pigment molecules absorb light energy
What else can I help you with?
What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out?
The purpose of keeping the leaf in the dark is to prevent photosynthesis from happening. By covering it with a cardboard cut-out with a specific design, you can control which parts of the leaf are exposed to light, allowing for experiments on the effects of light on photosynthesis in different areas of the leaf.
What form of energy is taken by the leaf during photosynthesis?
The main form of energy taken by the leaf during photosynthesis is light energy from the sun. This energy is captured by pigments in the chloroplasts of the leaf, such as chlorophyll, and converted into chemical energy in the form of glucose.
Will photosynthesis take place in foil covered leaf?
no because the leaves or anyother part of the plan has to be exposed to the sun so the energy from the light will hit the plant and it can crreate sugar to supply energy (with carbon dioxide as well)
Do any leaf disk float in the dark treatment during photosynthesis?
In a dark treatment, leaf disks do not float because photosynthesis cannot occur without light. During photosynthesis, chlorophyll in the leaf disks captures light energy, producing oxygen and causing the disks to become buoyant. In the absence of light, the disks do not produce oxygen, leading to them remaining submerged. Thus, leaf disks will not float in the dark treatment.
The leaf surface area is just as if not more important than the intensity of light in photosynthesis?
The leaf surface area is indeed crucial for photosynthesis because it provides a larger area for light absorption and gas exchange. While light intensity is also important, having a sufficient leaf surface area allows for more efficient utilization of available light for photosynthesis. Ultimately, both factors must work together to maximize the process of photosynthesis.
Which part of a plant does photosynthesis begin?
It begins in the leaf, in the chloroplast.
What happens to sunlight that strike a leaf but is not trapped by photosynthesis?
The sunlight that strikes a leaf but is not trapped by photosynthesis is reflected back by the leaf. Only certain wavelengths of solar energy is absorbed by a leaf.
The leaf of a flower?
the leaf uses the sun light to power the chloroplast to do photosynthesis
When light energy from the Sun strikes a leaf how is the energy conserved?
When light energy strikes a leaf then chlorophill (a) present in leaf absorb that light energy . By use of that energy photosynthesis occurs.
Why is the leaf held at a right angle to the light source?
The leaf is held at a right angle to the light source to maximize the surface area exposed to sunlight for photosynthesis. This position ensures that the chloroplasts in the leaf receive optimal light energy for the process of photosynthesis to occur efficiently.

What are two things that happen to light when it strikes a leaf?
Light is either absorbed or reflected when it strikes a leaf. Absorbed light is converted into chemical energy through the process of photosynthesis, while reflected light is what gives the leaf its color.

no because the leaves or anyother part of the plan has to be exposed to the sun so the energy from the light will hit the plant and it can crreate sugar to supply energy (with carbon dioxide as well)

Sunlight arrives at the leaf for photosynthesis in particles of light energy called what?
photons
