Meaning of Parenchyma

What is Parenchyma:

The organic tissue that both animal and plant organs possess, but in each case fulfilling certain functions as appropriate, is called parenchyma, hence, the animal parenchyma and the plant parenchyma are differentiated.

The parenchyma can also be referred to as parenchymal tissue or parenchymal tissue.

The term parenchyma is part of the studies of histology, a discipline that is responsible for studying organic tissues, their structures and their functions.

Animal parenchyma

The animal parenchyma is an essential tissue that allows the functioning of the various organs in which it is found and is studied by animal histology.

Among the parenchyma that can be mentioned in animals are the lungs, the kidneys, the brain, the liver, muscle tissue, and nervous tissue, among others.

For example, epithelial tissue is recognized as a parenchyma because it allows secretion of glandular epithelia.

Vegetable parenchyma

In botany, the fundamental plant tissue is called parenchyma, which is characterized by being abundant, spongy and being spread between plant organs.

The plant parenchyma is a tissue composed of cells with soft walls and various shapes that allow it to fill in the empty spaces between these organs.

In this sense, the plant parenchyma constitutes an extensive tissue that is numerous in the soft parts of plants such as leaves and fruits.

Likewise, depending on the location of the plant parenchyma, its function is to carry out essential and specialized activities for plants such as:

  • The nutrition.
  • The breathing.
  • Photosynthesis.
  • The reproduction.
  • The elaboration of essential substances.
  • The regeneration of plant tissues as new stems and roots.
  • Heal or repair damage to the stems and leaves.

Types of plant parenchyma

  • Chlorenchyma parenchyma: also called chlorophyll parenchyma or assimilator, it specializes in photosynthesis.
  • Reserve parenchyma: stores and transports nutritional substances. It is very abundant in the underground part of the plant, such as tubers, and in plants such as cacti.
  • Aeriferous parenchyma: it is characteristic of plants that develop in aquatic environments, it is responsible for storing and conducting the air inside the plants.
  • Aquifer parenchyma: it is characterized by storing water in those plants that are in dry environments.
