Cress and grass
YOU WILL NEED
Small patch of living grass sod
Scissors
After you cut the tops off, the grass grows back and it will soon look
the way it did before you cut it, while the cress does not grow back.
That is because of the so-called growth point of the plant. The growth
point is the point at which the plant starts to grow. With grass, this point
lies just above the ground. Even when you cut the grass, the growth point
is not removed, and the grass can grow back. The cress growth point lies
much higher, right under the green top. So if it gets cut off, the cress
can’t grow anymore.
