Unit 3 Master Review Game

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a semipermeable membrane through protein channels called aquaporins.

Front

What occurs during cytokinesis?

Back

Cytokinesis is the process where the cell splits at the cleavage furrow to form two identical daughter cells.

Front

What is a key statement of the cell theory?

Back

A key statement of the cell theory is that all organisms are composed of one or more cells.

Front

What is active transport?

Back

Active transport is the movement of molecules against their concentration gradient, requiring energy in the form of ATP.

Front

What does PMAT stand for in cell division?

Back

PMAT stands for Prophase, Metaphase, Anaphase, and Telophase.

Front

What is the role of aquaporins in cells?

Back

Aquaporins are protein channels that facilitate the transport of water across cell membranes.

Front

Define passive transport.

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What happens during prophase?

Back

During prophase, chromosomes condense and become visible, and the nuclear envelope begins to break down.

Front

What is the significance of the cleavage furrow?

Back

The cleavage furrow is the indentation that begins the process of cytokinesis, leading to the separation of the two daughter cells.

Front

Explain facilitated diffusion.

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move molecules across the cell membrane.
