Aquifer parenchyma: water storage function

What they are (definition)

Parenchymes are permanent plant tissues (adults) that originate mainly in meristems (tissue composed of fast growing cells and intense).

Main general characteristics of plant parenchyma:

- They are found in all vegetable organs;

- They have thin, thin and flexible primary walls;

- have vacuoles;

- Presence of schizogenic spaces (spaces between plant cells);

- They present varied formats;

- Parenchymal cells are not specialized.

Chlorophyll parenchyma

Gift in the leaves of vegetables. Cells of this type of parenchyma have chloroplasts and chlorophyll. The function of this tissue is to act in the photosynthesis process of plants.

Reserve parenchyma

They are responsible for storing substances made by the cell (oils, oxalate crystals, starch, proteins, etc.).

Reserve parenchyma is classified according to the substance that stores:

- Aquifer parenchyma: have the function of storing large amount of water. They are mainly present in plants that live in arid regions such as cacti.

- Air parenchyma: Common in floating aquatic vegetables, has the function of reserving air in the spaces between cells.

- Starch parenchyma: has the function of storing starch inside leukoplasts. It is common in tubers such as cassava and potatoes.

Some botanists believe the parenchyma is the most primitive tissue in plants.
