  Kingdom Protista: The Diverse World of Eukaryotic Microorganisms Kingdom Protista is a taxonomic grouping of eukaryotic microorganisms that do not fit into any of the other kingdoms of life, including Animalia, Plantae, Fungi, and Monera. This kingdom is a diverse group of organisms that exhibit characteristics from multiple kingdoms. Characteristics of Kingdom Protista 1. Eukaryotic cells: Protists have eukaryotic cells, which means their cells have a true nucleus and other membrane-bound organelles. 2. Unicellular or multicellular: Protists can be either unicellular or multicellular, and some may even form colonies. 3. Autotrophic or heterotrophic: Protists can be autotrophic (producing their own food) or heterotrophic (obtaining food from other sources). 4. Lack of specialized tissues: Protists lack specialized tissues and organs, which distinguishes them from animals and plants. Classification of Kingdom Protista Kingdom Protista is divided into three main categories: 1. ...

  Kingdom Monera: The World of Single-Celled Organisms Kingdom Monera, also known as Monerans, is a group of single-celled microorganisms that lack a true nucleus and other membrane-bound organelles. This kingdom is composed of prokaryotic cells, which are the simplest form of life on Earth. Characteristics of Kingdom Monera 1. Prokaryotic cells: Monerans lack a true nucleus, mitochondria, and other membrane-bound organelles. 2. Single-celled: Monerans are unicellular organisms, meaning they consist of only one cell. 3. Small size: Monerans are typically microscopic, ranging in size from 0.5 to 5.0 micrometers. 4. Lack of chloroplasts: Monerans do not have chloroplasts, which are organelles responsible for photosynthesis. 5. Cell wall: Monerans have a cell wall that provides structural support and protection. Types of Kingdom Monera According to NCERT, Kingdom Monera is divided into two main groups: 1. Bacteria (Eubacteria)     - Characteristics: Bacteria are prokaryot...
