Photosynthesis is one of the most important processes in this universe. Plants are known as autotrophs, meaning that they make their own food (Urry et al. 155). They make their own food by going through the process of photosynthesis. If photosynthesis does not occur, then the plants will not survive. Heterotrophs, organisms that do not make their own food, need plants for food in order to provide energy for the organelles in their cells (Urry et al. 155). Without photosynthesis, autotrophs will not survive, and without plants, heterotrophs will not survive. In order for photosynthesis to make food, the plant must go through a complicated process to provide the energy it needs to drive the functions of its organelles.
The complete equation for photosynthesis is:
6CO2 + 12H2O + Light Energy C6H12O6 + 6CO2 + 6H2O (Urry et al. 157). Carbon dioxide gains electrons and is reduced to glucose. Water loses electrons and is oxidized into oxygen (Urry et al. 158). The process of photosynthesis mainly occurs in the chloroplasts of the mesophyll cells in the leaf (Urry et al. 156). The chloroplast contains an inner and outer membrane. The intermembrane space is between the inner and outer membranes. The inner membrane is filled with a fluid called stroma. In the stroma are ribosomes, chloroplast DNA, and thylakoids. A thylakoid is a flattened membranous sack. Each flattened sack of a thylakoid is known as a granum, and a sack of sacks is known as a grana. Chlorophyll is…
