What is the major difference between the gametophytes of a seedlees plant and a seed plant?
Seed plants are flowering plants so they product pollen that land on the female ovule and then produce a pollen tube that releases 2 sperm to fertilize the ovum and the polar nuclei and these form into a seed. In other seedless plants like algae and mosses the plants produce spores which are similar to pollen and many different versions of female gametes. To be honest seedless plants have many different life cycles that are much more in depth so the fertilization process and the maturation of the plants are very different.
Why is it beneficial to have the sporophyte generation dominant in vascular plants?
One possible reason that stands out is that the sporophyte phase has anadvantage over the gametophyte phase because it is diploid rather than haploid.Having two sets of genes can avoid expression of deleterious traits.The seed plant pattern of large sporophyte is a very effective system. Rememberthe key features:1. Large sporophyte nurtures the tiny female gametophytes.2. There are millions of tiny male gametophytes (pollen) that can be carriedgreat distances, either by wind or by animals.3. New sporophytes arise from very mobile, usually very tough, seeds thatcontain energy supply and tiny plant in suspended animation.
Flowering tundra plants must bloom and set seed quickly because?
The summers are very short
Could Vascular plants without seeds grow very large?
no
What are large plants with very tough strong stems called?
Plants with very tough, strong stems are called woody plants. These plants have hard, rigid stems made of wood that provide support and structure for the plant. Examples of woody plants include trees, shrubs, and some vines.

What features are possessed by seeds that are dispersed by wind?
This feafeatures are possessed by some plants use wind as the way of seed dispersal . they produce large numbers of seed which are very light and contain feather like structures such that they can have large distances
Differences between ferns and seed plants?
A seedless plant has no seeds. A seed plant have seeds. It is very simple.
Are orchids spore bearing plants?
No, orchids are flowering plants that produce seeds (very small seeds) in seed pods.

What is a very large region with its own plants and animals?
Biome
Can you plant irises from seeds?
No, an Iris is grown from a bulb not a seed. They will grow very fast since bulbs do not require he germination period that seed type of plants need.
Could Vascular plants without seeds grow very large?
no
How does the soil acidity affects the seed germination?
If the acidity of soil is too high, the germination of a seed will either be slowed or the seed may not grow at all. Some plants are very sensitive to the level of acidity in the soil and need to be treated carefully.
Does salvia divinorum have flowers?
Salvia divinorum does flower, but it is very difficult to start a plant from seed. Usually, plants are cloned from cuttings.
