Cell Structure and Function

Front

Fluid portion of the cell outside the nucleus

Back

Cytoplasm: The jelly-like substance that fills the interior of a cell, providing a medium for chemical reactions and supporting cell structures.

Front

What is the primary structural component of the cell membrane?

Back

Lipids: Molecules that form the bilayer of the cell membrane, providing structure and regulating the movement of substances in and out of the cell.

Front

What is homeostasis in cells?

Back

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

Front

What happens to plant cells in hypotonic solutions?

Back

The central vacuole increases in size, causing the cell to swell and maintain turgor pressure.

Front

What are unicellular organisms?

Back

Unicellular organisms: Organisms made up of a single cell that can perform all life processes, including reproduction.

Front

What is protein synthesis?

Back

Protein synthesis: The process by which cells build proteins, involving transcription in the nucleus and translation at ribosomes.

Front

What structures are involved in protein synthesis?

Back

Ribosomes, rough endoplasmic reticulum, and Golgi apparatus are key structures involved in synthesizing and processing proteins.

Front

What is the function of the Golgi apparatus?

Back

Golgi apparatus: An organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of ribosomes?

Back

Ribosomes: Cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of the cell membrane?

Back

Cell membrane: A protective barrier that regulates what enters and exits the cell, maintaining homeostasis.
