vascular plant structure and function

Question 1

2 tissues in vascular plants for transport and what are their functions

Answer 1

xylem: transport water and mineral nutrients

Phloem: transports products of photosynthesis

Question 2

purpose of the shoot system

Answer 2

xylem and phloem
transports resources

absorbs oxygen and carbon dioxide

reproduction and carrying out of photosynthesis in leaves

Question 3

purpose of the root system

Answer 3

involves xylem
absorb water and nutrients from the soil.

water via osmosis

nutrients via diffusion or active transport in the form of ions

Question 4

features of xylem (substance, direction, source and structure)

Answer 4

transpiration
substance: water and mineral nutrients

Direction: roots to leaves (one way)

source: absorbed via osmosis from root hair cells

Structure of walls: tubular, elongated, dead xylem tissue forms wood

Question 5

features of phloem (substance, direction, source and structure)

Answer 5

Translocation
substance: products of photosynthesis (usually in form of sucrose)

Direction: from either leaves or roots to were they are needed (both ways)

source: photosynthetic cells or storage tissue

Structure of walls: long and thin with large pores (and companion cells)
