Do plants photosynthesize only in the light?

Just like humans and animals, plants need energy to survive and thrive, and they make their food themselves via a process called photosynthesis, which occurs only in the presence of light.

Does photosynthesis and respiration occur both light when dark?

Though it is true the light reactions can only occur when the sun is out, cellular respiration occurs continuously in plants, not just at night.

Which process in photosynthesis is most directly driven by light energy?

Which process is most directly driven by light energy? The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Does photosynthesis mean made by light?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

In which light photosynthesis takes place faster?

As far as the rate of photosynthesis is concerned, it is fastest in white light making the rate of photosynthesis maximum. After white, we have violet light where photosynthesis occur to a higher extent as it has the shortest wavelength hence has the max energy.

Can plants photosynthesize at night?

It is well known that plants photosynthesise in the presence of sunlight, consuming carbon dioxide, water and energy, and producing glucose and oxygen. At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen.

Which light produces the healthiest plant?

The effect of Full spectrum (white) light on plant growth Very healthy growth. Good flower production, dense growth, high productivity and yield. The Full Spectrum light was also great for the flowering plants and had similar quality of flowers and leaves to the Red light grow.

What process is most driven by light energy?

Photosynthesis
Photosynthesis: Photosynthesis is the process by which the chlorophyll molecules convert the light energy into chemical energy where there is the fixation of inorganic carbon into organic carbon with the help of light and provides food for the ecosystem.

Which of these carries the most energy?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

What is the relationship between water light and CO2 and photosynthesis?

Light provides the energy for photosynthetic pigments to convert carbon dioxide (CO2) and water into sugars and oxygen. As light intensity increases Ð until a point Ð the amount of sugars increases and thus, more energy is available for plant growth and maintenance.

Which light takes place photosynthesis?

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays. The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis.

Which is correct about photosynthesis and respiration in plants?

Thinking about photosynthesis and respiration in plants, which statement is correct: (tick one answer) 8. Light energy captured by photosynthesis is used in a plant for the synthesis of: (tick one answer) 9. The gas evolved in bubbling pond weed in the light is: (tick one answer)

How are blue and red light used in photosynthesis?

It is important to note first that all visible colours of the spectrum are used by plants, but for now, we will focus on blue and red light and what can be achieved with their use. For the two photosystems I & II, chlorophylls a & b exist to assist the photosynthetic process by absorbing specific spectra of light energy.

How does chlorophyll help in the photosynthesis process?

For the two photosystems I & II, chlorophylls a & b exist to assist the photosynthetic process by absorbing specific spectra of light energy. Chlorophyll a absorbs the violet blue – blue wavelengths of light (390-450nm with peak at 420nm) and orange to far-red (600-700nm with a peak at 680nm).

How are green and yellow photons used in photosynthesis?

Plants still use the green and yellow spectra as there exist photopigments that turn green or yellow photons (500-600nm wavelengths) into blue and red photons through excitation and emittance reactions. Blue light is of course a main contributor to photosynthesis via chlorophyll, but it also influences a plant in other ways.
