Cell Biology Review

Front

What is the cell theory?

Back

The cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Who proposed that all plants are made of cells?

Back

Matthias Schleiden proposed that all plants are made of cells.

Front

What is the function of vesicles in a cell?

Back

Vesicles are membrane-bound sacs that transport materials within the cell and to the cell membrane for secretion.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is the difference between a hypotonic and hypertonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, while a hypertonic solution has a higher concentration of solutes.

Front

What is the role of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to plant cells and helps maintain their shape.

Front

What is osmosis?

Back

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

Front

What is the significance of equilibrium in cellular processes?

Back

Equilibrium in cellular processes means that the concentration of molecules is equal on both sides of a membrane, but molecules can still move across the membrane.

Front

What are organelles?

Back

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

Front

What is the primary function of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.
