Flashcards in Organisation of cells Deck (5)
- A tissue is made up of a collection of differentiated cells that have a specialised function or functions.
- So, each tissue is adapted for a particular function within the organism.
Categories of tissues in animals
- Nervous tissue: adapted to support transmission of electrical impulses
- Epithelial tissue: adapted to cover body surfaces, internal and external.
- Muscle tissue: adapted to contract.
- Connective tissue: adapted either to hold tissues together or as a transport medium.
Categories of tissues in plants
- Epidermis tissue: adapted to cover plant surfaces.
- Vascular tissue: adapted for transport of water and nutrients.
- An organ is a collection of tissues that are adapted to perform a particular function in an organism.
- Large multicellular organisms have coordinated organ systems.
- Each organ system is composed of a number of organs working together to carry out a major function in the body.
