What does ET50 mean in photosynthesis?

What does ET50 mean in photosynthesis?

The ET50 is the time it takes for 50% of the leaf disks to float and is a good indicator of the rate of photosynthesis. It was hypothesized that if the concentration of carbon dioxide was increased, then the rate at which photosynthesis occurs will also increase.

Why do you think 1 ET50 is more useful as indicator of the rate of photosynthesis or cellular respiration than ET50?

This is because the times to float are the inverse of the rate of photosynthesis. Taking the reciprocal of ET50, 1/ ET50 allows the graphic presentation to more closely express the physical phenomenon, as shown in Figure 3.

How do you determine the ET50 of an experiment?

To determine the ET50-light for this trial, plot the percent leaf disk floating as a function of time: From the above graph, we can interpolate that 50% of the leaf disks floated at 5.5 minutes. Therefore, the ET50-light is 5.5 minutes.

What does ET50 mean on a rim?

You could Google it. It’s the distance from the mounting face of the wheel to the centreline. If you coud fit a 13mm spacer to that ET63 wheel, you’d get ET50, for example. Imagine unbolting the wheel and moving it out towards the wheel arch a few mil. That’s what an offset change can do.

Why do you need to add together the 1 ET50 light 1 ET50 RESP in order to determine the approximate photosynthesis rate?

why do you use 1/ET50 light? Why is 1/ET50 light not the actual rate of photosynthesis? 1/ET50 light is the inverse relationship of the actual rate of photosynthesis and must be added with the rate respiration to equal the actual rate. equation for actual rate of photosynthesis?

Does light intensity affect the rate of photosynthesis?

Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.

What will happen if you remove the air from these spaces answers?

If you draw the gases out from the spaces, then the leaves will sink because they become more dense than water. If this leaf disk is placed in a solution with an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur in a sunken leaf disk.

How does light intensity affect photosynthesis experiment?

More oxygen bubbles are produced when the light is closer to the beaker. So a greater light intensity gives a greater rate of photosynthesis.

Is Rim offset important?

Proper offset assures your new package has enough clearance so nothing rubs against the suspension, brakes or vehicle body (like fenders, bumpers and mud flaps). It’s also important for driving safety, since the wrong offset can reduce vehicle stability or interfere with braking.

What are the benefits of the zebra et51 and et56 tablets?

Now you can have it all with the ET51 and ET56 Android or Windows Enterprise Tablets. Your workers get a personal tablet that looks and feels like their own, while you get the durability, ease-of-use, data capture features and flexibility your business requires. The GO Zebra Trade-In Program helps you save money while you modernize your operations.

Why choose the et56 Android or Windows tablet?

Choose Windows or Android platform. When your work takes you off-site, that doesn’t mean you’re out of touch. With the ET56 Android or Windows tablet, you can communicate almost anywhere with fast LTE WAN access. With a weight as little as 1.15 lbs. and a mere 1/2-inch thickness, you’ll hardly know it’s there.

How many Mah is the et51 battery?

Windows: 3300 mAh 7.6V rechargeable Li-Ion; user replaceable (25 Whr) Optional hot swappable 7.2V @ 3400mAh (24.4Whr) For use inside or on grounds with WiFi coverage, the ET51 is thin and lightweight, but will take a drop, a hose-down, or handle sub-zero temperatures.

How do you measure the net rate of photosynthesis?

Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis. Liquid SoapPlastic syringe (10 cc or larger)—remove any needle! Prepare 300 ml of bicarbonate solution for each trial.
