Well, in a way it is true, as, chloroplasts are the reason why plants photosynthesize. So, with the photosynthesis, it releases oxygen, which is the power generator for life on Earth, as we breathe in oxygen.
Xerophytes are plants that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.
Producing plants by vegetative propagation is faster than growing plants from seeds. ... Therefore, farmers prefer the method of vegetative reproduction for growing plants.
