The organization of the genetic material

The location of the cytoplasm

The role of the cell membrane

The function of the flagella

Active transport occurs only in cells that require large amounts of energy. Passive transport occurs in all cells.

Active transport requires ATP. Passive transport does not require ATP.

Active transport moves substances along the concentration gradient. Passive transport moves substances against the concentration gradient.

Active transport occurs in all cells. Passive transport requires ATP.

Passive transport

Simple diffusion

Active transport

Osmosis

By sexually reproducing with other viruses in the environment

By replicating inside the cell and then lysing the cell

By gaining energy from metabolizing their food

By competing for water with cells of the infected organism

A virus divides into two identical virus particles before infecting the host cell.

A virus enters a host cell and uses the materials from the host cell to produce new virus particles.

Multiple virus particles fuse and form a large particle that breaks apart, releasing new virus particles.

Multiple virus particles break down in component parts, which then reassemble into new copies of the virus.
