The term that's synonymous with phylum, in the plant world, is division. So the phylum, or preferentially the division, of cactus plants is Magnoliophyta. It's the division for angiosperms, which also are called flowering plants. Flowering plants may develop from an embryo that has one or two leaves. A cactus is a dicotyledon, because it has two embryonic leaves.
Cacti belong to the phylum Tracheophyta, which includes vascular plants that have a specialized transport system for water and nutrients.
Tracheophyta is the phylum in which the saguaro cactus [Carnegiea gigantea] is found. It's the phylum of the tracheophytes, which also are called higher or vascular plants. These plants have specialized tissues for moving around water, minerals and dissolved nutrients, and energizing products from the photosynthetic interaction with sunlight.

Roses belong to the phylum Anthophyta, which is the phylum for flowering plants. Anthophyta includes all the plants that produce flowers for reproduction.
Cactus plants use their stems for storage. So that's where starches are stored. In fact, stems are where a cactus plant stores everything. Other, non cactus plants may use their roots for storage. But cactus roots are much too fibrous and shallow.
