Apoptosis in Microalgae: Human-like Cell Death in the First Photosynthetic Organisms
The surprising discovery: apoptosis in microalgae For most people, programmed cell death — apoptosis — is a concept tied to multicellular organisms that rely on tightly regulated tissues and organs. Yet recent observations suggest that apoptosis-like processes occur in microalgae, the tiny, photosynthetic single-celled organisms that powered some of the earliest ecosystems on Earth. In…

Microalgae Cell Death Mirrors Human Apoptosis
Groundbreaking finding: apoptotic bodies in a photosynthetic unicellular organism A landmark study reports that the first photosynthetic organism, and the first unicellular organism, can produce apoptotic bodies during cell death. Researchers observed microalgae entering a controlled decline, with fragmentation of cellular content into vesicle-like bodies that are later cleared by neighboring cells. This process mirrors…
