Mitochondria are often referred to as the: ((MCAER 2014))

✅Explanation: Mitochondria are often referred to as the "powerhouses of the cell" because they are the primary site of cellular respiration. This process breaks down nutrients to produce energy in the form of ATP.

📌 Other Options Explanations:
-Option B: Ribosomes are involved in protein synthesis.
-Option C: The endoplasmic reticulum is involved in protein synthesis and lipid synthesis.
-Option D: The Golgi apparatus is involved in packaging and modifying proteins.

🔑Key Points:
-Mitochondria are rod-shaped cell organelles that are considered to be the power generators of the cells.
-They convert the oxygen and nutrients into adenosine triphosphate.
-The number of mitochondria varies by the organism, tissue, and cell type.

🛑Additional Information:
-For example, the red blood cells do not have mitochondria whereas the liver cells have more than 2000 mitochondria.
-Cell respiration is carried out by mitochondria.
-Krebs’ cycle takes place in the mitochondrial matrix and the electron transport chain occurs in the inner mitochondrial membrane.
-They regulate cellular metabolism.
-The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.
-A chloroplast is a type of organelle known as a plastid, characterized by its two membranes and a high concentration of chlorophyll.
-The Golgi apparatus, sometimes called the Golgi complex or Golgi body, is responsible for manufacturing, warehousing, and shipping certain cellular products, particularly those from the endoplasmic reticulum (ER).
