chorophyll
Most photosynthesis occurs in a portion of the leaf called the palisade mesophyll. Palisade cells contain chloroplasts, which convert the energy stored in photons to chemical energy through photosynthesis.
The main form of energy taken by the leaf during photosynthesis is light energy from the sun. This energy is captured by pigments in the chloroplasts of the leaf, such as chlorophyll, and converted into chemical energy in the form of glucose.
chemical
The energy transfers that take place in a leaf is light energy into chemical energy (the glucose), or more commonly refered to as osmosis
A leaf does not remove oxygen; rather, it produces oxygen through the process of photosynthesis. During photosynthesis, plants use carbon dioxide and water to create oxygen and glucose, which is a form of stored energy.
oxygen
It's called Chlorophyll, it makes the leaf green and helps with photosynthesis.
Photosynthesis makes a leaf green so when it turns brown it has stopped doing photosynthesis so most likely it is chemical change. Helpful enough? :|
Oxygen is the gas released during the process of photosynthesis.
in the leaf
The chemical energy produced during photosynthesis is in the form of glucose. This molecule stores the energy captured from sunlight by plants, which can be used for various cellular processes.
During the process of photosynthesis, the sugar produced in the leaf (glucose) is converted to sucrose and then transported out of the leaf via the phloem tissue. The sugar is translocated to other parts of the plant where it is used for energy or stored for later use.
