Plant

• The worm at the bottom will take 60 seconds to reach the second layer. And for each minutes, there will be a new leaf. When there are 60 leaves in the second layer, the flower will grow one petal. The flower at the left side represents daytime (a.m.), and the one at the right represents nighttime(p.m.).

Step:

1. Draw a worm, flower, and a small tree
2. Duplicate these
3. Make pm/am flower different
4. Make variables (second) forrising worm, (minute) for small tree leaf, and (hour) for flower petals
