Protoxylem is the first part of the primary vascular tissue in plants called xylem that matures. Its function is to transport water to the shoot in the early stages of the growth of the plant.
Metaxylem is a part of primary xylem that differentiates after the protoxylem.
You get two pairs for less than double and they don't crease but they do not last as long as the plants. Vascular plants have well defined xylem & phloem and is the characterstic feature of Pteridophytes, Gymnosperms and Angiosperms. Non-vascular plants lack xylem & ploem as in case of Algae, Fungi and Bryophytes.
Because sugar is transported through phloem and water is transported through xylem.
Tracheids Vessels Xylem parenchyma Xylem fibres
Because xylem is a vessel that water travels through.
the xylem is in the roots and the phloem is in the stem actually, their is xylem and phloem in the roots. there is a large central core of xylem often in the shape of an x. and the phloem is found in between the arms of the x shaped xylem.
xylem and ploem
Johan Sebastiaan Ploem was born on 1927-08-25.
It's in the stems not the flowers. Xylem and phloem are the pipes in a plant through which nutrients and water travel. Similar to the arteries and veins of a human. The xylem tubes are the pipes through which water and minerals travel from the roots up to every other part of the plant. The phloem are the pipes through which the food (glucose) travels from the leaves to every other part of the plant.

Xylem
it's called "xylem" your welcome
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same .
Vascular plants have xylem
Tracheids Vessels Xylem parenchyma Xylem fibres
Water is transported by the xylem.
