The gravity will hold water in the pool however the lack of humidity in the atmosphere would probably cause the water to evaporate very rapidly. Plants would have problems as well with this not to mention a requirement for an atmosphere that is composed of the gases they need for them to grow.
what happens when a plant does not have enough water?
Plants grow and develop when given enough sunlight and water. Plants absorb light energy, drink water, undergo photosynthesis, and grow with the food that they have created for themselves.
To absorb enough sunlight.
Plants don't have minds... they just grow wherever they can. If there's enough food, water, and sunlight for a plant to grow in a rock, it will.

The roots of most plants grow towards the pull of gravity.
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a Biology teacher. this is bullcrap it is fake
They wouldn't
Geotropism, the tendency of some plants to grow straight up, against the force of gravity.
Maybe they don't have water or enough sunlight or the right soil.
A desert.
Just enough to achieve sprouting of seed
