Biology Milestone Review Flashcardizz: Part II

Front

What is the fluid-mosaic model of the cell membrane?

Back

The fluid-mosaic model describes the structure of the cell membrane as a mosaic of various proteins that float in or on the fluid lipid bilayer, allowing for flexibility and movement.

Front

What is the primary function of proteins in the cell membrane?

Back

Proteins in the cell membrane allow substances to cross the plasma membrane via active transport.

Front

How do cell membranes and cell walls differ in function?

Back

Cell membranes function as selectively permeable gatekeepers, while cell walls provide structural support.

Front

What happens to plant cells when placed in a saltwater solution?

Back

The cells will shrink within the cell walls due to osmosis.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus sorts and packages proteins created by ribosomes for transport to their destinations.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.
