Seeds and Bulbs The first stage in the life cycle of most plants is a seed. Seeds come in all shapes and sizes. Every plant has a different seed.
Seeds and Bulbs Every single seed has the beginnings of a new plant inside it, along with a little store of food to help it grow. When the conditions are right, the seed soaks up water and swells, and the tiny new plant bursts out of its shell. This is called germination .

Planting Seeds Neve, my little girl, loves gardening. She is going to help us by planting some seeds so we can compare how they grow. You can do this too, but you don’t have to. Comparing means looking closely to see what is similar and what is different.
What Do Plants Need to Grow? Seeds need to wait for conditions to be just right before seeds can germinate and bulbs can sprout new growth. What do you think that our plants will need so they can sprout and grow well?
Planting Neve is going to plant some seeds and set up a comparative test . You can do this too. In our comparative test, Neve is going to plant the same seeds so we can compare how they grow under different conditions. This will help us to learn what plants need to grow well.
