Structure and Function in Living Organisms Flashcards
What are cells?
Units that make up a living organism.
Cells make tissues.
Cells have structures that are specialised so that they can carry out their function.
What is a tissue made up of?
A group of cells with a similar structure and function.
What is an organ made up of?
Made up of tissues- often different tissues.
Organs have a particular job to do e.g. the heart circulates the blood.
What is an organ system?
Groups of organs working together that carry out a particular function, e.g. digestive system.

How many organ systems make up the main plant organs that allow life processes to take place?
4
- flower (reproduction, move)
- stem (nutrition, excretion, growth)
- leaves (nutrition, excretion)
- roots (nutrition)
All parts are sensitive to the surroundings, every cell respires.
