Fotosynthesis in 2 steps: from the anorganic elements H2O and CO2 (water and carbondioxide) the chloroplasts in a plant build organic matter via the energy of the sun. In the first step ATP (adenosine triphosphate) and NADPH2 are created; in a second step this ATP is used to free energy (->ADP+P+energy) to create glucose (C6H12O6) en oxygen (6O2). It’s a balance of anabolic and catabolic reactions – the (anorganic) fluids go up (water, minerals) and the organic matter (glucose, starch) goes down to the roots of the plant where it is used for its growth or stored as future nutrients.
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction (oxidation of one molecule and the reduction of another). Respiration is one of the key ways a cell gains useful energy to fuel cellular changes. The cellular respiration process takes place in the mitochondria.
Some pdf’s as an introduction to the world of biology:

Diffusion is a non-energy consuming proces between 2 substances. In the picture above, 300 gr sugar is diluted in 750 ml vodka. The proces takes place in a bottle containing an orange with 40 incisions (in which 40 coffeebeans are stuck). Leave the set-up for 40 days (christian) or for 21 days (pagan). The result should be a delicious drink for the upcoming holidays. Cheers!
