Cells and Cell Theory

Front

What is a eukaryote?

Back

A eukaryote is a type of cell that has a nucleus and organelles, such as mitochondria and chloroplasts. Examples include plant and animal cells.

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles. Bacteria are examples of prokaryotic cells.

Front

What organelles are found in eukaryotic cells?

Back

Eukaryotic cells contain organelles such as the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, and Golgi apparatus.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What do all cells have in common?

Back

All cells have a plasma membrane, cytoplasm, ribosomes, and DNA.

Front

What is a plasma membrane?

Back

The plasma membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site of many cellular processes.

Front

What are ribosomes?

Back

Ribosomes are molecular machines in cells that synthesize proteins by translating messenger RNA.

Front

What is the total magnification if the ocular lens is 10X and the objective lens is 40X?

Back

The total magnification is 400X (10X ocular lens multiplied by 40X objective lens).
