3.1-3.4 Flashcards
Conditions
Physic chemical features of the environment like temperature humidity and ph
Response curve
Illustrates a species preferred and necessary limits for conditions like temperature, ph etc
Thermophiles
Hot loving species
Photoperiod
The period of of daylight within daily cycle
Acclimatization
When conditions trigger a response for species
Phenology
The recording of changing behaviour through seasons
Thermophiles
Temperature loving species
Photoinhibition
the decrease in photochemical efficiency experienced in response to intense illumination due to radiation damages
Avoiders
A strategy to avoid the condition at hand. Ex. Desert plants concentrate photosynthetic activity for when water is available
Tolerators
Slow down systems to tolerate conditions. Long leafed plants tolerate droughts but there photosynthetic period is slower at its peak because leaves are longer
Deciduous
Trees that drop leaves at least once a year
C3 pathway
Calvin cycle: produce 3-carbon acid called 3-phosphoglyceric acid (PGA) as a first product during carbon dioxide fixation.
C4 pathway
where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in ‘bundle sheath’ cells around Rubisco
CAM Crassulacean acid metabolism
CAM plants open their Stomata at night and absorb carbon dioxide and fix it as malic acid they close during the day and release carbon dioxide internally for photosynthesis
Autotrophs
Also known as primary producers, their major resources are photosynthesic radiation, water, nutrients, and carbon dioxide. They don’t need to eat other things
