Question

I am a double-membraned cell organelle. I produce energy-rich molecules called ATP. I have my own genetic material. Who am I?

A. Cell membrane
B. Plastid
C. Nucleus
D. Mitochondrion​

Answer 1

Mitochondria and chloroplasts are the cell organelles that are double membrane bound.

Mitochondria:-

Characteristics:

Mitochondria are surrounded by two membranes designated as outer and inner membrane. The outer membrane is smooth and forms the continuous limiting boundary of the mitochondria whereas the inner membrane forms a number of infoldings called the cristae. Due to the presence of two membranes, the organelle is partitioned into two distinct chambers filled with aqueous fluid.

The matrix contains single circular dsDNA molecule, a few RNA molecules, 70S ribosomes and the components required for the synthesis of proteins. The matrix also contains enzymes for TCA (Tricarboxylic acid) cycle.

Answer 2

You are a D. Mitochondrion! You are a double-membraned organelle found in the cells of eukaryotic organisms. You are responsible for producing energy-rich molecules, such as ATP, through a process called cellular respiration. You also contain your own DNA, which is essential for your function and replication.
