Mitochondria or chondriosome (singular mitochondrion ,. Mitos means thread and chondrion means granules).an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
Numbers:- ranges from one to thousands.
Occurrence:- found only in eukaryotes.
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix.mitochondria have their own DNA and ribosome.
Function :- It is involved in respiration and thus produce energy for cell functions, that’s why mitochondrion is also called power house of cell.
