Seeds & Plant Growth
Observe and describe how seeds and bulbs grow into mature plants through stages of germination and growth
What a learner can do afterwards
- Describe the stages: seed absorbs water → root appears → shoot pushes up → leaves open
- Compare how a bulb and a seed start growing differently
- Record observations of a growing plant over several days using drawings or a simple diary

A seed looks like it is doing nothing, but it is not asleep. Give it water and warmth, and it wakes up. First it soaks up water. Then a tiny root pushes down into the soil. After that, a shoot pushes up toward the light, and finally leaves open up to catch the sun.
A bulb looks different from a seed. It already has food packed inside it, like a lunch box for the plant. A bulb still grows roots first, but its packed-up food helps the shoot grow fast.
Every day, Amir drew a picture of his bean plant in a notebook. On day 2 he drew a tiny root. On day 5 he drew a shoot poking out of the soil. On day 9 he drew two little leaves. His diary told the whole story of how the plant grew.
Keep your seed or bulb a little damp, not soaking wet, and check it at the same time each day. Small changes are easier to spot if you look often.
A seed soaks up water, then grows a root, a shoot, and leaves. A bulb grows roots first too, and the food stored inside it helps the shoot grow fast.

Exploring and explaining germination, growth and development
This booklet is all about watching a seed wake up and grow. First the seed rests and waits. When it gets water and warmth, it starts to grow. This waking up is called germination. A tiny root pokes out first and digs down into the soil. Then a little shoot pushes up toward the light. Leaves open at the top and start making food for the plant. The booklet gives you an activity for each stage, so you can plant fast-growing seeds and see every step with your own eyes. You can draw what you see each day and watch your seed become a real plant.
Blogpost - Teaching with the Fast Plants Life Cycle
Some plants grow very fast. They are called Fast Plants, and they are great for watching a plant's whole life. A Fast Plant seed can sprout in just a few days. First the seed soaks up water. Then a root comes out, then a shoot, then leaves. Soon the plant has flowers, and the flowers make new seeds. Then the cycle can start all over again. Because these plants grow so quickly, you can watch every stage yourself. You can keep a little diary with a drawing for each day and see how your plant changes from a tiny seed into a flowering plant.
Chapter Summary: Evolution of Seed Plants
A seed is like a tiny suitcase for a baby plant. Inside the seed there is a baby plant and a packed lunch of food to help it start growing. A tough coat on the outside keeps the baby plant safe and stops it from drying out. Seeds are also very patient. They can wait until the time is just right, with enough water and warmth, before they start to grow. When the conditions are good, the seed germinates. It takes in water, the coat softens, and a root and a shoot begin to grow. Long ago, seeds helped plants spread all over the land.
How to Plant & Grow Lemon Seeds into Delicious Citrus Trees
You can grow a lemon tree from a seed you find inside a lemon. First, pick a plump, healthy seed and rinse off the juice. Plant it in a small pot with soft, damp soil, about as deep as your fingernail. Keep the soil moist, like a wrung-out sponge, and put the pot somewhere warm and bright. Then wait. In a couple of weeks the seed germinates. A root grows down first, and then a little green shoot pushes up through the soil. Leaves open, and your seedling slowly grows. With water, light, and care, it can one day become a real lemon tree.
How to Grow Bamboo from Seed into Mature Plants
Growing bamboo from seed takes patience, but it is fun to watch. Start with fresh seeds from a good supplier. Soak the seeds in water so they can drink and wake up. Then plant them in little pots of damp soil and keep them warm. Soon the seeds germinate. A root slips down into the soil, and a thin green shoot reaches up. The seedlings need gentle light and moist soil every day. When they are bigger and stronger, they can move to a larger pot or a garden spot. Little by little, the small seedlings grow into tall bamboo plants.
