- The Kingdom Plantae includes all eukaryotic chlorophyll-containing organisms having prominent chloroplasts and cellulosic cell walls.
- Mode of nutrition is mainly autotrophic. It occurs through the process of photosynthesis.
- However, some plants have heterotrophic mode of nutrition, such as Cuscuta which is a parasitic plant. The insectivorous plants like Venus Fly Trap are partially heterotrophic.
- The reserve food material is starch.
- Ecologically, they act as producers in an ecosystem.
Major groups of Kingdom Plantae:
An outline of plant classification is as follows:
- All plants are divided into two broad groups i.e. cryptogams and Phanerogamae
- Cryptogams include all plants that do not form seeds while phanerogams include plants with seeds.
- Cryptogamae includes Thallophyta, Bryophyta and Pteridophyta while Phanerogamae includes gymnosperms and angiosperms.
Thus, the major groups are:
- Thallophyta / Algae
- Bryophyta
- Pteridophyta
- Gymnosperms
- Angiosperms
