Chlorenchyma and aerenchyma differ in that chlorenchyma is a specialized parenchyma tissue that contains chloroplasts and performs photosynthesis, whereas aerenchyma is a spongy tissue with significant air spaces.
Aerenchyma:
Aerenchyma is a type of modified parenchyma in which the cells are organized with regular air spaces or air chambers to allow gases to diffuse and provide buoyancy to aquatic plants like lotus and water hyacinth.
It helps in the in and out-diffusion of oxygen.
Final Answer: Photosynthesis: chlorenchyma: :buoyancy: aerenchyma
