3.4 - Transport In Plants Flashcards
Many factors are involved in the transport of ______ in plants
Water
Water molecules cling to each other in what is called ______
Cohesion
Cohesion is due to the polar nature of the ______ molecule
Water
Because of their polar nature, water molecules are also attracted to molecules of other substances in what is called ______
Adhesion
Root pressure
- dissolved minerals are present in the cells of roots as a result of ______ transport
- through the process of ______, water is drawn into the cells creating positive pressure that forces fluid up the ______
- water is forced from a ______ pressure in the roots to a ______ pressure in the leaves
- root pressure is not the only process involved in moving ______ up the plant
Active Osmosis Xylem Higher Lower Water
With ______, as the water is lost in the stems and leaves, it must be replaced, and so the water is “sucked” up the plant
Transpiration
Gases, minerals, and sugars must be ______ in a film of water to be transported in plants
Dissolved
