The correct answer is A. Mitochondria.
Mitochondria are organelles found in most eukaryotic cells. They are responsible for the production of ATP, the cell’s energy currency. ATP is produced by a process called oxidative phosphorylation, which takes place in the mitochondria’s inner membrane.
Plastids are organelles found in plant cells. They are responsible for photosynthesis, the process by which plants convert sunlight into energy. Plastids come in a variety of shapes and sizes, and they each have a specific function. For example, chloroplasts are the plastids that are responsible for photosynthesis.
Ribosomes are organelles found in both prokaryotic and eukaryotic cells. They are responsible for the synthesis of proteins. Ribosomes are made up of two subunits, a large subunit and a small subunit. The large subunit contains the rRNA, which is responsible for catalyzing the protein synthesis reaction. The small subunit contains the tRNA, which delivers the amino acids to the ribosome.
Lysosomes are organelles found in eukaryotic cells. They are responsible for the digestion of cellular debris and foreign substances. Lysosomes contain a variety of enzymes that can break down proteins, carbohydrates, lipids, and nucleic acids.
In conclusion, the correct answer is A. Mitochondria.
