Answer:
With the advancement of knowledge on living world, scientists classified the living organisms into two groups: Plantae, i.e., Plant kingdom and Animalia, i.e., Animal kingdom.
The Plantae is characterised by:
1. Nutrition depends on light energy,
2. Presence of rigid cell wall, and
3. Most of them remain rooted in the soil.
The Animalia is characterised by:
1. Ingestion of food, and
2. Members are usually motile.
Later on, with the advancement of knowledge on microorganisms, i.e., single-celled microscopic organisms, it was thought that the above system is inadequate.
In the earlier system, scientists placed bacteria, microscopic algae and fungi under plant kingdom, because:
1. They are relatively immobile, and
2. They are not able to ingest food
