Question 1

What is Cellular Organisation

Answer 1

Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
The organization of cells is called a hierarchy which means they become more complex at each level.

Question 2

Describe the Cell Hierarchy

Answer 2

Cell (The smallest unit of life) > Tissue (Cell of the same type working together) > Organ (Tissue of different types working together) > Organ System (Multiple organs working together) > Organism (Multiple systems working together)

Question 3

What is cellular respiration

Answer 3

-Cells need energy to function
-Cells get their energy from transformation of glucose into usable energy, also known as ATP
-This occurs through a process called cellular respiration

Question 4

What is the cellular respiration equation

Answer 4

Glucose + Oxygen > Co2 + Water + ATP (energy)

Question 5

What does cellular respiration require?

Answer 5

-Glucose is obtained by the digestive system
-Oxygen is obtained by the respiratory system
