– Why is grass green?
In: Biology
Grass, like other plants, contains Chlorophyll. Chlorophyll is a key piece of photosynthesis (taking in sunlight to convert CO2 and water into glucose and oxygen).
Chlorophyll just happens to be green. Since it is green, it absorbs all sunlight *except* the green light that it is reflecting. Importantly, if plants took in too much sunlight they would be damaged by the excess heat, and if they took in too little, they would not get enough energy.
Because of the depths in the ocean where the organisms producing chlorophyll first evolved, green ended up being the right colour to land on when evolving the capability. Just enough non-green light came through, so by being green it absorbed the right amount.
Plants use light to make food. They absorb the light. The plants are soaking up all the colors except green, and since the green isn’t soaked up, it’s reflected back and that’s the color we see. Some plants like green light and reflect other colors, thats why some plants have red leaves.
The grass has little dots that are green to make it look green and when a plant get sick they turn brown
