Final answer:
Organelles are specialized structures found within eukaryotic cells, each performing specific functions that are vital to the cell's operation, such as energy production and photosynthesis.
Step-by-step explanation:
organelles are small structures within a cell that have a specific job or function.
An organelle is a specialized structure encountered within the cytoplasm of a eukaryotic cell. Enclosed by a membrane, each organelle performs a critical function that contributes to the cell's survivability and operation. Take, for instance, the mitochondria and chloroplasts; they are instrumental in energy production and photosynthesis, respectively. While mitochondria generate the energy needed by the cell, chloroplasts enable plants to harness sunlight to create sugars. Unlike prokaryotic cells, eukaryotic cells have these membrane-bound organelles, including the nucleus, Golgi apparatus, and endoplasmic reticulum. This complex organization allows eukaryotic cells to perform more sophisticated functions compared to their prokaryotic counterparts.
An organelle is a structure within the cytoplasm of a eukaryotic cell that is enclosed within a membrane and performs a specific job. Organelles are involved in many vital cell functions. Examples of organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
In summary, organelles are small structures within the cell that have specific functions and are enclosed within a membrane.
