Cells produce new cells of the same kind through cell division.

Front 2

Development

Growth, in the biological sense, is not merely characterized by a literal increase in girth. It also refers to the irreversible increase in the number of cells. A multitude of cell division will change an organism's form from a simple to complex one.

Movement

Back 3

To better interact with its environment and have a higher chance of surviving, a cell must be able to change its physical position.

Front 4

Responsiveness

Back 4

Cells react accordingly when they encounter other organisms or objects in their environment.

Front 5

Metabolism

Front 8

Presence of genes

Back 8

All lifeforms contain information in the form of genes that allow them to pass on their physical traits to their offspring.

Front 9

Evolution

Back 9

Cells with better adaptations with respect to their environment will have a higher chance of surviving.

All plants are made up of cells

Front 11

Theodor Schwann

Back 11

every animal is composed of cells and products of cells

Front 12

Robert Remak

Back 12

claimed that all cells arise from pre existing cells through cell division

Front 13

Rudolf Virchow

Back 13

popularized the Latin phrase "omnis cellula e cellula"
