Cell Organelles and Transport

Front

What is Active Transport?

Back

Active Transport is the movement of molecules from an area of low concentration to an area of high concentration, requiring energy (ATP).

Front

What is Passive Transport?

Back

Passive Transport is the movement of molecules across a cell membrane without the use of energy, moving from high to low concentration.

Front

What happens to a cell in a hypotonic solution?

Back

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

Front

What are Ribosomes responsible for?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is the function of Vacuoles in plant cells?

Back

Vacuoles hold and store water, nutrients, and waste products; they are larger in plant cells compared to animal cells.

Front

What is the role of the Golgi Body?

Back

The Golgi Body 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 molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the function of the Cell Membrane?

Back

The Cell Membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the difference between Endocytosis and Exocytosis?

Back

Endocytosis is the process of taking substances into the cell, while Exocytosis is the process of expelling substances from the cell.

Front

What is ATP and its role in Active Transport?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, providing the energy needed for Active Transport.
