Armed Parenchyma Storage parenchyma functions to store or … Aerenchyma is made of many large air filled cavities in the submerged parts of some marsh plants - it gives the submerged parts access to a supply of air. Chlorenchyma tissue is the parenchyma tissue modified to carry out photosynthesis, while aerenchyma tissue is the parenchyma tissue that contains enlarged air spaces. Their role is largely based on their location in the plant; that can determine whether they will serve in storage, photosynthesis, or damage repair.
