Tree of Life

A representative from the various species in the world based on the Scientific tree of life in the number positions of clock:

1. BACTERIA, Bacteria (Prokaryotes)

• Bacteria are classified as prokaryotes, cells that do not contain a nucleus.
• Bacteria play an important role in recycling nutrients.

2. ALGAE, Plantae (Protists)

• Algae are classified as eukaryotes, cells that contain nucleus, like all plants and animals.
• Algae such as seaweeds are photosynthetic like plants, but lack leaves and roots.

3. TREES, Plantae (Plants)

• Plants use sunlight for photosynthesis to convert carbon dioxide and water into oxygen and other useful products.
• There are about 300,000 species of plants.

4. MUSHROOMS, Fungi (Fungi)

• Fungi are closer to animals than to plants, but are separate from bacteria, plants, and animals.
• Yeasts, molds, mushrooms are some examples. Yeast is used for bread and fermentation.

5. WORMS, Ecdysozoa (Invertebrates)

• Worms are animals without a backbone. They have digestive tract but lack sensory organs.
• Some earthworms have the ability to regenerate certain body segments.

6. BUTTERFLIES, Ecdysozoa (Invertebrates)

• The insects such as a butterfly have four stages in their life cycle, egg, larva, pupa and adult.
• Insects are ecologically helpful because they help in pollinating flowers.

7. SHELLS, Lophotrochozoa (Invertebrates)

• Seashells living in the sea have a hard protective outer layer.
• In the past, seashells have been used as a currency. They are also a source of calcium carbonate.

8. SEA STARS, Echinodermata (Invertebrates)

• Sea stars live at abyssal depths of the oceans.
• Sea stars have the ability to digest food outside of their body.

9. FISH, Chordata (Vertebrates)

• Fish are animals with a spine.
• Most fish are cold-blooded animals.

10. AMPHIBIANS, Chordata (Vertebrates)

• Amphibians are water-breathing as well as air-breathing animals.
• Salamanders are unique vertebrates that are capable of regenerating lost limbs, as well as other body parts.

11. BIRDS, Chordata (Vertebrates)

• Birds are warm-blooded animals. The wings are evolved from the forelimbs.
• Birds have a beak but have no teeth.

12. MAMMALS, Chordata (Vertebrates)

• Mammals are also warm-blooded animals and can produce milk.
• The human brains possess a unique part of the brain called neocortex that is responsible for higher functions such as language and reasoning.
