2. Acclimation
adaptation to a new climate (a new temperature or altitude or environment)
Starts late summer (when the days get shorter/nights get longer)
Chemical change occurs causing plants to withstand colder temperatures

3. A Process
Acclimation is a process which when started certain metabolic changes take place.
respiration increases
protein levels increase
enzyme activity increases
water level drops
starch levels doubles
level of ATP (the plants energy source) increases
leaves drop

5. What is happening
Water moves from the cell membrane past the cell wall to the spaces in-between the cells
The water freezes forming ice crystals outside
More space for the crystals so as not to puncture the cell wall
The more airspace the lower temperature a plant can survive

6. Each Plant Is Different
Plants acclimate different, depending all different factors, such as type and climate.
Evergreens are believed to still photosynthesize because they never loose their needles.
Weather also can play I vital role on whether or not a plant survives.
