Biology - A Balancing Act

A Balancing Act

Plant functions

Plants depend on their immediate environment for the materials and energy
(light) they require for survival. Plants are often subject to conflicting
demands, and a balance must be achieved as they respond to changing
environmental conditions. Different plant functions have to be integrated,
including:

* uptake of water and mineral nutrients from soil or water

* transport of water and minerals from roots

* control of stomatal opening and closure affects CO2 uptake, water loss
and therefore photosynthesis

* maintenance of water and salts balance

* transport of materials (translocation) from sources (where made) to
sinks (where used or stored)

* the cooling of the plant by transpiration
