Seeds.
Seedless plants belong to lower ladder of evolutionar sequence. These are called cryptogames (without seeds) and seed bearing plants are called Phanerogames. In cryptogames propagation takes place through spores and gametophytic stage is independent. In phanerogames propagation is through seeds and gametophytes are dependent on sporophytes.
Only seeds have seed coats not plants. Not all seeds have seed coats.
Spores.
They are all seedless vascular plants

Cellulose is not a plant. It is a carbohydrate, a polymer of sugar that makes up the cell wall of all plants.

the spores all seedless plants have it.
They are all seedless vascular plants
There are no seedless vegetables. all vegetables eventually carry seed.
Not all vascular plants have seeds. Some plants (like club mosses) are vascular and produce spores. For example the phylum Lycophyta are club mosses and quill-worts. these plants produce spores but still have vascular roots, stems, and one vascular vein in each leaf.
Yes, all plants contain chloroplasts.
False. Two large groups of plants could be seed plants and seedless plants, or vascular and nonvascular plants. All plants have leaves of some kind or another.
All vascular plants do not bear seeds. For example plants belonging to Pteridophyta are seedless and those of Gymnosperms and Angiosperms bear seeds.
A tree fern is a seedless plant. All ferns are seedless plants. They reproduce by spores instead of seeds.
A seedless plant would be eg a vegetable eg carrot-lettuce but these plants have roots, all fruits and flowers have seeds but vegetables do not.
One of the advantages would be mixing of genes; seedless plant offspring are identical to the parent, and thus all genetically similar offspring are vulnerable to the same factors as the parents ie. genetic deficiencies/bacteria or virus infection. A good example of this is the Irish potato famine.
