They are mostly aquatic (marine or freshwater) or inhabit damp environments. Thallophyta: They have a rudimentary body structure and are known as the thallus, which means their body structure is not highly differentiated. Thallophytes, gymnosperms, angiosperms, bryophytes, and pteridophytes are the five subgroups. The million species that make up the Kingdom Plantae are divided into five subgroups based on characteristics such as the complexity of their plant bodies, the existence or absence of a vascular system, and how they carry seeds. For photosynthesis, reproduction, and support, they have a variety of cell organelles. Chlorophyll is found in their cells, which aids in photosynthesis. They’re all non-motile, eukaryotic, multicellular, and autotrophic creatures. Plantae is a large kingdom with approximately 2 million distinct species.
