3.2 Specialisation & Organisation of Plant Cells Flashcards
Root and Shoot Systems of Plants
Root systems: absorbs water and minerals and storing food
shoot systems: photosynthesis, reproduction, support and the transport of water & minerals
tissue that makes up the vascular tissue and what each transports
Xylem: transports water and dissolved minerals from roots to the rest of the plant.
- water moves through the xylem via capillary action, cohesion and adhesion.
Phloem: transports organic nutrients, like sugars produced by photosynthesis, from leaves to other parts of the plant.
- transported via a process called translocation, driven by pressure flow mechanisms

how water is taken into, transported and lost from plants
intake: water enters root through osmosis, moving from soil to root cells
transport: water moves through the xylem vessels. capillary action along with adhesion and cohesion, helps transport water upwards.
Loss: Transpiration - water vapour exits through the stomata of the leaves.
