Cells Organisation
- Large Multicelluar Organism
- Large Multicelluar Organism
are made up of Organ
Systems
- The process that cell become
specialised for a particular job
is called 'Differentiation
function'
- Differentiation occurs
during the development of a
multicelluar organism
- Specialised Cells form tissue
- Then form organs
- And then form organ system
- Large multicelluar organism have differnt systems
inside them for exchanging and transporting
material
- Diagram of Cell Organisation
- Similar Cells are organised into Tissues
- A Tissues is a group of similar cells working
together carrying out a particular function. It
can include more than one types of cells
- In Mammals, Example of tissues are:
- 1. Muscular Tissue
- Which Contracts (shorten) to
move what it's attached to
- 2. Glandular Tissue
- Which makes and secretes chemicals
like enzymes and hormones
- 3. Epithelial Tissue
- Which covers some part of
the body
- E.g The inside of the gut
- Tissues are organised into organs
- An organ is a group of different tissues that
work together to perform a certain function.
- For Example, the stomach is a organ that
made up of these tissues:
- 2. Glandular Tissue
- which makes digestive
juices to digest food
- 3. Epithelial Tissue
- which cover the inside
and outside of the
stomach
- 1. Muscular Tissue
- which move the
stomach wall to chum
up the food
- Organ are organised into organ systems
- A organ sytem is a group of organs
working together to perform a
particular function.
- For Example, the digestive system breaks
down food and is made up of these organs
- 1. Glands
- Produces digestive juices
- 2. The Stomach
- Digest food
- 3. The Liver
- produces bile
- 4. Small intestine
- Digest food
- Absorbs soluble food molecules
- 5. Large intestine
- Absorbs water from undigested food
