Question

Write the most important characteristic feature of each of the following groups of organisms.

1. Monera
2. Fungi
3. Protista

Answer 1

1. Monera

1. The Monera Kingdom is a prokaryote.
2. This kingdom's organisms do not have a true nucleus.
3. These are the planet's oldest known microorganisms.
4. The nucleus does not protect its DNA.
5. They are unicellular
6. They reproduce by binary fission or budding.
7. The flagellum is their locomotory organ.
8. The cell wall is rigid and made up of peptidoglycan.
9. They contain 70s ribosomes.
10. They lack organelles such as mitochondria, plastids, endoplasmic reticulum, centrosome, lysosomes, Golgi bodies, etc.
11. They show different types of nutrition such as autotrophic, parasitic, saprophytic, heterotrophic, etc.

2. Fungi

1. Fungi are unicellular, heterotrophic eukaryotes, non-vascular and non-motile, that lack chlorophyll and are unable to prepare their own food through photosynthesis. As saprophytes, parasites, and symbionts, they exist.
2. The cell's nucleus and organelles are well defined.
3. The cell wall is composed of chitin, a complex nitrogen-containing sugar that provides toughness to the cell wall.
4. They store their food in the form of starch.
5. They have a sexual (by the release of pheromones) as well as an asexual mode of reproduction.
6. Examples include: mushrooms, yeast, etc

3. Protista

1. Unicellular with eukaryotic cells.
2. They are either free-living or parasitic.
3. Sexual (conjugation), asexual (binary fission), or a combination of the two modes of reproduction are all possible.
4. They are true eukaryotes and nucleated.
5. They use flagella and cilia for locomotion.
6. They are either autotrophic or heterotrophic.
