Common questions

How does green light affect the rate of photosynthesis?

How does green light affect the rate of photosynthesis?

The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as much as the other colors.

Why does rate of photosynthesis decrease in green color light?

The leaves of a plant are green because the chlorophyll within them absorb all other wavelengths of light and reflects green light. It is safe to assume that green would have to lowest rate of photosynthesis because it is reflected by the leaves of plants and red/violet would have the highest rate of photosynthesis.

What is the rate of photosynthesis in green plant?

Plants usually convert light into chemical energy with a photosynthetic efficiency of 3–6%.

Does color affect rate of photosynthesis?

The wavelength of a color is directly related to the rate of photosynthesis, with longer wavelengths leading to higher rates of photosynthesis. Photosynthesis takes place primarily in the leaves of plants.

What factors affect the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

How can the rate of photosynthesis be measured?

Theory of Measurements: Leaf photosynthetic rate is measured by enclosing a leaf in a closed, transparent chamber and measuring the decrease in carbon dioxide concentration as a function of time.

Which color of light will have the fastest rate of photosynthesis?

red light
Blue and red light are most effective for photosynthesis. This is because chlorophyll pigments s absorbs maximum in blue and red regions. Hence there is a higher rate of photosynthesis in these regions.

In which light the rate of photosynthesis is maximum?

In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light. So, the correct answer is, ‘Red light’. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.

How do you calculate the efficiency of photosynthesis?

Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent.

Why did the rate of photosynthesis decrease from 35 to 45?

This changes the shape of the active site for the enzymes, which means that the reactants can no longer fit into the enzyme’s active site, thus resulting in the rate of photosynthesis decreasing. The denaturing temperature depends on the type of plant but is usually around 35-45°C.

What can limit the rate of photosynthesis?

What is net photosynthesis rate?

Net photosynthesis is the carbon fixation rate minus the rate of CO2 loss in respiration. Respiration will be measured in the dark (photosynthesis cannot occur without any light) and net photosynthesis will be measured under two light conditions (respiration and photosynthesis occur at the same time).

How does carbon dioxide affect the rate of photosynthesis?

The uptake of carbon dioxide (depending on the amount) affects the rate of photosynthesis. Also another huge factor in the process of photosynthesis is sunlight. It helps determines on what pigments the plant possess and how much work they can do. Lab Report on Photosynthesis. (2016, Dec 18).

What are the biggest components of photosynthesis?

This lab covers the big components in photosynthesis including carbon dioxide intake, light consumption, and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce.

What is the most important pigment in photosynthesis?

Chlorophyll is a pigment in leaves that reflect green light waves. This is the most important pigment in photosynthesis and there are also accessory pigments used in plants. Also in this lab there is the internal and external anatomy of a typical leaf.

What is photosynthesis and how does it work?

Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of photosynthesis. Sir Isaac Newton was an English physicist that used a light prism and demonstrated how white light contains varying colors.
