Structure of a chromoplast?

Postby starswept » Sun Feb 11, 2007 11:56 pm

Hi,

I'm trying to find out how to describe the structure of a chromoplast for a biochemistry lab. I've found plenty of information on chloroplasts, and I would assume their structure would be similar to that of a chromoplast, just with different pigments. However, I haven't been able to find any information to back that up. Most pages simply describe the function of a chromoplast, and though I've asked a few tutors, none of them seem to know how a chromoplast is structured.

So, if anyone could tell me what their structure is like, or provide a link that explains it, I'd be extremely grateful. Thank you!

Chromoplasts are plastids responsible for pigment synthesis and storage. They, like all other plastids (including chloroplasts and leucoplasts), are organelles found in specific photosynthetic eukaryotic species.

Chromoplasts, in the traditional sense, are found in coloured organs of plants such as fruit and floral petals, to which they give their distinctive colors. This is always associated with a massive increase in the accumulation of carotenoid pigments. The conversion of chloroplasts to chromoplasts in ripening tomato fruit is a classic example.

Search in google as chromoplast+structure

Thank You.

Thank you, I appreciate your time. However I had that information already; I'm looking more specifically for the actual construction of a chromoplast, not its function. For example, when describing the function of a chloroplast, I wrote about the organization of thylakoids, stroma, grana, etc.
