Mitochodaria is present in majority of cells and plastid is present only in in few.
Explanation:
Endosymbiosis theory explain that mitochondria and plastids arose from bacteria through engulfing by larger cells because mitochondria and plastids contain different DNA than cell nuclei.
Mitochondria were acquired before than plastids because mitochondria is present in majority of eukaryotic cell and some cell have plastids with mitochondria.This explain that after the endosymbiosis of mitochondria some cells did endosymbiosis with photosynthetic bacteria to acquire plastid.
The fact that most Eukaryotes possess Mitochondrial despite possession of plasmid, is an indication that some eukaryotes were able to engulf some photosynthetic bacteria,(endosymbiosis) after mitochondria endosymbiosis,This true because some early Eukaryotes possesses either the mitochondria, or its modified version or plastids.
Battery acid is acidic in nature so its pH will be more.if we add a base its acidity level decreases and it becomes a poor acid. here water acts as a base to decrease the pH value and acidic nature of a acid substance that is battery acid.
