Wow, Biology does come in handy! Anyway, certain plants grow new roots because it's a way of asexual reproduction for that plant. Many cacti do this. They drop stems or branches that grow roots and become clones of the original plant.
They have shallow roots that grow right under the water.

They need light to activate photosynthesis and get nutrients. Because they need light to even grow, most plants grow towards the light.
most plant roots grow down, not up!
No, not at all.
They grow extremely long roots.
They have shallow roots that grow right under the water.
Not all plants have roots (eg phytoplankton) and while some plants do grow form their roots (eg grasses), most plants do not grow from their roots but from their apical growing tip.
Some plants grow up and down, the directions being determined by gravity. (stem up, roots down)
The roots of most plants grow towards the pull of gravity.

Mangroves generally grow on the sea shorline. These plants are adapted to amphibian conditions. Their respiratory roots and viviparous fruits are special features to survive and propagate further.

Few plants survive in a desert because the climate is too dry.Because there isn't enough water or moisture in the soil for plants to take up through their roots so normal plants can't survive in the desert.
Plants grow from the roots and seeds germinate in the roots as well.
Orchids, Bromeliads, moss, roots, and wooden vines. Even though there are some plants growing in trees many also grow in the understory and some that grow in the water.
