Black, obviously. The reason green leaves appear green is because when placed in white light, the leaf absorbs all the colors of the spectrum and reflects only green light. However, in red light, the leaf absorbs the red light but is unable to reflect any green light because there is no green to reflect. So, it appears black.
Try watching green plants at night (or very low light conditions). That should give you a practical proof of the fact mentioned above.

What color does a green leaf appear to be in red light and why?
It appears black. A green pigment can only reflect green light and red light is a primary colour, that is it contains only red.
If A green leaf placed in a dark room is illuminated by red light the leaf will appear to be?
black
Leaves appear green because the green protion of the light that strikes them is what?
Reflected. The other colors of the light spectrum are absorbed. In fact, this is how all 'color' works - whatever the object. A red ball, a white shirt, etc. The color you see is the color being reflected back at your eyes, while the other colors are absorbed by the object.
What colors do your eyes respond to when you look at a green leaf?
Violet, blue, and red are the colors your eye responds to most when looking at a green leaf.
What is the real color of light?
They have pigments which absorb all wavelengths except green, so that's the colour frequency that reaches the eye. Without those pigments, they're mostly transparent under a microscope, with the denser cellular wall being darker. A leaf with no chlorophyll would probably be opaque, since it light wouldn't cross it as easily as it does glass because of its molecular structure at the molecular level. mostly have green colors but in differnt plant color varies
What make a leaf appear green?
presence of Chlorophyll in the cells of leaf reflects the green spectrum of light hence the leaf appear green.
Why does leaf appear green?
it reflects green light
What color does a green leaf appear to be in red light and why?

What color does a green leaf appear to be in a red light Why?
It appears black. A green pigment can only reflect green light and red light is a primary colour, that is it contains only red.
Why does a green leaf appear black with a red light?
The leaf 's color and the red light mixes with each other and reflects on the eyes of the person seeing the leaf. The wavelength is also sorter so the color turns black
A green leaf placed in a dark room is illuminated by red light The leaf will appear?
No
Is the color of a leaf light relfected or light absorbed?
White light form the sun is made up of :-Red, Orange, Yellow, Green, Blue, Indigo and Violet colored light (as you see in a rainbow)When this white light hits a leaf, all the colors exceptGreen are absorbed by the pigments in the leaf. The Green light is not absorbed and this is reflected to your eyes so that leaves appear green.
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.
Why does a leaf appear green?
because it contains a green pigment called chlorophyll
If A green leaf placed in a dark room is illuminated by red light the leaf will appear to be?
black
Why leaves appear green in photosynthesis?
The pigment responsible for photosynthesis (Chlorophyll) reflects the green wave length of sunlight when light fall on the leaf. That is why leaves appear green in the presence of light.
If orange and yellow pigments are present in a leaf why does the leaf appear green in color?
Because there are much more chlorophyll which make them green than green and orange pigments.
