Verified step by step guidance
1
Step 1: Begin by understanding the medulla's role in a eukaryotic cell. The term 'medulla' in this context refers to the inner region of the cell, which is often associated with energy production and metabolic activity.
Step 2: Recall the primary function of each organelle listed in the options: Lysosome (digestion and waste removal), Endoplasmic Reticulum (protein and lipid synthesis), Golgi Apparatus (modification and transport of proteins), and Mitochondrion (energy production through ATP synthesis).
Step 3: Focus on the mitochondrion, which is known as the 'powerhouse of the cell.' It is responsible for producing ATP via cellular respiration, a process that occurs in the inner membrane and matrix of the mitochondrion.
Step 4: Relate the mitochondrion's function to the medulla of the cell. The medulla is rich in mitochondria because it is the site of high metabolic activity, requiring significant energy production.
Step 5: Conclude that the mitochondrion is the organelle primarily found within the medulla of a eukaryotic cell, as it aligns with the energy-intensive processes occurring in this region.
