Xylem, What is the function of it
main tissue in plant that deals with the transportation of water and increases in size and strength
what are the different kind of xylem
fibers, tracheids, vessels
Xylem: fibers
structural strength
Xylem: tracheids
water transport, to get it to the smaller areas of the plant
Xylem: Vessels
water transport *the most water, this is more likely to break because there is so much water pressure
which Xylems have the most water flow
vessels> tracheids>fibers
what is the function of the phloem
to transport sucrose, nutrients, etc.
Water is used to transport the materials
(it goes from source to sink(place where needed)
what is a sieve plates
perforated wall between two sieve elements,
what does a sieve plate do
it allows water & organic solutes to flow along the sieve tube
what is the main components of phloem
Companion cells, and sieve cells
what is a sieve cell
an elongated cell whose walls contain perforations (sieve pores) that are arranged in circumscribed areas (sieve plates) and that afford communication with similar adjacent cells.
what are companion cells
A specialized parenchyma cell, located in the phloem of flowering plants and closely associated in development and function with a sieve-tube element.
