Cell Structure and Function

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

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

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

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.

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

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

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

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

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

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