Cell Organisation Flashcards
Large Multicellular Organisms are made up of [ ]
Organ systems
What kind of cells carry out a particular function?
Specialised cells
What is the process by which cells become specialised?
Differentiation
When does Differentiation take place?
During the DEVELOPMENT of a multicellular organism
Specialised cells form [ ], which from [ ], which form [ ]
Tissues
Organs
Organ systems
Large Multicellular Organisms (eg. Humans) have different systems inside them for [ ] and [ ] materials
Exchanging and Transporting
Similar Cells are organised into [ ]
Tissues
What is a tissue?
A group of SIMILAR CELLS that work together to carry out a particular FUNCTION
Tissues can include [ ] type of cell
More than one
What does MUSCLE tissue do?
It contracts to move whatever it is attached to
What does GLANDULAR tissue do?
It makes and secretes chemicals like enzymes and hormones
What does EPITHELIAL tissue do?
Covers some parts of the body, eg. inside the gut
Tissues are organised into [ ]
Organs
What is an organ?
A group of different tissues that work together to perform a certain function
What does MUSCLE tissue do in the STOMACH?
Moves the stomach wall to CHURN UP THE FOOD
What does GLANDULAR tissue do in the STOMACH?
Makes digestive juices to digest food
What does EPITHELIAL tissue do in the STOMACH?
covers the outside and inside of the stomch
Organs are organised into [ ]
Organ systems
What is an organ system?
Give an example
A group of organs working together to perform a particular function. For example, the digestive system breaks down food
What do Glands do in the digestive system?
(Eg, pancreas and salivary glands) produce digestive juices
The [ ] and [ ] break down food in the digestive system
Stomach
Small Intestine
What do Liver do in the digestive system?
Produces bile
What does the Small Intestine do in the digestive system?
Absorbs soluble food molecules
What does the Large Intestine do in the digestive system?
Absorbs water from undigested food, leaving faeces
The [ ] system exchanges materials with the environment by taking in [ ] and releasing substances such as [ ]
digestive
nutrients
bile
