In the question, we have four solutions for four different questions.
00:04
So, talking about the first question, it is related with the first cell.
00:12
The endosimbion theory states that some of the organelles in today's eukriotic cell were once preocriotic microbes.
00:36
In this theory, the first eucreotic cell was probably an amoeba -like cell that got nutrients by the phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosome.
01:13
Some of these amoeba -like organism ingested prokiotic cells that then survive within the organism and develop a symbiotic relationship.
01:24
Microchondia formed when bacteria capsule of aerobic respiration were ingested.
01:28
Chloroplast formed when a prokriotic cell were ingested.
01:33
They eventually lost their cell wall and their cell wall much of their dna because they were not of benefited within the host cell.
01:41
Microchondia and chloroplast cannot grow outside their host cell.
01:46
And also these, the mitochondia and chloroplast, they are semi -autonomous organelles.
02:15
As they have their own dna contents.
02:20
Now, moving to the second part of this question is related with the endosymbiotic theory and its application.
02:36
So, if we talk about the evidences for this basis, chloroplasts are the same size as prokriotic cell, divided by binary fusion.
03:12
Unlike the fts protein that is present in the bacteria at their division plane, the mitochondia are the same size as prochriotic cell...
