1101 - What is the hierarchical structure of living organisms, from cells to organs to individuals?

Imagine a building with many levels. Here's how living things are organized:

1. Cells: The smallest unit, like a single brick. All living things are made of one or more cells.
2. Tissues: Cells work together to form tissues, like a wall made of bricks.
3. Organs: Tissues work together to form organs, like a room made of walls and a floor.
4. Organ Systems: Organs work together to form systems, like a house made of many rooms.
5. Organism (or Individual): All the systems work together to form a single living thing, like a person or an animal.

This is how our bodies are organized, and it helps us understand how all living things are connected.
