How does light intensity affect oxygen production in photosynthesis?

How does light intensity affect oxygen production in photosynthesis?

Oxygen production increased as the light intensity increased due the greater availability of light energy for photosynthesis.

What effect does light intensity have on plants?

Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

Why is light intensity important for plant growth?

Light intensity can affect plant metabolism rates. Photosynthesis enables plant metabolism processes to take place and provides the energy that fuels these processes. Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant’s ability to grow.

What will happen to a plant if light intensity is reduced?

Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply.

What is the relationship between light intensity and oxygen production?

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.

How does light Colour affect oxygen production?

I got these results because one molecule affected most by photosynthesis, chlorophyll, produces the most oxygen under blue and red light, while reflecting green light. After 24 hours, the white light produced the most oxygen, followed by the blue, red, yellow and green light, respectively.

How does color light affect plant growth?

The color of light DOES affect plant growth, but the effect is more noticeable under low light intensity. Red & blue light are most effective for plant growth, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.

Does increasing light intensity always have the same effect on oxygen production?

Overall, we observed an increasing rate of oxygen production with increasing light intensity. Increasing light causes an increase in the photosynthetic rate most likely due to light’s stimulatory effect on Photosystem II of C. reinhardtii.

When the light intensity is zero the rate of oxygen production is?

compensation point for light
The light intensity at which the net amount of oxygen produced is exactly zero, is called the compensation point for light. At this point the consumption of oxygen by the plant due to cellular respiration is equal to the rate at which oxygen is produced by photosynthesis.

What light produces most oxygen?

Conclusion. I got these results because one molecule affected most by photosynthesis, chlorophyll, produces the most oxygen under blue and red light, while reflecting green light. White has all the colors of the visible spectrum.

How does light intensity affect the growth of a plant?

Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant’s ability to grow. Plant growth processes involve the use of light, carbon dioxide and water to manufacture food for the plant’s use, according to the Texas A&M University Agricultural Extension Service.

How does light affect the rate of photosynthesis?

Photosynthesis enables plant metabolism processes to take place and provides the energy that fuels these processes. Light intensity levels can have a significant effect on photosynthesis rates, which are directly related to a plant’s ability to grow.

What happens when there is too much light in a plant?

With too little light, photosynthesis cannot occur either and the plant suffers without the production of sugars. There are many complicating interactions between plants and light. I hope that you continue to investigate this as the story gets more interesting and exciting the deeper you go.

How does light affect the production of gas?

The fact that no gas was produced while the setup was kept in the dark showed that light was the cause of the production of oxygen. The increases in bubbling (gas production) as the light source is moved closer to the plants indicate that the rate of oxygen production by the photosynthesis is affected by the intensity of the light source.
