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.
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.
They have this thing called homins which act like a seed but can reproduce very easily.
The summers are very short

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

A seedless plant has no seeds. A seed plant have seeds. It is very simple.
No, orchids are flowering plants that produce seeds (very small seeds) in seed pods.

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.
no
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.
