What are the 3 things that can happen to light which strikes a leaf?
When light strikes a leaf, it can be absorbed, transmitted through the leaf, or reflected off the surface. Absorbed light is used in photosynthesis to produce energy for the plant. Transmitted light passes through the leaf to reach other parts of the plant, while reflected light bounces off the leaf's surface and can be used for other purposes.
What happens to light energy when it strikes what happens to light energy when it strikes a leaf?
When light energy strikes a leaf, some of it is absorbed by pigments in the leaf for photosynthesis, some is reflected, and some is transmitted through the leaf. The absorbed light energy is converted into chemical energy by the leaf for use in metabolic processes.
Describe what happens when light strikes a green leaf?
When light strikes a green leaf, the leaf absorbs red and blue wavelengths of light while reflecting green wavelengths. The absorbed light is used in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen, which the plant uses for energy and growth. The green pigment chlorophyll in the leaf is responsible for absorbing the light and carrying out photosynthesis.
What happens to green light an red light when they shine on a green leaf?
When green light shines on a green leaf, the leaf absorbs most of the green light and reflects some of it, giving the leaf its green color. Red light is not absorbed as efficiently by the leaf, so it gets reflected, making the leaf appear green under white light.
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.

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.
What happens when light strikes a green leaf?
the leaf reflects on the light so it prevents it to burn (fire)
When light strikes a green leaf all the colors except green are reflected?
sex
When the light strikes a green leaf all the colors except green are reflected?
sex
Describe what happens when light strikes a green leaf?
When light strikes a green leaf, the leaf absorbs red and blue wavelengths of light while reflecting green wavelengths. The absorbed light is used in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen, which the plant uses for energy and growth. The green pigment chlorophyll in the leaf is responsible for absorbing the light and carrying out photosynthesis.
When light strikes a green leaf how does this explain why leaves appear green?
Leaves appear green because they contain a pigment called chlorophyll, which absorbs red and blue light but reflects green light. When white light strikes a green leaf, the chlorophyll absorbs all colors except green, which is why we see the leaf as green.
What happens to sun light that strikes a leaf but is not trap by the chlorophyll?
It is either transmitted or reflected. Often, different portions of the light do both.
Why is it that not all the light that strikes the leaves of a plant is stored as chemical energy?
Not all the light that strikes the leaves of a plant can be stored as chemical energy because some of it is reflected, some is transmitted through the leaf, and some is not absorbed by the photosynthetic pigments in the chloroplasts. This unabsorbed light is not converted into chemical energy through photosynthesis and is either lost as heat or reflected back.
What happens to green light an red light when they shine on a green leaf?
When green light shines on a green leaf, the leaf absorbs most of the green light and reflects some of it, giving the leaf its green color. Red light is not absorbed as efficiently by the leaf, so it gets reflected, making the leaf appear green under white light.
What part of a leaf does light strike for photosynthesis to begin?
pigment molecules absorb light energy
