Eukaryotic Cell Components

Front

What provides rigidity for the walls of the cell?

Back

Cellulose is a polysaccharide that forms the structural component of the cell wall in plants, providing rigidity and strength.

Front

What is the process called when materials pass through the membrane?

Back

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

Front

What does it mean when a cell membrane is described as semipermeable?

Back

A semipermeable membrane allows certain substances to pass through while blocking others, maintaining the internal environment of the cell.

Front

What is the term for the movement of water through a semipermeable membrane?

Back

Osmosis is the diffusion of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the main function of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates the movement of substances in and out of the cell.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes, such as energy production, protein synthesis, and waste processing.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration, providing energy for cellular activities.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the purpose of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.

Front

What is the function of the Golgi apparatus?

Back

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