What is the best light intensity for photosynthesis in Lux?
LIGHT INTENSITY If the level of light is less, growth is reduced. In chrysanthemums, a light level of 4000 lux is just enough for the rate of photosynthesis to equal the rate of respiration. This is called the light compensation point.
What is the relationship between distance of light intensity of light and photosynthetic rate?
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 is the rate of photosynthesis related to light intensity?
The rate of photosynthesis is directly proportional to the light intensity until another factor becomes limiting. At very high light intensities, photosynthesis is slowed, but these light intensities do not occur in nature.
How much Lux do plants need for photosynthesis?
From sunlight (at least 6 hours a day): High-light or full-sun plants need at least 60,000 lux. Medium-light or partial sun plants need at least 35,000 lux. Low light or partial shade plants need at least 15,000 lux.
Is 500 lux enough for plants?
500-1,000 LUX: Still low light intensity but bright enough to read. It resembles natural light of an ordinary room. This light intensity is appropriate for shade-loving plants.
How much Lux do I need in the morning?
The answer here is clear cut: 10,000 lux for 30 minutes is the standard prescription for post-awakening light therapy. This is typically for treating seasonal depression shortly after waking up in the morning.
Why does light intensity decrease with distance?
There is an inverse relationship between distance and light intensity – as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, light energy becomes spread over a wider area.
How are luminosity and intensity related?
It helps to give different names to these two ways of measuring intensity. The total amount of light a source emits is called its luminosity. A light-bulb’s luminosity is roughly proportional to the number of watts it consumes. Brightness is amount of light per unit area.
How does light intensity affect photosynthesis BBC Bitesize?
Light intensity 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 optimal best temperature for photosynthesis?
At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results.
How many Lux are in Monstera?

| Norfolk Island Pine | 400 FC | 5000-6000 FC |
| Parlour Palm (Chamaedorea) | 400 FC | 1500-3000 FC |
| Peace Lily (Spathiphyllum) | 200 FC | 1500-2500 FC |
What is the relationship between light intensity and photosynthesis?
The relationship between light intensity and photosynthetic rate is that if the intensity of the light is high then the rate of photosynthesis will increase. However the rate of photosynthesis will only increase to an extent after intensity of light reaches a certain point photosynthesis rate will stay still.
When does the rate of photosynthesis increase or decrease?
However the rate of photosynthesis will only increase to an extent after intensity of light reaches a certain point photosynthesis rate will stay still. Q: What is the relationship between light intensity and photosynthetic rate?
What happens if the light intensity of a plant is too low?
This point marks the minimum light intensity a plant requires to maintain itself and stay alive. If a plant receives light that is lower than the light compensation point, it may no longer be able to undergo photosynthesis and will eventually die.
How is the saturation point related to photosynthesis?
The saturation point is essentially the upper bookend for light intensity – light intensity higher than the saturation point does not increase the rate of photosynthesis. The lower bookend of light intensity is called the light compensation point. This point marks the minimum light intensity a plant requires to maintain itself and stay alive.
