The Process of Photosynthesis in Plants: An Overview

By examining the chemical reactions that allow plants to absorb and use light energy, we can improve our understanding of the ways that humans have both accidentally and intentionally manipulated natural plants to affect the photosynthetic pathway and production of the food we eat.

Although light energy is frequently written as a in the overall reaction for photosynthesis, energy is not an actual reactant molecule. Light energy is written on the reactant side to indicate that this energy is needed for photosynthesis to proceed. Energy-wise, the overall reaction of photosynthesis is because the reactants contain less potential energy than the .

Photosynthesis: Overview - YouTube

The net chemical reaction of photosynthesis captures sunlight energy to carbon dioxide by adding electrons and hydrogen to form glucose. Because electrons are added to the carbon molecules, new electrons are taken from water to replenish the system. Therefore, water is , producing oxygen gas. To balance this chemical equation, six molecules of carbon dioxide (CO2) are reduced to produce one molecule of glucose (C6H12O6).

This online activity provides both an overview and in-depth look at the key players and events in photosynthesis.

Inside each chloroplast, the thylakoid membrane is extensively folded into a series of flattened sacs called . Because the thylakoid membrane is continuous, the thylakoid sacs are layered into rows and rows of stacks. Each stack is a (pl. grana). Inside each thylakoid is a fluid-filled area called the or . Surrounding the grana is the , a semi-fluid medium between the second and third membranes. Thylakoid membranes are packed with chlorophyll a and accessory pigments that absorb light energy to initiate photosynthesis. Extensive membrane folding and structure provides plenty of membrane space for pigment molecules to interact and absorb light energy.

Although photosynthesis consists of several chemical reactions, the pathway can be separated into two major stages: the and the light-independent reactions. The light-independent reactions are also called the dark reactions or the .

Photosynthesis: An Overview Quiz | 10 Questions

The carbohydrates produced by plants and algae during photosynthesis provide enough energy to support life on Earth. Sunlight provides an energy source, but creating carbohydrates also requires a source of carbon atoms. During photosynthesis, inorganic carbon dioxide (CO2) gas is converted into organic molecules (glucose, C6H12O6).

As the primary producers of organic molecules on land, plants are structured to facilitate photosynthesis. Leaves have a flattened shape that provides a large surface area for capturing sunlight. The outer layers of a leaf form protective layers called the . In the epidermal layer on the underside of a leaf, pores called allow for entry and exit of the photosynthetic gases. Coating both the top and bottom epidermal layers is a waxy to reduce water loss.
