1. a protein structure found in the chloroplasts of algae and some plants that is involved in carbon dioxide fixation during photosynthesis
Usage: biology

Examples

• The pyrenoid serves as a site for carbon concentration in algal cells.
• Researchers observed pyrenoids in the chloroplasts of green algae under the microscope.
• The pyrenoid contains the enzyme RuBisCO, which is essential for photosynthesis.
• Some algae have multiple pyrenoids within each chloroplast.
• The structure of the pyrenoid varies among different species of algae.
• Scientists study pyrenoids to understand how algae efficiently capture carbon dioxide.
