Verified step by step guidance1
Understand the definition of a eukaryote: Eukaryotic cells are characterized by having a true nucleus enclosed in a nuclear membrane and various membrane-bound organelles.
Identify the key features of eukaryotic cells: These include the presence of a nucleus, organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and sometimes chloroplasts in plant cells.
Differentiate between eukaryotic and prokaryotic cells: Prokaryotic cells, such as bacteria, do not have a nucleus or membrane-bound organelles and often reproduce through binary fission.
Evaluate the given options: Look for the option that mentions the presence of a nucleus and membrane-bound organelles, which is a defining feature of eukaryotic cells.
Select the correct description: Choose the option that accurately describes a eukaryotic cell as having a nucleus and membrane-bound organelles.
