Xylem & Phloem
Xylem vessels are water conducting tubes of the plant
Sieve tubes are found in the phloem of Angiospermic plants.
A large group of plants characterized by the presence of specialized conducting tissues (xylem and phloem) in
i think a nonvascular does have stomata becuz they have to be able to breath and stay alive in order to develop spores.they have to go through a life cycleand gthey drop spores and the sproes have to grow in the ground or sprout.then they grow a plant that comes out of a spore.spores can be transpoted to any where they go .they can get carried by wind,birds or water as long they are in the ground .

Do all the plants have tubes that move water and nutrients to all of their organs?
tubes
"Xylem" is the tissue that conducts water in plants.
Xylem (water-conducting cells) are dead (no cytoplasm), and form long tubes called vessels (no end walls) The walls are thickened with ligninPhloem (food transport cells) are living (have cytoplasm) There are two cell types - sieve tubes which conduct the food - they have end walls with perforations (sieve plates) and have no nucleus and companion cells - they don't conduct food but have a nucleus and they support the sieve tubes

vascular
The xylem is the conducting tissue in vascular plants which carry water and nutrients upward. The xylem is made up of protoxylem and metaxylem.
There are two different types of water conducting tissues in vascular plants, both of which are constituted as xylem, they are tracheids, and vessel elements. Tracheids are found only in gymnosperms (vascular, non-flowering plants, such as pines), while both types may be found in angiosperms (flowering plants), however, in some cases angiosperms may only have xylem vessels, it depends on the species.
ricca and marchantia are two plants without tubes they are also non-vascular
