Plant Gravitropism
Plant Gravitropism Alexander Mak
Objective:
To find out whether plants are affected by growing upsidedown.
The purpose of this experiment is to learn whether plants are still able to grow normally if they are turned upsidedown.
Experimenting plant gravitropism, by growing plants upside down.

Seeds
Containers
Covers for the containers
A wooden frame the same width as the containers (so the containers can be balanced upsidedown over it).
Potting soil
Water
Results:
The roots grew down toward the ground even though the plant was upside down. Why?
Gravity affects everything on earth. Even when you turn plants upside down, gravity doesn't let up. Roots will turn and twist to grow toward the ground, following gravity's stubborn tug.
Plants are photosensitive, plant’s direct their stem growth toward the strongest source of light and directs their roots to grow away from the light. I also believe that plants cells are sensitive to gravity as well, so I'm not sure if that have would caused the roots and stem to grow downwards.
Plants are designed to grow with their roots in the ground and their stems pointing up towards the sun. This makes logical sense for a plant because they require sunlight to hit their leaves in order to photosynthesize.
Growing towards the sun ensures that plants will receive the light they need.
Nowadays, upsidedown planters have become popular in home gardens.
Tomatoes are usually planted in these upsidedown containers, which allow the home gardener easy access to their crop. Growing plants upsidedown may affect their ability to produce vegetables, however, as the plant must
invest a lot of extra energy in righting itself and determining the direction of the sun.
