What is the term for a microscopic structure in a cell that carries out individual functions?Multiple choice question.OrganOrganelleMoleculeAtom

Step 1: Break Down the Problem

The question asks for the correct term that refers to a microscopic structure within a cell responsible for performing specific functions.

Step 2: Relevant Concepts

• Organ: A group of tissues that perform a specific function in an organism; larger than cell structures.
• Organelle: Specialized structures within a cell that perform unique functions (e.g., mitochondria, nucleus).
• Molecule: A group of atoms bonded together, but not specific to cellular structures.
• Atom: The basic unit of a chemical element, even smaller than a molecule.

Step 3: Analysis and Detail

Given the definitions:

1. Organ is clearly not correct because it refers to larger structures, not microscopic ones.
2. Molecule and Atom again refer to smaller components that are not specific to cell functions.
3. Organelle specifically refers to microscopic structures within a cell that each have specific roles.

Step 4: Verify and Summarize

Based on the definitions provided, the term that fits the description of a microscopic structure in a cell that carries out individual functions is Organelle.

Final Answer

Organelle
