Most plants have flowers so they can make seeds. There is a new plant with a tiny root and shoot inside every seed. There is also some food for the new plant in the seed. A seed needs water and light so it can start to grow.
Plants need sunlight, soil and water to grow.
Once a seed has begun to sprout it usually needs soil, water and sunlight so it can grow from a seedling into a healthy plant. Some plants make new plants by sending out stems that grow roots and turn into new plants. The shoots they send out are called runners.
Tulips grow from a bulb.
Some new plants grow from bulbs or corms. An onion is a bulb. When a bulb first grows, the new plant gets energy from the leaves of the bulb.
Bean plants grow from a seed.
Seeds do not grow until the conditions are right. When a seed finds the right conditions, it will grow a root and a shoot. Some coconut palm seeds float out at sea for months before they reach a place to grow.
