humus from forming. The concentrations of iron and aluminum oxidize and can produce mineral deposits. The only reasoning for high plant variety and density in infertile soil is because of the organic matter decay the plants will absorb, and the heavy humidity and rainfall, provide the certain plants with what they need, even in infertile soil, they just evolved that way. They evolved to not depend so heavily on the infertile soil but more on other methods such as the mineral deposits I mentioned before, and when they evolved this way, the environment that they evolved to live in are very providing to these plants resulting in the high density forests we see today.
As land plants evolved what generation become more dominant A Gametophyte B Sporophyte C both D neither?
In lower plants gametophytic generation was dominant and as the evolution progressed the gametophytic generation became progressively reduced and ultimately became dependent on sporophytic generation. Thus as the evolution progressed sporophyte become more dominant.
Where did seeds come from after the earth cooled down?
plants with seeds evolved from simpler plants which evolved from single celled organisms
Why do flowering plants evolved after cone-bearing plants?
Yes
How do plants survive in this climate?
They evolved to.
