Here's the breakdown:
* Organ: An organ is a structure made up of different types of tissues working together to perform a specific function. For example, your heart is an organ made of muscle tissue, connective tissue, and nervous tissue.
* Tissue: A tissue is a group of similar cells that work together to perform a specific function. For example, muscle tissue is made up of muscle cells that contract to allow movement.
Cells are the basic building blocks of life. They are the smallest unit that can perform all the functions necessary for life.
Here's an analogy to help you understand:
* Imagine a house: The house represents the organism.
* The rooms in the house represent different organs (like the kitchen, bedroom, living room).
* Each room is built from different materials (like wood, brick, plaster) representing different tissues.
* The individual bricks and wood planks are like cells – the basic building blocks of the whole structure.
So, organs are made of tissues, which are made of cells.
