Learning Objectives - Environment and Photosynthesis

Understand that net CO2 assimilation per day = daily net Ps - nighttime RD.

Be able to related to crop growth and adaptation to the equation: net Ps - RD = growth + storage.

Understand the influence of light, temperature, water stress, carbon dioxide, oxygen, wind, and mineral nutrients on photosynthesis, photorespiration, and dark respiration.

Know what is meant by PAR

Understand long-term global trends in atmospheric CO2 and their impact on the greenhouse effect

Understand the impact of leaf angle and canopy structure on photosynthesis and growth.

Understand the concept of light saturation of photosynthesis, including species differences.

Understand sensible and latent heat losses, and their role in cooling leaves

Know what is meant by light compensation point

Understand heliotropic responses, the role of the pulvinus, and how they can alter photosynthesis.

Understand the concept of critical LAI and its impact on CGR

Understand how and why net CO2 uptake of species responds differently to temperature.

Know what fluorescence is and why it occurs in plants.

Know what Q10=2 means in the context of temperature responses of plants.

Understand the concept of water potential and its impact on photosynthesis and carbon assimilation.

Understand WUE and how it is effected by stomatal closure

Understand the impact of transpiration on leaf temperature.

Know how atmospheric CO2 and O2 levels are changing and the impact of this change on CO2 exchange and plant growth

Know and be able to apply Fick's Law of diffusion

Understand the impact of wind on boundary layer effects

Understand factors that contol boundary layer resistance, stomatal resistance, and mesophyll resistance

Know why N, P, K, S, Fe, Mg, Cu, and Ca are required for photosynthesis
