Newton’s first law had to do with inertia, which is a property that explains that something in motion will continue in motion unless stopped by a force of some sort.
“An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”
Photo means light and synthesis means formation. It is a process of formation of food in the presence of light.
It takes place in green plants because they contain chlorophyll and chlorophyll is one of the vital reactant required for this process.
The light gets trapped in the leaf and process the formation of glucose.
Leaf is where photosynthesis takes place. When glucose is formed in leaf, it is transported to other parts of the plants with the help of the vascular bundles.
Plants need energy from the sun, water from the soil, and carbon from the air. The plant uses the carbon to form the leaves and stem and roots. I can go more into detail in the comments if you need.
Can’t see diagram. Could you attach the photo.
