Why plant photosynthesize faster in sunny days as compared to cloudy day?

Why plant photosynthesize faster in sunny days as compared to cloudy day?

Rate of photosynthesis depends on the amount of sulight available. On a cloudy day, very little sunlight is available. So the rate of photosynthesis will be very low. On the other hand, a bright sunny day will provide bright sunlight, leading to a high rate of photosynthesis.

Why does temperature affect the rate of photosynthesis?

As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .

How does sunlight affect flowering?

Sunlight also affects the ability of plants to flower. In many plants the duration of the light determines their flowering schedule. Thus, so called “short-day” plants, e.g. chrysanthemums, require long nights before they will flower. Conversely, “long day plants”, e. g. cone flowers, need short nights to flower.

Why does photosynthesis not take place at night?

Photosynthesis doesn’t occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. If there is enough light during the day, then: the rate of photosynthesis is higher than the rate of respiration.

Why is the rate of photosynthesis is higher during the day?

Rate of photosynthesis is higher during the day because of the presence of sunlight , and during the process of photosynthesis plants take in carbon dioxide and give out oxygen. During the night , because of the lack of sunlight photosynthesis does not take place.

Why is the rate of photosynthesis high on clear day?

The rate of photosynthesis is high on a clear day . One of the major requirements for Photosynthesis is sunlight. A cloudy day has little sunlight so the rate is low and a clear day (or a bright day) has high sunlight so the rate of photosynthesis is higher.

What affects rate of photosynthesis?

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

Why the rate of photosynthesis in plants is low both at lower and higher temperatures?

Photosynthesis is an enzymatic process. At low temperature the activity of enzymes is lowered due to which the rate of photosynthesis is also low. Again when the temperature is very high, the activity of enzymes decreases which leads to low rate of photosynthesis.

Why does light increase the rate of photosynthesis?

As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.

What happens if plants get too much sunlight?

A common problem with both indoor and outdoor plants is that they can suffer from too much sun. The sun’s rays can stress a plant’s leaves to the point of dehydration, causing the plant to lose much of its green vigor. Often times, the soil beneath the plant will have little or no moisture, causing it to harden.

Why do photosynthesis occur during day time only?

Photosynthesis in plants occurs only during the day when there is the sunlight but plants respire throughout the day and night. Therefore plants perform photosynthesis only during the day in the presence of sunlight and respiration all day long.

Why does photosynthesis usually stop at night or cold weather?

Answer: In many plants, the mechanical damage due to freezing is the reason why photosynthesis stops at freezing temperatures. The carbon fixation reactions are much more sensitive to low temperature because they are typical enzymatic reactions.

What are the factors that affect the rate of photosynthesis?

Several factors can affect the rate of photosynthesis: light intensity. carbon dioxide concentration. temperature. The amount of chlorophyll also affects the rate of photosynthesis: plants in lighting conditions unfavourable for photosynthesis may synthesise more chlorophyll, to absorb the light required.

What are the different types of photosynthesis in plants?

Not all forms of photosynthesis are created equal, however. There are different types of photosynthesis, including C3 photosynthesis and C4 photosynthesis. C3 photosynthesis is used by the majority of plants. It involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose.

What happens if there is not enough light for photosynthesis?

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.

Which is the optimum temperature for photosynthesis?

The optimum temperature for most plants is 15°C to around 40°C. Temperature affects the rate of photosynthesis in crop plants and affects where certain crops can be grown.
