transports sugar down from the leaves
It trans locate food in plants mainly. Also transport some minerals,molecules ,hormones etc
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.
No. Xylem and phloem are belonging to vascular plants only. Bryophytae are not vascular, and do not have these.
Vascular plants. Xylem and Phloem are the vascular system of plants. If you compare it with humans, they're the blood vessels...sort of Xylem transports water, Phloem transports nutrients
Angiosperms (or flowering plants) are terrestrial plants and largely dominate terrestrial ecosystems.

The cambium is a layer of cells in plants that is responsible for lateral growth, producing new xylem and phloem cells. It plays a key role in secondary growth, increasing the width of stems and roots.

Phloem as well as xylem
Phloem is found in plants.
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.

Xylem transports water up from the foots. Phloem carries food down from the leaves. The circulatory system in animals is the closest analogue.
Phloem
Yes, but some plants lack certain types of xylem and phloem cells such as vessel elements and tracheids. Tracheids have been lost in Wolffia, an aquatic plant, and vessels are not present in all conifers.
