In aquatic plants, parenchyma tissue forms large air cavities to aid in flotation. This specialized type of parenchyma is called aerenchyma.

Parenchyma cells have thin cell walls and are relatively unspecialized compared to other plant tissues. They are living cells with loosely arranged structures, allowing for large intercellular spaces.

Parenchyma is a simple permanent tissue consisting of relatively unspecialized cells with thin cell walls. These living cells are usually loosely arranged, leaving large intercellular spaces. Parenchyma tissue primarily functions in food storage but may also contain chlorophyll for photosynthesis, ...

The process by which cells in meristematic tissue take up permanent shapes, sizes, and functions is called differentiation, which leads to the development of various types of permanent tissues in plants.

Permanent tissues are composed of cells that have differentiated and taken up specific roles, whereas meristematic tissue consists of actively dividing cells capable of producing new cells for growth and repair.
