Building a Photosynthetic Human
Light energy would be converted to stored energy and would be captured through the processed called photosynthesis. Plants use photosynthesis which is process green plants and other organisms containing chlorophyll use to capture energy from the sun and transform it into a form that humans and other animals can use to carry out life processes. The constant recycling process of plants consuming carbon dioxide and producing the oxygen we breathe prevents the “green house” effect and the Earth from overheating. Without the process of plants capturing energy from the sun, we would run out of usable energy. Photosynthetic humans would have green skin and they would never lose their color. To increase the surface to volume ratio, these green "people" need to evolve to a more pancake shape.
Photosynthesis
6 CO2 + 12 H2O + sunlight [solar energy] C6H12O6 + 6 H2O + 6 O2
Plant vacuoles which are fluid-filled organelles are required for photosynthesis. Vacuole fusion supports stomatal movements. Vacuole enables gas exchange and allows plants to react to the changing environment.

Cell Structure
We are all composed of them, and that is cells. Cells play a HUGE role in our bodies. They are the building blocks of our bodies. In order for a cell to function it contains many different components that perform specific functions in order to keep the cell running smoothly. The outer part of a cell is surrounded by a cell membrane. The function of the cell membrane is to protect the cell and transport or export nutrients in or out of the cell. Then there comes the nucleus lies in the middle. The nucleus stores DNA and replicates it and then turns it into RNA. Another feature of the cell is the chromosomes, which lie in the nucleus. The chromosomes help to build protein. In addition chromosomes are a single piece of DNA, that's big. Another component that’s in the nucleus is the nucleolus and it builds ribosome’s. Surrounding the nucleus lays the endoplasmic reticulum. It is divided into rough and smooth endoplasmic reticulum. The rough endoplasmic reticulum is the starting stage of proteins. The smooth endoplasmic mains function is to synthesize lipids. All around lies things called ribosome’s which are stuck to the rough endoplasmic reticulum and make proteins. They have a very important function as well. They digest food for the cell. The mitochondrion supplies energy to the cell, very important function! The cell also has a feature call golgi apparatus, and its job is to distribute and ship the cells chemical products. Lastly there comes vacuoles and their main job is to store the cells chemical components. All these features of the cell are incased in the cells cytoplasm which is gel like. This is the cell structure broken down into main parts but in a way I hope you can make sense of.
