Some seeds are so tiny they look just like specks of dust. Others are as big as footballs! Most seeds do not start to grow as soon as they are made. They need to be kept safe inside a fruit or seed case until it is the right time to grow into a new plant.
Most seeds grow inside a seed case or fruit.
The casing that protects a seed can be hard like a nut shell, or soft like an apple or tomato. Each seed case is adapted to help keep the seed safe.
Beans and nuts are seeds.
Inside each seed is a baby plant. This tiny plant already has a root and shoot and the food it needs to begin to grow.
