Question

Difference between chloroplasts,chromoplasts and leucoplasts

Answer 1

Answer:

Explanation:

All of the above are plastids; that is pigment filled organelles found in plant cells. Based on the pigment(colored chemical substances) in the plastid they can be of 3 types as given in your textbook.

1. chloroplast. This plastid has a green colored pigment that helps in photosynthesis. The chlorophyll present in them is called chlorophyll a and chlorophyll b. Don't worry about what they mean. They're just types of pigments. Now, these chloroplasts can convert into chromoplast based on certain conditions.  
2. Chromoplast. These plastids exhibit colors such as red/orange/yellow. For example the red color of apple is because the chromatids are present in the fruit wall giving it it's characteristic color. These plastids get their characteristic color because of the presence of certain compounds called carotenoids. Again; don't worry much about it but just remember they don't have chlorophyll because chlorophyll is for green colored cells. These plastids are also present in flower petals.
3. Leucoplast. These are the boring colorless plastids. They don't have any chemical pigment giving them any color. These leucoplasts however boring they look interestingly can change into chloroplasts or chromoplasts whenever the need comes. You will find these colorless plastids for example inside potato. Their major function is storage. They store starch/oil or any form of carbohydrates.

In your book they have given the correct co-relation but the order is messed up.

Hope this helps you :)
