what factors affect the rate of photosynthesis?
Using what you learned on the lab animation, answer the following questions:
• Define a hypothesis that is suggested by the data that are collected in the lab.
• Complete a lab report using the scientific method.
• What effect does the intensity of light have on the rate of photosynthesis (measured as the number of oxygen bubbles)?
• Is it possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions? Explain your answer in detail.
how does light intensity affect the rate of photosynthesis?
In this experiment the photosynthesis rate of a plant.
The binding sites are highly specific and are a critical factor in controlling the rate and Photosynthesis occurs in (1989) Measurement of the extent.
The Influence of Leaf Surface Area on Rates of Photosynthesis in Coniferous and Deciduous Plants.
McCree (1972a) noted that the relative quantum yield for crop plant photosynthesis has two peaks at 440 nm and 620 nm. He also noted however, the , which states that photosynthesis in the presence of two or more wavelengths can be more efficient than the sum of that due to the individual wavelengths. In particular, adding white or red light (less than 680 nm) to deep red light (greater than 680 nm) can beneficially increase the rate of photosynthesis.
Measuring the rate of photosynthesis - Science and …
Assessing the rate of photosynthesis helps us understand why and how plants respond to changes in their environment.
Photosynthesis demonstration Background When we (humans) breath, we use oxygen and give off carbon dioxide in a process called respiration.
Preparing a photosynthesis light response curve.
There are plenty of methods available to measure photosynthesis
We need however to understand each other. As the horticultural industry transitions from high-intensity discharge arc lamps such as high-pressure sodium (HPS) and metal halide (MH) to solid-state lighting (e.g., Massa et al. 2008, Mitchell et al. 2012, Nelson and Bugbee 2014), it becomes possible to tailor the spectral power distribution of multicolor-LED luminaires for individual crops and plant species. For lighting designers working with horticulturalists, the need to understand PAR and calculate PPFD values using lighting design software becomes critical.
we can calculate the rate of ..
The rate of photosynthesis will always correspond to that factor which is in least supply.
Since photosynthesis produces carbohydrates, the rate at which the amount the carbohydrates change is positive for photosynthesis, that is, the amount increases.
