Botantists do not have a 100% answer to this question. They are always reclassifying organisms because of similarities are always being rethought and questioned. Another problem is that botanists have different ways in which they classify plants.
Traditionally, plants were divided into four divisions: * Thallophyta (bacteria, algae, fungi) * Bryophyta (mosses and liverworts) * Pteridophyta (ferns and cubmosses) * Spermatophyta (seed plants: gymnosperms and angiosperms) One widely used modern system is that proposed by Whittaker in 1978 (the Five Kingdom system). In this system bacteria, algae and fungi are classified in different kingdoms to the plants, which correspond to the old bryophyta, pteridophyta and spermatophyta. This system has also been thrown out in recent years.
This system divides non-extinct plants into 7 groups called divisions (botanists use the word division instead of phylum): Non-vascular plants (plants without a specialised transport [vascular] system): * Liverworts (Hepaticophyta) * Hornworts (Anthocerotophyta) * Mosses (Bryophyta) Vascular, non-seed plants: * Whisk ferns (Psilophyta) * Clubmosses (Lycophyta) * Horsetails (Sphenophyta) * Ferns (Pterophyta) Vascular, seed plants: * Conifers, cycads (Pinophyta) * Flowering plants [angiosperms] (Magnoliophyta)
Phyla is the plural of phylum. One phylum, many phyla.
There are many animals that are not in the Mollusca phylum. Birds, starfish, butterflies, jellyfish, and worms are not part of the Mollusca phylum.
Plantae is a kingdom that has many phyla under it. It is not contained within a phylum.
Invertebrates have nucleated cells and are thus eukaryotes (Domain Eukarya in the Empire of Life). They are multicellular and heterotrophic and thus animalian (Kingdom Animalia). Edward O. Wilson is what one calls a 'splitter' in taxonomy and has split the animal kingdom into about 85 phyla. Most other taxonomists think there are somewhere in the thirties in the realm of 'How many phyla are there ?' Some invertebrate animal phyla are: Phylum Porifera, Phylum Cnidaria, Phylum Ctenophora, Phylum Platyhelminthes, Phylum Annelida, Phylum Mollusca, Phylum Arthropoda, Phylum Echinodermata, Phylum Hemichordata, Phylum Nematoda, Phylum Rotifera, Phylum Kinorhyncha, Phylum Nemertea, Phylum Bryozoa

Sub-phylum is a taxonomic group. A phylum can contain many sub-phylums which contain a huge diversity of species.
