"R.H. Whittaker gave the Five Kingdom classification for living organisms. He categorized living organisms based on multiple characteristics such as cellular structure, mode of nutrition, body organization, reproduction, phylogenetic relationship, etc. These five kingdoms were Monera, Protista, Fungi, Plantae and Animalia. Kingdom Plantae includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis. The plant kingdom has the following characteristic features: 1. They are non-motile. 2. They make their own food hence are called autotrophs. 3. They reproduce asexually by vegetative propagation or sexually. 4. These are multicellular eukaryotes. The plant cell contains the outer cell wall and a large central vacuole. 5. Plants contain photosynthetic pigments called chlorophyll present in the plastids. 6. They have different organelles for anchorage, reproduction, support and photosynthesis."
