Front

What are eukaryotes?

Back

Eukaryotes are complex cells that contain a nucleus and other membrane-bound organelles.

Front

How does a cell maintain homeostasis?

Back

A cell maintains homeostasis by regulating what enters and leaves the cell.

Front

Define plasma membrane.

Back

The plasma membrane is a flexible boundary of a cell that separates the cell from its surroundings.

Front

What is a monomer?

Back

A monomer is a building block for polymers.

Front

Explain the structure of the cell membrane.

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, allowing selective permeability.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is selective permeability?

Back

Selective permeability is the ability of the cell membrane to allow certain substances to pass while blocking others.

Front

What are the main components of the cell membrane?

Back

The main components of the cell membrane are phospholipids, proteins, cholesterol, and carbohydrates.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, act as receptors, and provide structural support.

Front

What is the fluid mosaic model?

Back

The fluid mosaic model describes the cell membrane as a flexible layer made of lipid molecules with proteins embedded in it.
