Xylem be carrying
Minerals and water from roots to other parts
Process taking place in xylem- carrying water and minerals
Ascent of sap
Phloem be
Form long tubes
Transport of food from leaves to other parts
Process in phloem called
Translocation
Phloem tubes are also called
Sieve tubes
Transpiration
@ plants lose sunlight thru roots due to moisture
# plants lose water in form of water vapour thru stomata
₹ stem goes thru wilting
#
Transpiration occurs in which part
Aerial parts
Leaves try stomata
Transpiration pull be like
Water diffuses into spongy tissue of xylem vessels. Xylem PULLS the water and dissolved minerals to leaves
When do plants lose excess water
Rate of transpiration pull is more than rate by which roots absorb water
Wilting
Drooping of leaves and flower - plant
Root hairs be _______ for water and mineral to enter roots
Passages
What do root hairs do
Increase surface area of roots- absorption of more substances
Water is absorbed by root thru process called
Osmosis

Semipermeable membrane
True or false
Translocation can occur in both upward and downward directions
True
True or false
Movement of water in xylem occurs in downward direction
False
