Cells and Cell Transport

Front

What is the function of vesicles in a cell?

Back

Vesicles are small membrane-bound sacs that transport materials within the cell, such as proteins and waste.

Front

What is the nucleolus and its role in the cell?

Back

The nucleolus is a structure within the nucleus responsible for producing ribosomes.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf external substances, bringing them into the cell.

Front

What is diffusion?

Back

Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

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.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins and lipids and the transport of materials within the cell.

Front

What is the purpose of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the plasma membrane?

Back

The plasma membrane is a selective barrier that regulates what enters and exits the cell.
