Detailed explanation-1: -Bryophytes such as mosses and algae are non-vascular plants. They do not possess true roots, stems and leaves. Xylem and phloem are absent.

Detailed explanation-2: -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: -The phloem, which transports food, and the xylem, which transports water, are both found in vascular plants. Nonvascular plants are small, straightforward plants that lack a vascular system. They have no phloem or xylem.

Detailed explanation-4: -Nonvascular plants do not have vascular tissues like xylem and phloem, while vascular seedless plants do.

Detailed explanation-5: -Phloem is vascular tissue that transports food (sugar dissolved in water) from photosynthetic cells to other parts of the plant for growth or storage. This type of tissue consists of living cells that are separated by end walls with tiny perforations, or holes.
