Because trees go through photosynthesis that's a process where trees have these pigments called chlorophyll ( that are colored green) that absorb the green spectrum of light and converts the energy absorbed by the light in combination with CO2 into oxygen and starch ( stored in their bodies for food). The trees are full of chlorophyll therefore they are green and not blue.

It's not advantageous enough for trees to be blue, I'd guess.
Here in California, we have trees with blue-gray leaves (eucalyptus, from Australia). We have trees that have purple leaves.
As far as chlorophyll goes, it's one of several pigmented substances in plants, which is why you can find plants with gray leaves, purple leaves, etc.

you got me thinking - for a 10 year olds homework? wow
it because they wouldnt match the grass
na, something to do with chlorophyll needing to absorb green light to convert carbon dioxide and water in to sugar and oxygen - photosynthesis

Chlorophyll is a green colored substance in the leaf of the plant that turns carbon dioxide into oxygen.
