What are the three main components that all cells, regardless of whether they are prokaryotic or eukaryotic, have in common?

All cells have a cell membrane, cytoplasm, and DNA.

Which of the following is NOT a characteristic of prokaryotic cells?

They contain membrane-enclosed organelles.

Describe the function of the Golgi apparatus in a cell.

The Golgi apparatus receives proteins and other materials from the endoplasmic reticulum and customizes them into usable forms by folding them or adding lipids/carbohydrates.

What is the role of lysosomes within a cell, and what do they contain to perform this role?

Lysosomes are the garbage collectors of the cell, breaking down damaged or worn-out cell parts using enzymes.

Explain the difference between rough endoplasmic reticulum (ER) and smooth endoplasmic reticulum (ER).

Rough ER has ribosomes attached to it, which are involved in protein synthesis, while smooth ER does not have ribosomes and is involved in other functions like lipid synthesis.

Key concepts students will learn:

•
All cells have a cell membrane, cytoplasm, and DNA in common, no matter their type.
•
Eukaryotic cells have a nucleus and other specialized parts called organelles, while prokaryotic cells do not have a nucleus or membrane-enclosed organelles.
•
The nucleus contains DNA, which dictates what the cell will do, and the mitochondria is the powerhouse of the cell, creating energy in the form of ATP.
