Just fine ... ambient pressure has little effect on plants.
The cell wall isolates them well.

Not many plants grow under casuarinas because of the needles. Plants dont have to grow everywhere, Apart from human cleared areas casuarina needles create some of the few gaps in the forest for animals to hang out in. I could tell you which species grow naturally under them in my area. But they may not be endemic to your area. There are a number of invasive weeds that are able to grow under Casuarinas. These are terrible plants and I certainly dont want people to grow them. Ehrharta erecta, Cyperus, Bidens pilosa. Plants can grow from runners or suckers in Casuarina needles also. An example of a tree that can grow by suckering through Casuarina needles is the Casuarina. =] . Go out and see what grows under them naturally in your area, and if you are going to grow some yourself insure that they are provenant to your area. read - What is provenant? I only propagate endemic provenant indigenous plants. I dislike people who treat plants like toys. "OW Look isn't that JESSAMINE pretty , I'm going to plant it everywhere because I'm an *&^%$#@". Know what I mean?
African Violets . . . . . . .Streptocarpus . . . . . Begonia . . . . . . Kataka-taka
Fluorescent light works for most of plants and even aquarium fish. But when it comes to special races of plants, such as mariguana or some philotherms, HPS or MH can achieve a better effect. Check the link below for more detail about fluorescent light.
The roots of most plants grow towards the pull of gravity.
Plants use water and dissolved minerals from the soil but the majority of the organic material comes from the carbon they fix by photosynthesis from atmospheric CO2
Yes, high pressure sodium lights will help to grow plants indoors. You can grow tomatos and other plants that need normally need sunlight.
No
yes
Their roots grow and expand to create pressure that wedges rocks apart.

Sunlight
The atmospheric conditions , soil determines what type of plant is grown. The intensity of rainfall is also considered.
put a seed under ground then water
