Detailed explanation-1: -Although the three phylum of seaweed (Brown, Red, or Green) are not classified as plants, they do perform photosynthesis without vascular tissues. They have no xylem or phloem tissues to transport water or nutrients around the plant.

Detailed explanation-2: -Mosses, Liverworts & Hornworts Mosses, liverworts and hornworts are collectively called “bryophytes.” Bryophytes are nonvascular plants: They do not have special tissues-tissues that botanists call “xylem” and “phloem”-to transport fluids and nutrients internally.

Detailed explanation-3: -A liverwort is nonvascular green plant. It does not have phloem and xylem like ferns, conifers and flowering plants to transport water, food and minerals through the plant.

Detailed explanation-4: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Detailed explanation-5: -Xylem transports water and minerals.
