Characteristics of animals

1. Animals are multicellular organisms, meaning they are made up of more than one cell.

2. Animals are eukaryotic, meaning their cells have a nucleus and other membrane-bound organelles.
3. Animals are heterotrophic, meaning they cannot produce their own food and rely on consuming other organisms for energy.
4. Animals have specialized sense organs that allow them to perceive and respond to their environments.
5. Animals have the ability to move, either through locomotion or in the case of sessile animals, through growth or expansion.
6. Animals reproduce sexually, with the fusion of sperm and egg cells to produce offspring.
7. Animals have a diverse range of body plans and adaptations for different environments, including adaptations for swimming, flying, and living on land.
8. Animals have a hierarchical organization, with specialized cells forming tissues, tissues forming organs, and organs working together to form organ systems.
9. Animals have the ability to learn and exhibit complex behaviors, varying in complexity across different species.
10. Animals have the capacity for growth and development, with distinct life stages from birth to maturity.
