Explain how plants are adapted to conditions: arid climate, excessive moisture, lack of light, excessive light

Arid climate – the area of leaves and their pubescence, the film on the surface of leaves of large thickness are greatly reduced.
Excessive moisture – the root system is well developed, the leaves have a different shape.
Lack of light – leaves turn dark green and grow, the stem stretches, flowering stops (in many plants).
Excessive illumination – the color of the leaves is yellow-green, growth slows down, resulting in more squat with short internodes and wide short leaves.
