Question

Which of the following organelles is most likely to aid in the digestion of food particles?

• A. Rough endoplasmic reticulum
• B. Nucleus
• C. Lysosome
• D. Ribosome

Hint:

Associate the suffix "-lys-" with breakdown. "Lysosome" contains enzymes for lysis (breaking down). This simple word association can help you remember its primary function.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The question asks to identify the cell organelle responsible for intracellular digestion.

Step 2: Detailed Explanation:
Let's look at the function of each organelle:
\[\begin{array}{rl} \bullet & \text{1. Rough endoplasmic reticulum (RER): Its surface is studded with ribosomes, and its primary function is the synthesis and modification of proteins that are destined for secretion or insertion into membranes. } \\ \bullet & \text{2. Nucleus: This organelle contains the cell's genetic material (DNA) and controls the cell's growth and reproduction. } \\ \bullet & \text{3. Lysosome: These are membrane-bound organelles that contain a variety of hydrolytic enzymes. They function as the cell's "recycling center" or "digestive system," breaking down waste products, damaged organelles, and foreign material like bacteria or food particles brought into the cell via endocytosis. } \\ \bullet & \text{4. Ribosome: These are the sites of protein synthesis (translation), where genetic information from mRNA is used to build proteins. } \\ \end{array}\] Based on these functions, the lysosome is the organelle that aids in digestion.

Step 3: Final Answer:
The lysosome is the organelle most likely to aid in the digestion of food particles.
