well usually you need something stronger then a magnifying glass, but it increases the heat from the sun and burns something in its radius
Have you ever wondered how a magnifying glass is constructed? A magnifying glass is constructed by using a convex lens to curve and magnify objects. A magnifying glass is also constructed out of glass.
Microscope? Magnifying Glass?

It depends on the color, so i can't answer that.
My cousin and I used a magnifying glass to see the paper.
With a magnifying glass
A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.
When you place a magnifying glass over an ant and the sun is out, the light from the sun hits the convex glass and becomes concentrated at a certain point. That point will eventually become hot enough to burn the ant.
A big magnifying glass will burn the US, one neighborhood at a time.
The lens of the magnifying glass concentrates the sun's light to a point. At that point the paper is heated to its ignition temperature and it can catch fire
It's quite easy- take a magnifying glass and a dry piece of a paper ( preferably newspaper ) and go to a place where appropriate sunlight is available. Let the light of sun fall on to the magnifying glass. Bring the piece of paper beneath the magnifying glass. Now your objective is to move the magnifying glass up and down in such a way that the light emerging from the magnifying glass concentrates to a point. Hold the both things in the same position for a while, and soon you will be able to see the miracle, fire without a matchstick ! Enjoy!

If you mean to ask how a magnifying glass can use sunlight to burn a plant, then here's how.A magnifying glass focuses the light going through it so that it all converges into a single point (focal point). The light that would have otherwise been spread out over the area of the magnifying glass is "concentrated". Therefore there is much more energy hitting that one point than otherwise would be. The light raises the temperature of the plant to the point where it will burn.
Magnifying glass or cook it maybe, or just try to burn it in someway.
