Animal: Moose (Multicellular); Plant: Tree (Multicellular); Fungi: Mushroom (Multicellular); Protist: Algae (Can be Unicellular or Multicellular); Bacteria: E. coli (Unicellular)

difference between Unicellular and Multicellular organisms

Unicellular organisms are made of one cell, while Multicellular organisms are made of many cells.

Gas Exchange?

Oxygen diffuses into the cell and carbon dioxide diffuses out.

unicellular organisms respond to their environment?

They detect changes using methods like sensing chemicals or light, instead of 5 senses like humans.

Define Movement

Name the 5 Organ Systems.

Circulatory, Respiratory, Digestive, Musculoskeletal, and Nervous Systems.

Circulatory System? purpose

To transport nutrients, gases, and wastes to and from cells.

Respiratory System? pursose

To exchange oxygen and carbon dioxide between blood and the external environment.

Digestive System? purpose

To break down food into small particles (nutrients) that can be transported to all cells.

Musculoskeletal System? purpose

To provide structure/support, protect internal organs, and enable movement/locomotion.

Nervous System? purpose

To respond to changes in the body's environment and coordinate the functions of all other organ systems.
