The First living things on earth were single-celled bacteria an cyanobacteria, also known as blue-green algae.
Blue-green algae emerged about 3,500 mya.(million years ago).
It contains chlorophyll and was the first living organism to use photosynthesis o make energy using sunlight.
Over millions of years, the algae was able to produce enough oxygen to help più complex organisms to evolve.
True algae, which is regarded as a plant, evolved around 1,000 mya.
da 550 mya, multi celled plants began to appear, including seaweeds.
Algae and lichens were the first plants to appear on land.
Bryophyte plants emerged on land around 440 mya. Bryophytes are simple, seedless green plants.
Unlike vascular plants, which rvolved later, bryophytes cannot grow high above the ground because they do not have stems.
