Characteristics of Living Things

Characteristics of Living Things

1. Growth and Development

Living things grow and develop over time. This means they start small and become bigger and more complex as they age. For example, a baby plant starts as a tiny seed and grows into a tall tree with branches and leaves. Similarly, a baby animal grows into an adult with more strength and abilities.

Think of growth like building a tower with blocks. You start with just one block and keep adding more until you have a tall tower. Living things do the same thing, but with their bodies.

2. Reproduction

Living things can make more of their own kind. This process is called reproduction. Plants make seeds, and animals have babies. For example, a cat can have kittens, and a flower can produce seeds that grow into new plants. This ensures that the species continues to exist.

Imagine reproduction like making a copy of a drawing. You draw one picture, and then you make another one just like it. Living things do this to make more of themselves, just like you make more drawings.
