Cell Organisation Flashcards
Organisation (12 cards)
What are cells?
Cells are the basic building blocks that make up all living organisms.
Cells are essential for the structure and function of living beings.
What is the process by which cells become specialised for a particular job?
Differentiation.
Differentiation occurs during the development of a multicellular organism.
What do specialised cells form?
Tissues.
These tissues then form organs, which form organ systems.
What is a tissue?
A tissue is a group of similar cells that work together to carry out a particular function.
Tissues can include more than one type of cell.
What are examples of tissues in humans?
- Muscular tissue
- Glandular tissue
- Epithelial tissue
What is an organ?
An organ is a group of different tissues that work together to perform a certain function.
For example, the stomach is an organ made of muscular, glandular, and epithelial tissues.
What tissues make up the stomach?
- Muscular tissue
- Glandular tissue
- Epithelial tissue
What is an organ system?
An organ system is a group of organs working together to perform a particular function.
For example, the digestive system consists of various organs that work together to digest food.
What are the organs that make up the digestive system?
- Glands (e.g. pancreas and salivary glands)
- Stomach
- Small intestine
- Liver
- Large intestine
Which organ produces bile?
The liver.
Bile is important for digesting fats.
What is the role of the small intestine?
The small intestine absorbs soluble food molecules.
This is a critical step in the digestive process.
True or False: Organ systems work independently of each other.
False.
Organ systems work together to make entire organisms.
