- This kingdom includes multicellular eukaryotes, organisms containing chlorophyll that are vital for photosynthesis commonly called plants.
- Some plants behave like autotrophs.
- True plants collect their food in the form of starch or sugar.
- Some plants also behave like heterotrophic such as insectivorous plants or parasites. For example:- Bladderwort and Venus flytrap (Insectivorous plant), Cuscutta (Parasite).
- Plants are non-motile.
- The characteristics of a living plant include movement, nutrition, respiration, sensitivity, reproduction, excretion, and growth.
- Plants have a rigid structure that surrounds the cell membrane known as the cell wall which is mainly made up of cellulose.
- There are two distinct stages in the life cycle of plants. The First is the diploid sporophytic stage and the second is the haploid gametophytic stage which alternate with each other. The lengths of the haploid and diploid stages, and whether these stages remain independent or dependent on others, vary between different groups in plants. This process is known as alternation of generation.
- Classification based on growths habits:- Herbs, Shrubs, Trees, Climbers, Creepers, etc.
- Kingdom Plantae is classified by tissue structure into non-vascular ( Mosses) and Vascular plants including xylem and phloem.
- Plants include vascular tissue, roots, leaves, waxy cuticles, stomata to regulate water evaporation, and the tough outer layer that are an adaptation to life on land.
- Healthy plants include firm leaves, well-formed flowers and fruits, and a well-developed root system.
- Plants can reproduce asexually by vegetative propagation and by a sexual method.
