organelles with an abundance of carotenoids but no chlorophyll

When looking for organelles with an abundance of carotenoids but no chlorophyll, we need to consider photosynthetic organisms that have alternative pigments. Chlorophyll is the primary pigment involved in photosynthesis, but there are other pigments like carotenoids that can also play a role in capturing light energy.

One example of organelles with an abundance of carotenoids but no chlorophyll can be found in rhodoplasts, which are the organelles responsible for photosynthesis in red algae. Red algae contain a red pigment called phycoerythrin, which masks the green color of chlorophyll and gives them their characteristic red color. This pigment allows them to absorb light at different wavelengths and carry out photosynthesis.

To find this information, you can search for photosynthetic organisms that have different pigments than chlorophyll. In the case of red algae, you can specifically search for their photosynthetic organelles called rhodoplasts and learn more about their pigment composition.
