Transport Tissues in Plants

Question 1

How are phloem and xylem vessles found

Answer 1

Found together in vascular bundles

Question 2

Function of the xylem vessel

Answer 2

carries water and dissolved minerals from the roots to the photosynthestic part of the plants

Question 3

what is the function of the pholem

Answer 3

transport the dissolved product of photosynehtiss from the leaves to where it is needed

Question 4

is the xylem living or dead

Answer 4

dead

Question 5

is the phlem living or dead

Answer 5

living

Question 6

what does cambimum do?

Answer 6

layer of unspecailsied cells that divide giving rise to more speaclised cells that turn into xylem and pholem

Question 7

How does a xylem vessel form?

Answer 7

-starts of as living tissue with cells arranged in a single collum

-as the stem ages lingin is desposited in cell walls and cells die.

-the end walls between the cells break down and the xylem becomes a hollow tube with no living content

• this allows flow of water and stops the cells from collapsing under suction.

Question 8

how does water move out of the xylem and into the surrounding cells

Answer 8

through the unlignifed areas

or through the specailsied pits, in the walls of the xylem

Question 9

Key features of the xylem:

Answer 9

-transport water and minerals and also provide structual support

• water can only flow upwards

-long cylinders made of dead tissue with open ends therefore they can form a continoous collum

Question 10

What are the phloem vessles involved with

Answer 10

Translocation

Question 11

Key features of the pholem vessel

Answer 11

companion cells are invovled in ATP production for loading sucrose into sieve tubes

STE form a tube to transport sugars such as sucrose in the dissolved form of sap ( transport can be upwards or downards)
