How Does Sunlight Make Plants Turn Green ???

Sunlight makes plants produce chlorophyll. There is a lot more chlorophyll in plants than carotenoids and anthocyanins, so leaves look green. The chlorophyll is what absorbs sunlight to give the plant the energy it needs to make food out of water and the carbon dioxide in the air. Chlorophyll is hard for a plant to make. A plant only makes it in places where it will do the most good (that is, collect the most sunlight). 

Whats In An Atom ???

What’s in an atom? Mostly nothing. The vast majority of an atom is empty space. To get it into perspective, imagine an atom the size of an international sports stadium. The electrons are right up at the top of the stands, each smaller than a pin-head. The nucleus of the atom is on the centre spot of the pitch, and is about the size of a pea. For many centuries, atoms, which were entirely theoretical, were thought to be the smallest possible units of matter, hence the word, which means ‘not-cut’ in Greek. Then, in 1897, the electron was discovered, followed in 1911 by the nucleus.

What Man-made Artefacts Can Be Seen From The Moon ??

Deduct ten points if you said the Great Wall of China. No human artefacts at all can be seen from the moon with the naked eye.
