what is chlorophyll ?
Chlorophyll
Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy.
Chlorophyll exists in several forms but chlorophyll a and chlorophyll b are the most common – typically found in higher plants and green algae. Chlorophyll c is found in certain marine algae and Chlorophyll d is found in certain species of cyanobacteria. Even rarer is Chlorophyll e – found only in some golden algae. Interestingly, chlorophyll has a similar structure to haemoglobin, which is found in red blood cells of vertebrates.
Do darker leaves have more chlorophyll?
Actually, plants that grow in shady regions contain chlorophyll b, which can absorb low-intensity light. The leaves of such plants are darker compared to the leaves of plants that grow in light with high intensity.
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 colour plastids. These cell organelles are present only in plant cells and are located within the mesophyll cells of leaves.
