How are organisms in the plant kingdom divided?
Within the plant kingdom, plants are divided into two main groups. The largest group contains the plants that produce seeds. The other group contains the seedless plants that reproduce by spores. It includes mosses, liverworts, horsetails, and ferns.
What are the main points of plant kingdom?
The plant kingdom has the following characteristic features:
- They are non-motile.
- They make their own food hence are called autotrophs.
- They reproduce asexually by vegetative propagation or sexually.
- These are multicellular eukaryotes.
- Plants contain photosynthetic pigments called chlorophyll present in the plastids.
What organisms are in the plant kingdom?

Which is the second largest kingdom of organisms?
The Plant or Plantae kingdom encompasses all flowering plants, mosses and ferns. Plants are multi-celled, complex organisms and are considered Autotrophic. This means that plants create their own food through photosynthesis. The Plant kingdom is thought to be the second largest with over 25,000 known species.

In his Systema Naturae, first published in 1735, Carolus Linnaeus distinguished two kingdoms of living things: Animalia for animals and Plantae (Vegetabilia) for plants. He classified all living organisms into two kingdoms – on the basis of nutrition and locomotion (mobility).
What are the five kingdoms of living organisms?
He categorized living organisms based on multiple characteristics such as cellular structure, mode of nutrition, body organization, reproduction, phylogenetic relationship, etc. These five kingdoms were Monera, Protista, Fungi, Plantae and Animalia.
