Cell Structure and Function

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the need for energy input, relying on concentration gradients.

Front

What is the function of the Golgi body in a cell?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of vacuoles in a cell?

Back

Vacuoles are membrane-bound organelles that serve as storage compartments for various substances, including nutrients, waste products, and water.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells are generally smaller, lack a nucleus, and do not have membrane-bound organelles, while eukaryotic cells are larger and have a defined nucleus and organelles.

Front

What structures are typically found in prokaryotic cells?

Back

Prokaryotic cells typically contain a cell membrane, cell wall, ribosomes, and genetic material (DNA), but lack a nucleus.

Front

What is the primary difference between eukaryotic and prokaryotic cells?

Back

The primary difference is that eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, providing protection and structural support.

Front

What is the significance of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins based on the genetic code.

Front

What is the role of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and is responsible for regulating gene expression and cell division.

Front

What is the function of lysosomes?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.
