Why are most of the leaves and stems of plants green when they are young?

The reason why plants are green is because there are many tiny green particles in their leaves, which we call chlorophyll. It is an important type of green pigment in the chloroplasts of plant cells.

The concept and principles of photosynthesis

In the leaves of green plants, there is a substance called chloroplast. Plants use light energy through chloroplasts to synthesize carbon dioxide and water into organic matter that stores energy, and at the same time releases oxygen. This process is called "photosynthesis"

Knowing the "photosynthesis" of plants, do we now know the most important conditions required for plant growth?
