What is the function of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

What is the Endosymbiotic Theory?

Back

The Endosymbiotic Theory suggests that mitochondria and chloroplasts originated as free-living bacteria that were engulfed by ancestral eukaryotic cells.

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process that uses proteins to help move substances across a cell membrane without the use of energy.

Front

What role do ribosomes play in a cell?

Back

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

Front

What is the rough endoplasmic reticulum (RER)?

Back

The rough endoplasmic reticulum is a type of endoplasmic reticulum studded with ribosomes, involved in the synthesis and processing of proteins.

Front

What is the smooth endoplasmic reticulum (SER)?

Back

The smooth endoplasmic reticulum is involved in lipid synthesis, detoxification, and calcium ion storage.

Front

What are lysosomes?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

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.

Front

What is osmosis?

Back

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