Explanation

Animals are classified into two main groups:

1. Invertebrates (animals without a backbone). Examples: insects, spiders, squids, octopuses, starfish, corals, worm
2. Vertebrates (animals with a backbone. Examples: fish, amphibians, reptiles, birds, mammals (including humans)

Explanation

• Fungi are multicellular organisms, consisting of many cells that work together to form complex structures like mushrooms and molds.
• They have modified cell wall and nucleus.
• They have not chlorophyll.
• Animals, including humans, are multicellular organisms made up of many cells that work together to form tissues, organs, and systems.
• They have modified nucleus but don't have cell wall.
• They have not chlorophyll.
• Bacteria are unicellular organisms.
• They have cell wall but don't have proper nucleus.
• It doesn't contain chlorophyll.
• It is used to make medicines, yogurt and cheese.

Explanation

• Plants are multicellular, composed of many cells that work together to form roots, stems, leaves, and other structures.
• They have modified cell wall and nucleus.
• They have chlorophyll.
• Algae are unicellular with proper cell wall and nucleus.
• It contain chlorophyll.
• It causes diseases: Cutleria, Ulva and Volvox.

• Examples: Axes, knives, chisels, plough nall, sharpener, iron nails and pins (push pin).

Explanation

In 1969, Whittaker proposed a system of classification that divided all living organisms into five kingdoms:

1. Monera (bacteria and cyanobacteria)
2. Protista (protozoa, algae, and slime molds)
3. Fungi (mushrooms, molds, and yeasts)
4. Plantae (plants)
5. Animalia (animals)

Explanation
