Why do plant shoots grow upwards?
Amyloplasts settle at the bottom of the cells of the shoots and roots in response to gravity, causing calcium signaling and the release of indole acetic acid.

Which external stimulus causes a plant to bend toward it?
phototropism
Will bulbs grow if they are planted upside down?
Most bulbs have a flattened basal plate (basal meaning bottom) from which roots grow and a pointed side from which stems grow, so it makes sense to plant them with the flat end down and the pointed end facing up. But … if you plant them sideways or upside down, they’ll still grow perfectly well.
What happens if you plant bulbs too deep?

Will garlic grow if planted upside down?

The result is likely to be very small garlic plants that fail to mature into multiple cloves.
Do beets need a lot of sun to grow?
Exposure – Beet seeds need full sun and cool temperatures to thrive. Beets are a cool season crop and planted in spring and fall. Full sun is considered to be 6 hours plus of UV light. This means even if it is cloudy, on a clear day that area of your garden would be in full sun for 6 or more hours.
