Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Similar effects occur when a light wave travels through a medium with a varying refractive index‚ or a sound wave travels through one with varying acoustic impedance. Diffraction occurs with all waves‚ including sound waves‚ water waves‚ and electromagnetic

light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf include the upper and lower epidermis‚ the

like glucose. Cellular respiration is a process in which O2 is delivered to cells in an organism & metabolic process in cells leads to the production of ATP by the breakdown of organic substances. Cellular respiration occurs in the mitochondrion of the cell and photosynthesis occurs in the chloroplast. There are some similarities between the process involved however their products and reactants are the exact opposite. Photosynthesis can be divided into two stages: Light Reaction & Calvin Cycle. The
