It includes all plants (eukaryotic chlorophyll-containing organisms with cellulosic cell wall).
Some are partially heterotrophic such as the insectivorous plants (e.g. Bladderwortand Venus fly trap) or parasites (e.g. Cuscuta).
Plantae includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms.
Life cycle of plants has two distinct phases – the diploid sporophytic & the haploid gametophytic – that alternate with each other.
The lengths of the haploid and diploid phases, and whether these phases are free living or dependent on others, vary among different groups in plants. This phenomenon is called alternation of generation.
