Category: Photosynthesis

At the cellular level,  the photosynthesis process takes place in cell organelles called chloroplasts. These organelles contain a green-coloured pigment called chlorophyll, which is responsible for the characteristic green colouration of the leaves. As already stated, photosynthesis occurs in the leaves and the specialized cell organelles responsible for this process is called the chloroplast. Structurally,…

Photosynthesis reaction involves two reactants, carbon dioxide and water. These two reactants yield two products, namely, oxygen and glucose. Hence, the photosynthesis reaction is considered to be an endothermic reaction. Following is the photosynthesis formula: 6CO2    +   6H2O  —>  C6H12O6  + 6O2 Unlike plants, certain bacteria that perform photosynthesis do not produce oxygen as the by-product of photosynthesis. Such…

Where Does This Process Occur? Chloroplasts are the sites of photosynthesis in plants and blue-green algae.  All green parts of a plant, including the green stems, green leaves,  and sepals – floral parts comprise of chloroplasts – green color plastids. These cell organelles are present only in plant cells and are located within the mesophyll cells of leaves. Factors Affecting PhotosynthesisPhotosynthesis…

The word “photosynthesis” is derived from the Greek words phōs (pronounced: “fos”) and σύνθεσις (pronounced: “synthesis“)Phōs means “light” and σύνθεσις means, “combining together.” This means “combining together with the help of light.” Photosynthesis also applies to other organisms besides green plants. These include several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria. These organisms exhibit photosynthesis just…
