What else can I help you with?
Is it true or false that only portions of visible light can be taken up by chlorophyll?
True, obviously the green part of the spectrum is not used which is why chlorophyll looks green when illuminated with white light.
What 2 things are made when light strikes chlorophyll?
it makes oxygen + glucose.
What is the green pigment that traps light?
Chlorophyll is the green pigment in plants that traps light energy for photosynthesis.
Why is variegated leaf used to test to see if chlorophyll is necessary for photosynthesis?
Variegated leaves have patches of green and white due to uneven distribution of chlorophyll. If a variegated leaf is tested by covering the green parts and exposing only the white parts to light, no photosynthesis occurs in the white areas since they lack chlorophyll. This demonstrates that chlorophyll is indeed necessary for photosynthesis to take place.
The light reflected most by chlorophyll is?
The light reflected most by chlorophyll is green light. Chlorophyll absorbs red and blue light for photosynthesis, but reflects green light, giving plants their green color.
Why chlorophyll is green in colour although it absorbs in blue and red region?
Light is white. White is a neutral color that is an equal mix of all the primary colors. Plants are green because they have green chlorophyll. The reason why chlorophyll is green is because when white light emitted by the sun hits a green plant the chlorophyll absorbs the red and blue light but doesn't absorb the green light so the green light bounces off the plant and goes into our eyes making the "plant look green". It is rather more complex to why the chlorophyll doesn't absorb green light and only absorbs red and blue light.
Is it true or false that only portions of visible light can be taken up by chlorophyll?
True, obviously the green part of the spectrum is not used which is why chlorophyll looks green when illuminated with white light.
What does light do to Chlorophyll?
The light is absorbed by the chlorophyll. The light is then used to excite electrons.
How does light energize a chlorophyll a molecule?
Light is absorbed by the chlorophyll.
Why does a leaf look green?
Because of Chlorophyll (it is a green pigment). There are two types of chlorophyll in plants and algae. Both chlorophylls absorb green light (from the spectrum of light) poorly. So when white light shines on structures like leaves (which have chlorophyll), green light is transmitted and reflected and the structures appear green.
What 2 things are made when light strikes chlorophyll?
it makes oxygen + glucose.
What is the green pigment that traps light?
Chlorophyll is the green pigment in plants that traps light energy for photosynthesis.
What stalked vegetable is made white by growing it underground so that it can't produce chlorophyll?
Asparagus
What happens when a chlorophyll a molecule produce light reaction?
Light reaction is not produced by chlorophyll .
When light strikes a green leaf how does this explain why leaves appear green?
Light that is white contains all the colours. When the light hits the leaf, it absorbs all the colours apart from the green light which is reflected back out to your eyes. So you see the leaf as green.
