Some tiny parts are special: when you look at them in a blue light, they don’t look blue but instead green or red. They take the heat that is in the blue light, keep some for themselves and then send turn the rest of the heat into green or red light. They do that always in the same way and people who figure things out can use this in many different ways.
One tiny part that changes the light is the one that is important for taking light from the sun and making sweet stuff from it in green living things. People look at it to learn more about the way the sweet stuff is made. They put blue light on the part and count how much red light is sent back. Then, they can count how much sun light is taken up in the green living thing.
Another tiny part that changes light can be put into living things to follow what is going on. With very strong glasses people can look at the tiny water bags and put blue light on them. The tiny parts then sent back red light from where they are and people can understand what they do.
Can you guess what we are describing?
*In which we use Randall Munroe’s ‘simple writer‘ to explain plant-and-pipette topics. Can you guess what they are?
Monroe’s ‘simple writer’ limits language use to only the 10 hundred most common words in the English language. So the word ‘chloroplast’ is out. But so is ‘duck’, ‘cuddle’, and ‘explosion’.
We’ve tried to define a plant and pipette related word using only these common words. Can you tell what we’re talking about? The solution is shown at the bottom.
