Central to hornworts' enhanced photosynthetic ability is a microscopic structure called a pyrenoid. Found within their chloroplasts, pyrenoids act as CO₂ concentration chambers, ensuring that ...

“While rubisco by itself is bad at removing carbon dioxide, by forming this pyrenoid, the algae is able to increase the rate of carbon capture and circumvent the inefficiency of rubisco by itself.” ...

Photosynthesis is the process by which plants, algae and certain types of bacteria synthesise carbohydrates from carbon dioxide and typically water, using light as an energy source. The process ...
