What is osmosis?

Back

Osmosis is the process involving the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the function of the cytoskeleton?

Back

The cytoskeleton supports cell structure and drives cell movement, composed of microfilaments, microtubules, and centrioles.

Front

What is the primary function of ribosomes?

Back

The primary function of ribosomes is to synthesize proteins.

Front

How does the structure of the cell membrane contribute to its function?

Back

The fluid mosaic model of the cell membrane allows for flexibility and selective permeability, regulating the internal environment of the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process where substances move across a cell membrane with the help of transport proteins, such as glucose transport.

Front

Define diffusion.

Back

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

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What role do microtubules play in the cell?

Back

Microtubules are part of the cytoskeleton and help maintain cell shape, enable cell movement, and facilitate intracellular transport.

Front

What is the role of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins and lipids, and it plays a role in the transport of these molecules 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.
