No, plants do not always grow downward. Plant roots always grow downward due to positive gravitropism or positive geotropism. Plant shoots always grow upwards due to negative gravitropism or negative geotropism.

They grow towards the light!
They grow down from trees. ----They actually grow pointing upwards
I know buds grow into shoots.
Positive gravitropism in a plant's shoots ensures that they grow upwards, toward light, which is essential for photosynthesis. This upward growth helps maximize the plant's exposure to sunlight, enhancing its ability to produce energy and nutrients. Additionally, by growing away from the soil, shoots can access better air circulation, which is crucial for gas exchange. Overall, positive gravitropism supports the plant's survival and growth in its environment.
Nope - they grow upwards from the ground.
Because they like to be stepped on!
