Cells and Homeostasis Unit Review

Front

What is the function of the phospholipid bilayer in the cell membrane?

Back

It allows for selective permeability, enabling the cell to maintain homeostasis.

Front

How does the cell membrane contribute to homeostasis?

Back

It regulates the internal environment by controlling the entry and exit of substances.

Front

What is endocytosis?

Back

It is an active process that allows cells to intake large molecules and particles, aiding in homeostasis.

Front

What structure is found in eukaryotic cells but not in prokaryotic cells?

Back

Nucleus.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Front

Define selective permeability.

Back

The ability of a cell membrane to allow certain substances to pass while blocking others.

Front

What is homeostasis?

Back

The maintenance of a stable internal environment in an organism.

Front

What role do ribosomes play in a cell?

Back

They are responsible for protein synthesis.

Front

What is the plasma membrane made of?

Back

A phospholipid bilayer with embedded proteins.
