Celery Sucks (VCE SSCE Biology): Flashcards

Loss of water vapour from plant leaves through stomata

Tiny openings in leaves where water is lost to atmosphere

Capillary action, cohesion, pressure differences

High temperatures, wind, low humidity

Transports water & minerals upward from roots to leaves

Transports sugars & nutrients in multiple directions

The factor you deliberately change

What you measure in response to the change

Factors kept the same to ensure fair testing

Dry air creates a stronger gradient for water to evaporate
