Difference Between Chlorophyll and Chloroplast | Definition, Characteristics, Function, Comparison
A chloroplast is an organelle within a plant cell, where photosynthesis What is the difference between chloroplast pigments and chlorophyll pigments?. Quantitative Relations between Chlorophyll and. Cytochromes in Chloroplasts. H. LUNDEGARDH. Penningby, Sweden. (Received Marcb 21, Chlorophyll helps in trapping solar energy to split water molecule. Chloroplasts help in synthesis of carbohydrates. Difference between.
It has a similar structure to that of heme group of hemoglobin and cytochromes and is derived from protoporphyrin which contains polycyclic, plana tetrapyrrole ring. Photosynthetic organisms contain various types of chlorophyll such as Chl a, Chl b, Chl c, Chl d. These molecules differ in their substituents group on the tetrapyrrole ring.
A cyclopentanone ring attached with a carboxylic ester group, with pyrrole ring fused to it.
The pyrrole ring IV of Chl a and Chl b contains two extra hydrogen atoms. In bacteriochlorophylls rings, II and IV are in reduced form. Chlorophyll mostly absorbs in blue and somewhat red portions of the electromagnetic spectrum, hence it reflects green color. In producer autotrophs these green color traps light energy from the sun, which combines with carbon dioxide and water into sugars. This process is for the preparation of food in photosynthesis and further, it helps in gaining energy for the body growth.
Definition of Chloroplast Like mitochondria, they chloroplast are also bounded by a double membrane, the outer membrane, and the inner membrane. The outer membrane is believed to be the origin of eukaryotic cells and is permeable to small molecules and ions. While the inner membrane encloses the internal compartment. The fluid inside the double-membrane is called stroma. This compartment contains floating, flattened, tiny membranes surrounding vesicles or sacs called thylakoids.
These are arranged in a groups called granum. There are numerous grana present in each chloroplast and are interconnected by stromal lamellae. The thylakoid membrane lamellae are the site of Light reaction and ATP synthesis. Whereas the aqueous phase of the inner membrane — the stroma contains most of the enzymes required for carbon assimilation.
Thus thylakoid membrane present in the chloroplast is the location for ATP synthesis and Light reactions. This ATP is used by stroma to store trapped energy in the form of carbon-carbon bonds of carbohydrates. As Chloroplast is found in bacteria, it divides by the process of binary fission, as occur in bacteria. The chloroplast is considered as the semi-autonomous structure and contains 70S ribosomes prokaryotic-type. The light-dependent reactions happen inside the thylakoid.

Plants have both mitochondria and chloroplasts. This model of a chloroplast shows the stacked thylakoids. The space inside a thylakoid is called a lumen. Image via Guillermo Estefani artinaid.
Difference Between Chlorophyll and Chloroplast (with Comparison Chart) - Bio Differences
Both mitochondria and chloroplasts convert one form of energy into another form that cells can use. How did plants get chloroplasts? Chloroplasts were once free-living bacteria! Being Green Chlorophyll, a green pigment found in chloroplasts, is an important part of the light-dependent reactions.
Difference between Chlorophyll and Chloroplast
Chlorophyll soaks up the energy from sunlight. It is also the reason why plants are green. You may remember that colors are different wavelengths of light. Chlorophyll captures red and blue wavelengths of light and reflects the green wavelengths. Plants that lose their leaves in the winter start breaking down chlorophyll in fall. This takes away the green color of leaves. Image by John Fowler.
