- Acrocyst — A temporary spherical anatomical structure or protective vesicular sac formed during the reproduction of certain colonial hydrozoans, protecting eggs or planulae.
- Airozome — An extremely rare and niche scientific cytological term used to describe a hypothetical or modified intracellular vesicular structure, rich in enzymes or aerobic components, involved in microscopic transport mechanisms, cellular respiration, or metabolic adaptation in hyper-oxygenated environments. The concept is investigated in comparative cellular morphology studies to understand the compartmentalization of biochemical processes within advanced cytoplasmic organelles.
