Cells and Cellular Processes Test Review

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles, such as mitochondria and endoplasmic reticulum.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that lacks a nucleus and membrane-bound organelles, and is typically smaller and simpler than eukaryotic cells.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to regulate the transport of substances in and out of the cell, maintaining homeostasis.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within eukaryotic cells that are enclosed by membranes, such as the nucleus, mitochondria, and Golgi apparatus.

Front

What is homeostasis in the context of cells?

Back

Homeostasis refers to the ability of a cell to maintain a stable internal environment despite changes in external conditions.

Front

What is the role of mitochondria in eukaryotic cells?

Back

Mitochondria are the powerhouses of eukaryotic cells, responsible for producing ATP through cellular respiration.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells are distinguished from eukaryotic cells by their lack of a nucleus and membrane-bound organelles.

Front

Can bacteria be classified as eukaryotic cells? Why or why not?

Back

No, bacteria are classified as prokaryotic cells because they do not have a nucleus or membrane-bound organelles.

Front

What is the significance of the cell membrane in maintaining homeostasis?

Back

The cell membrane's selective permeability allows it to control the movement of ions and molecules, thus helping to maintain the cell's internal balance.

Front

What are some examples of eukaryotic cells?

Back

Examples of eukaryotic cells include animal cells, plant cells, fungi, and protists.
