Whittaker proposed five kingdoms: -
1)Plantea
2)Fungi
3)Monera
4)Animalia
5)Protista
PLANTEA KINGDOM
the plant kingdom has been divided into five subgroups. They are as follows:
Thallophyta
Bryophyta
Pteridophyta
Gymnosperms
Angiosperms
Thallophyta
All the plants that lack a well-differentiated body structure belong to the subgroup Thallophyta. Thallophytes are commonly known as algae. The majority of them are aquatic. Some examples are Spirogyra, Chara, Ulothrix, etc
Bryophyta
Bryophytes have differentiated plant body like stem, leaf structures. But they lack a vascular system for the transportation of substances across the plant body. Bryophytes are found in both land and aquatic habitats, hence are known as amphibians of the plant kingdom. Mosses and Marchantia belong to this subgroup.
Pteridophyta
Pteridophytes have well-differentiated structures such as stem, root, leaves as well as a vascular system. Ferns, horsetails, Marsilea are some common examples of Pteridophytes.
Gymnosperms
Gymnosperms are plants that have well-differentiated plant body, vascular system and they bear seeds. The term is derived from Greek words, gymno: naked and sperma: seed. The seeds of gymnosperms are naked which means they are not enclosed within a fruit. The perennial, evergreen woody trees belong to this group. Pines, deodar, redwood, etc. are few examples.
Angiosperms
Angiosperms are also seed-bearing plants with well-differentiated plant body. The word is derived from Greek words: angio: covered and sperma: seed. Unlike gymnosperms, seeds of angiosperms are enclosed inside the fruits. Angiosperms are commonly known as flowering plants. Examples include the Mango tree, pomegranate plant, etc. Seeds germinate from embryonic leaves called cotyledons.
Depending on the number of cotyledons present in seeds, angiosperms are divided into two: monocotyledons (or) monocots and dicotyledons (or) dicots.
Cryptogams and Phanerogams
The plant kingdom has been classified into two groups ‘cryptogams’ and ‘phanerogams’ based on their seed formation ability.
Cryptogams are plants that do not have well-developed or conspicuous reproductive organs. They have hidden reproductive organs and don’t produce seeds. The thallophytes, the bryophytes and the pteridophytes are ‘cryptogams’. Reproduction in all the three groups occurs through spore formation.
Plants that have conspicuous reproductive organs and produce seeds are called ‘phanerogams’. Gymnosperms and Angiosperms belong to the group phanerogams

They are kingdom monera, kingdom protista,kingdom fungi,kingdom plante,kingdom animalia
Explanation of one kingdom that is monera
They do not have nucleus or organelles. They are multicellular organism . They may or may not have cell wall . They are autotrophics. Examples are as follows blue green algae , bacteria,anabaena etc......
