THE 5 KINGDOMS OF LIVING THINGS THE CELL A cell is the smallest living unit that makes up a living thing. The cells in most animals and plants are specialised, so that they are able to work together and share the processes of life. Tissues consist of cells that carry out similar functions. Organs contain different types of tissue which work together to perform a particular funtion. Organ systems contain different organs. A group of organ systems working together form an organism. Unicellular organisms → just one single cell that perfoms the three vital functions (nutrition, reproduction, interaction). Multicellular organisms → with many different cells that carry out different functions.
The cell performs the three vital functions NUTRITION: nutrients --> Energy --> grow and development
INTERACTION: stimulus (senses) --> response REPRODUCTION: to produce new organisms. Asexual or sexual. Comments are closed.
