This is just an educated guess. As the purple pigment, caused by anthocyanins, are on the bottom side of the plant, their purpose could probably be to direct the light. Specifically, a purple pigment on the bottom of the plant would absorb certain wavelengths near the purple spectrum, and reflect other wavelengths back toward the portion of the plant with chlorophyll. In this way, light does not simply pass through the leaf, instead it is reflected back in towards the chlorophyll to maximize the amount of light being used for photosynthesis.

What process occurs in prokaryotes but not in eukaryotes?
Naddika [18.5K]

Explanation:

In the given question, the options are not provided in the question and neither they are found anywhere therefore based on the previous knowledge this can be answered.

Since both the prokaryotes and eukaryotes are living therefore they perform the metabolism or chemical reactions in the form of process.

Both eukaryotes and prokaryotes perform almost similar process like the cellular respiration, photosynthesis by green colored organisms, the Central dogma related process like the replication, transcription and translation.

The central dogma related processes differ in these process only in terms of the site they are performed and a few modifications which are characteristics of the eukaryotic cells.

In prokaryotes, the transcription and translation are coupled and takes place in the cytosol whereas in eukaryotes transcription in the nucleus and translation in the cytosol.

Also in eukaryotes, modifications like the splicing, alternative splicing, capping and tailing are observed which are not observed in the prokaryotes.
