Difference between Leguminous and Non-Leguminous Plants

Leguminous and non-leguminous plants belong to the flowering families in the Plant kingdom. The leguminous plants are well known for their nitrogen-fixing capacity; however, many non-leguminous plants also fix atmospheric nitrogen.

Refer: What are the Uses of Legumes?

Let us differentiate between the two types of plants in the table below:

Leguminous Plants

Non-leguminous Plants

Description

Leguminous plants are flowering plants that belong to the family Fabaceae.

Non-leguminous plants are flowering plants that belong to different classes except Fabaceae.

Family

All leguminous plants belong to the Fabaceae family. Fabaceae is the third-largest family of flowering plants.

Orchidaceae and Asteraceae are two of the many non-leguminous families. They are the two largest families in the plant kingdom.

Leaves

The leaves are pinnate, compound and stipulated.

The leaves can be simple or compound; stipulated or unstipulated.

Symbiotic Relationship

They form symbiotic relations with the bacteria Rhizobia.

Many dicotyledonous plants form symbiotic relations with actinomycetes. E.g., Frankia

Fruit

The fruit is a legume or pod.

The fruits are of different types.

Use

  • Legumes are the staple food in the human diet, rich in proteins and fibres.
  • It is also used as fodder for domesticated livestock.
  • They are used in crop rotation to fix the nitrogen deficiency in the soil.
  • Non-leguminous plants can be used in industries, in the human diet, for animal grazing and many more such activities.

Frequently Asked Questions

Are Rhizobium and legume symbiotic organisms?

Yes, Rhizobium and legumes are a symbiotic organism. Rhizobium supplies amino acids to the plants and receives organic acids in return.

What is non-symbiotic nitrogen fixation?

The fixing of nitrogen by free-living microbes in the soil, not associated symbiotically with plants is known as the non-symbiotic nitrogen fixation.
