How do you calculate the rate of photosynthesis BBC Bitesize?
Investigating the rate of photosynthesis
- Set up the apparatus as in the diagram.
- Leave for five minutes for the pondweed to acclimatise to the new light intensity.
- Count the number of bubbles given off in one minute.
- Move the light 10 cm further back.
- Leave for five minutes for the pondweed to acclimatise again.
How do u calculate rate?
However, it’s easier to use a handy formula: rate equals distance divided by time: r = d/t. Actually, this formula comes directly from the proportion calculation — it’s just that one multiplication step has already been done for you, so it’s a shortcut to learn the formula and use it.
What is the formula for calculating heart rate?
To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm). The 64% and 76% levels would be: 64% level: 170 x 0.64 = 109 bpm, and.
How is rate of reaction calculated?
Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
What are five factors that affect the rate of photosynthesis?
The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors.
What limits the rate of photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
How do you calculate beats per minute formula?
To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. Multiply this number by 4 to calculate your beats per minute.
How do you measure the rate of photosynthesis?
The easiest way to measure photosynthesis rate in this manner is to measure carbon dioxide or oxygen levels using a data logger. We can also measure the rate of photosynthesis by measuring an increase in the plant’s biomass (weight).
What is the equation for the rate of photosynthesis?
The photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. Photosynthesis defines the process by which plants and some bacteria manufacture glucose. Scientists summarize the process as follows: using sunlight, carbon dioxide + water = glucose + oxygen .
How does temperature affect photosynthesis?
When the temperature rises, the particles in the reaction move quicker and collide more, so the rate of photosynthesis rises also. At the optimum temperature, the enzyme is most efficient and the rate if maximum. At temperatures above 40°C the rate slows down.
