Transport in flowering plants Flashcards
topic 2 H .2
the phloem and xylem make up the transport system of
vascular plants
the role of the xylem is to
transport water and mineral ions from the roots to the shoots of the plant
the xylem is formed from
dead cells reinforced by lignin, which provides a route for the column of water to move through the plant by transpiration
the cell wall in the xylem is
broken down
the walls in the xylem are thickened by
lignin
the xylem has contents of
continuous column of water
role of the phloem is to
transport sucrose and amino acids throughout the plant
phloem is formed by
living cells forming a tube with small holes through which substances can move
root hair cells contain _____ which releases energy for active transport
mitochondria
root hair cells increase ___ ____ of plant roots, increasing the rate at which water and minerals can be taken up
surface area
how do root hair cells take up mineral ions and water from the soil
Roots hair cells take up mineral ions from the soil by active transport
The water concentration of the cell cytoplasm is reduced due to the presence of mineral ions
Water moves into the root hair cell by osmosis
water moves into the root hair cells by
osmosis
water moves into the root hair cells through the __ ___ and into the ___
root cortex
xylem
once water has gotten into the xylem, it is carried up to the ___ where it enters ____ cells
leaves
mesophyll
pathway of water through plants
root hair cells
root cortex cells
xylem
leaf mesophyll cells
