For a billion years before plants, insects, fish or any multi-cellular creatures existed life consisted of single celled organisms in the vast oceans. And for that billion years the earth was a remarkably geologically stable hot environment. Prokaryotes were the dominant life-form but eukaryotes ex...
A human-centered approach to the fundamentals of cell biology with a focus on the power plants of the cell - mitochondria. The cell is a powerful case study to help us explore the functional logic of living systems. All organisms, from single-celled algae to complex multicellular organisms lik...
The oldest of the geologic eons is the Hadean, which began about 4.6 billion years ago with the formation of Earth and ended about 4 billion years ago with the appearance of the first single-celled organisms. This eon is named after Hades, the Greek god of the underworld, and during this...
Archaea are single cell organisms without a nucleus and other membrane-bounded organelles. Archaea are not… Read More Bacteria – Definition, Structure, Types & Infections Bacteria are single-celled microorganisms. Because they don’t have nuclei or membrane-bound organelles, they are classified… Re...
Unicellular:Unicellular organism consists of only a single cell, unlike multicellular organisms. They are also popular as single-celled organisms. These single-celled organisms are classified into two main categories of organisms such as eukaryotic organisms and prokaryotic organisms. Forex: Protozoa, Esch...
Every animal on Earth experiences the world in a different way, using a unique suite of senses to detect its physical environment. Tracing the evolution of these mechanisms is a story that takes us through life's journey - from single-celled organisms to more complex, sentient beings. Brian ...
Like proper plants, kelp uses photosynthesis to turn water, carbon dioxide and sunlight into food. However, unlike plants, kelp exist in the kingdom Protista, which contains mainly single-celled organisms. Kelp is the largest member of the broad seaweed category, though there are smaller members...
Christian pays more attention to the beginning of change, such as explaining the physics and chemistry of the big bang, and the biology and anthropology behind the evolution of humans from single celled organisms to more recognizable primates. For inspired teachers, parents or lifelong learners, Gat...
