Cell Organelles & Transport Review

Front

Diffusion of water through a selectively permeable membrane

Back

Osmosis is the process by which water molecules move through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Which organelle contains genetic material?

Back

The Nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is the function of the vacuole?

Back

The vacuole is a sac that stores water, nutrients, and waste products, helping to maintain turgor pressure in plant cells.

Front

This organelle modifies, sorts and packages proteins and other molecular products from the ER for storage or release out of the cell.

Back

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

Front

The site of photosynthesis

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy in the form of glucose.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

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 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.
