Which of the following lists events in the order in which they occurred? cambrian explosion, first eukaryotic cells, first animals, first land plants, evolution of photosynthesis evolution of photosynthesis, first eukaryotic cells, first animals, cambrian explosion, first land plants evolution of photosynthesis, first eukaryotic cells, cambrian explosion, first land plants, first animals first eukaryotic cells, evolution of photosynthesis, cambrian explosion, first land plants, first animals first eukaryotic cells, first animals, cambrian explosion, first land plants, evolution of photosynthesis

The correct answer is: evolution of photosynthesis evolution of photosynthesis, first eukaryotic cells, first animals, Cambrian explosion, first land plants

Evolution of photosynthesis most likely occurred 3.5 billion years ago, and Bacteria (prokaryotic cell) were the first organism that developed primitive forms of photosynthesis (without releasing oxygen). After photosynthesizing cyanobacteria evolved and started producing oxygen, eukaryotic cells appeared (2.7 billion years ago).

575 million years ago the first simple forms of animals (multicellular) such as Ediacara biota.

541 million years ago in Cambrian era, Cambrian explosion occurred. Almost all present animals appeared during this event.

The first land plants appeared around 470 million years ago.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
