7 0

According to endosymbiotic theory, the chloroplast evolved as a result of engulfment and assimilation of a Cyanobacteria by an eukaryotic cell.

Explanation:

  • Endosymbiotic theory supports the view that ceratain organelles of the eukaryotic cell evolved as a result of engulfment of single celled organism.
  • Evidences  that support this theory is the presence of organellar DNA.
  • It is assumed that Mitochondria evolved as a result of engulfment and assimilation of an aerobic prokaryote while Chloroplast evolved due to engulfment and assimilation of a photosythetic prokaryote by an Eukaryote.
  • After the engulfment ,these organisms however escaped the phagocytosis and began to benefit the eukaryotic Host.
  • Soon it lost many of its Genes to the eukaryotic nucleus and became dependent on the Host.
  • Thus a symbiotic association was established between the prokaryote and the host.Giving rise to cell organelles.

There are almost 10,000 known bird species on the planet. How did they evolve into so many unique forms?
olga55 [171]

Answer:

Natural selection.

Explanation:

Imagine in the beginning there was a single species of bird. Naturally, this bird had to expand to the rest of the world, and was distanced as the continents drifted off. But this bird had to cope with various climates and environments. So the bird would gradually mutate over time. The bird in the jungles of central america would develop different colors and a shaped beak, and would better help it survive. This led to being the new normal for birds of this area. It would evolve to cover all the surviving birds in the region, until it is so drastically changed then it is a new species. There are so many different environments, each with its own challenges to overcome, so so many different bird evolve to survive them.
