2.1: Levels of Organisation Flashcards
Are the cells the building blocks for all living organisms?
Yes
How many cells are Unicellular organisms made of
One
How many cells are multicellular organisms made of
A collection of cells (several)
In complex multicellular organisms: Cells are s...... to carry out particular functions These s...... cells form tissues The tissues form o...... The o........ form o.... systems
Cells are specialized to carry out particular functions
These specialized cells form tissues
The tissues form Organs
The organs form organ systems
In humans, the digestive system (provides the body with ……… )
In humans, the digestive system (provides the body with nutrients)
the respiratory system (provides the body with …… and removes …… ……..)
and the respiratory system (provides the body with oxygen and removes carbon dioxide)
In humans, the d………. system and the r……… system are examples of o…. s…. that provide dissolved materials that need to be moved quickly around the body in the blood by the ……. system
In humans, the digestive system and the respiratory
system are examples of organ systems that provide dissolved materials that need to be moved quickly around the body in the blood by the circulatory system
Organelles: A Co…….. within a c… that carries out a specific t…
Organelles: A Component within a cell that carries out a specific task
Cells: Basic f……. and s…….. units in a living ……
Basic Functional and Structural units in a living organism
Tissues: A group of c…. of similar structures working together to perform a particular f……
Tissues: A group of cells of similar structures working together to perform a particular function
Organs: Made from a g…. of different t…… working together to perform a particular f……..
Made from a group of different tissues working together to perform a particular function
Organ Systems: Made from a g….. of o….. with related functions, working together to p…… body functions within an o…….
Organ Systems: Made from a group of o.rgans with related functions, working together to perform body functions within an organism

Pancreas
What is needed to cure Poor Vision
Cornea
What is needed to cure hepatitis
Liver
What is needed to cure a coronary failure

Lung
What is the role of the liver in digestion (3 answers)
Produces Bile
Which raises the pH in the duodenum so enzymes can work at their optimum temp
And Emulsifies fat
