Difference Between Chlorophyll and Chloroplast: All You Should Know
Green plants depend on chlorophyll in their cells to produce food and nutrition. The only chemical compound capable of directly deriving nutrition from the sun’s rays, chlorophyll is the prime reasons for the green colour of plants.
Chloroplast, on the other hand, refers to the organelle where photosynthesis takes place. It is vital for NEET aspirants to understand the difference between chlorophyll and chloroplast.
One of the major differences between the two, for instance, is that chlorophyll is present in the mesophyll cells, while chloroplast occurs in the cytoplasm of plant cells.
Chlorophyll Definition and Characteristics
In simple terms, chlorophyll refers to a green pigment in plants that trap sunlight and use its energy to provide nutrition for the plants, through a process known as photosynthesis. Its characteristics include the following
Chlorophyll responsible for plants to grow healthy.
It causes the green colour in plants and trees.
Produces food in plant cells, primarily found in chloroplast.
Chlorophyll’s structure is similar to that of haemoglobin and cytochromes, both of which are derived from protoporphyrin.
Chlorophyll is often termed a cell’s powerhouse, similar to mitochondria. This is because this enzyme is responsible for ATP synthesis and energy derivation within the cell.
Chlorophyll absorbs blue and red wavelengths of light while reflecting the green.
Chloroplast Definition and Characteristics
Chloroplast can be termed as the organelles or the site where chlorophyll traps sunlight and synthesizes ATP in a plant cell. Listed below are some characteristics of chloroplast that you need to remember –
This organelle is present in all green plants.
Chloroplast is responsible for a wide range of activities apart from photosynthesis, such as carbon assimilations, light reactions and much more.
A fluid stroma lies enclosed in a double membrane.
Thylakoids, which are floating sacs, are arranged as granum inside this chloroplast.
Distinction Between Chlorophyll and Chloroplast
Now that you understand the characteristics of both chlorophyll and chloroplast, here is a detailed look at the difference between chlorophyll and chloroplast.
Now that you know the difference between chlorophyll and chloroplast, you should also learn about the difference between two types of chlorophyll.
Difference Between Chlorophyll a and Chlorophyll b
Both chlorophyll a and chlorophyll b are essential for photosynthesis. However, there are some major distinctions between the two types, which help them to work together.
Stages of Photosynthesis
Apart from the information above, you must also know that photosynthesis has two distinct stages. Stage I is known as the light reaction, while Stage II is known as the Calvin Cycle.
In this first stage, plants use water to transform light energy into chemical energy. This chemical energy is stored in the form of NADPH and ATP. During this reaction, oxygen is released as a by-product.
In this phase, plants absorb carbon dioxide from air, combining this carbon with the stored chemical energy. After combination with NADPH and ATP, this stage produces glucose, which acts as nutrition for plants.
Q. What is the Primary DNA Type in Chloroplast?
Ans. Chloroplast contains DNA molecules of the cpDNA type.
Preparing for NEET
NEET biology preparation involves a lot more than simply learning about the difference between chlorophyll and chloroplast. It includes complicated topics, which can be difficult to understand and remember. Regular revision of chapters can help with your preparation. Moreover, access to the best study materials can be invaluable at such a time.
NEET may not always be straightforward, which is why you require conceptual knowledge about topics as well. For instance, one question may ask you what is the similarity between chlorophyll and haemoglobin. Answering such tricky questions require you to be thorough of each topic.
