Sea Slug Photosynthesis Mechanisms

The video discusses sap-sucking sea slugs, focusing on their unique ability to sequester chloroplasts from algae. These slugs use piercing teeth to feed on algae, absorbing chloroplasts that continue to photosynthesize within the slug's body. This process is remarkable because the chloroplasts require proteins typically produced by the algal nucleus. Recent findings suggest that some genetic elements from the algae have been transferred to the slug, enabling this photosynthesis to continue.

What is the sap-sucking sea slug also known as?

• Solar-powered nudibranch

• Sea anemone

• True nudibranch

• Sea cucumber

What is the primary function of the saag glossin's teeth?

• Migration patterns

How long can the chloroplasts continue to photosynthesize in the sea slug?

• A few minutes

• A few hours

• A few days

• Long periods of time

What percentage of proteins needed by the chloroplasts are made by the algal nucleus?

• 100%

• 50%
