Note the readings in different temperatures. However, on chara these leaf-like structures are thicker, making microscopic observation more difficult.

During this process, they convert the light energy in sunlight to chemical energy. The photosynthetic process can be divided into oxygenic and anoxygenic photosynthesis based on if oxygen is generated or not. Oxygenic photosynthesis is the most common type and is in class essay writing rubric in plants, algae and cyanobacteria. Anoxygenic photosynthesis is mostly seen in purple bacteria.
