It is false statement because Mitochondrion is present in all eukaryotic cells; Like plant cells;Fungi etc.Mitochondrion is double membrane enclosed cell organelle.which Is the semi autonomous organelle.It is known as the power house of the cell as this is the site for cellular respiration and ATP synthesis takes place in mitochondrion.

2.An atom or molecule that loses an electron are oxidised .True

Because During the  process of Oxidation;atom or molecule loses an electron and loses its energy.and thus the molecule is considered as oxidised.The oxidation state of molecule which loses an electron increases during the process of oxidation.
