Cell Structure and Function (MODIFIED)

Front

What is the function of the cell membrane?

Back

The cell membrane is flexible and regulates what enters and leaves the cell, helping to maintain homeostasis.

Front

What is the hydrophobic region of the cell membrane?

Back

The hydrophobic region of the cell membrane is the part that does not like water, typically represented by the fatty acid tails of phospholipids.

Front

True or False: Stem cells can give rise to many types of specialized cells.

Back

True

Front

What represents the polar head of the cell membrane?

Back

The polar head of the cell membrane is hydrophilic and likes water, typically represented by the phosphate group in phospholipids.

Front

Which organelle is known as the cellular highway?

Back

The endoplasmic reticulum is known as the cellular highway because it transports and synthesizes lipids and some proteins.

Front

What is the primary role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is homeostasis in the context of cell function?

Back

Homeostasis is the process by which cells maintain a stable internal environment despite changes in external conditions.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to the cell, primarily found in plant cells.

Front

What is the role of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
