Roots
Roots anchor a plant and absorb water and mineral nutrients from the soil. Some roots also store food.

Plant a seed of curiosity! Discover how seeds germinate, how roots and leaves work, how plants make food, and how pollinators help gardens thrive. Includes interactive challenges, a growing journal, and free printable activities.
Different plant parts have different jobs. Together they help a plant take in water, make food, grow, reproduce, and survive.
Roots anchor a plant and absorb water and mineral nutrients from the soil. Some roots also store food.
The stem supports leaves and flowers. Tiny transport tissues move water, minerals, and sugars through many plants.
Leaves capture light for photosynthesis. Tiny openings called stomata allow gases such as carbon dioxide and oxygen to move in and out.
In flowering plants, flowers contain reproductive structures. Pollination can help pollen reach the part of a flower that can produce seeds.
Many fruits develop from flowers and contain seeds. Fruits can help protect seeds and sometimes help them spread to new places.
A seed contains a young plant and a supply of stored food in many species. With suitable conditions, it may germinate and begin growing.
Photosynthesis is the process many plants use to turn light energy into chemical energy stored in sugars.
Chlorophyll, a green pigment in many leaves, helps capture light energy.
Roots absorb water, which moves through the plant to the leaves and other parts.
Leaves take in carbon dioxide from the air through tiny openings called stomata.
Light + Water + Carbon dioxide → Sugars + Oxygen
This is a simplified summary. Plants use the sugars for energy and growth, and oxygen is released during photosynthesis.
Many seeds need water, oxygen, and a suitable temperature to germinate. Light requirements vary by species; after germination, seedlings usually need light to grow well.
Water enters a dry seed and helps start the processes that allow the embryo to grow.
A germinating seed needs oxygen for respiration, which releases energy from stored food.
Seeds germinate best within a temperature range suited to their species. Too cold or too hot can slow or prevent germination.
With an adult, place a few dry beans on a damp paper towel inside a clear container. Keep the towel damp, not flooded, and observe once a day. Record when the seed coat splits and a root appears. Do not eat seeds used in experiments, and wash hands afterwards.
Use seeds intended for growing or a safe classroom activity. Avoid mouldy materials and discard the experiment if mould develops.
Change the conditions in this learning model. It is a simplified prediction tool, not a guarantee of how a real seed will behave.
Use this journal while growing a plant at home or in class. The entries can be printed, but they are not saved online.
Ten questions on plant parts, photosynthesis, germination, and pollination, with instant explanations.
Which plant part absorbs water from the soil?
Open a print-friendly activity page, then print it or save it as a PDF. No account is required.
Record daily changes as a seed absorbs water and begins to sprout.
Practise identifying roots, stem, leaves, flowers, fruit, and seeds.
Track a plant's height, leaves, conditions, and changes over time.
If a worksheet does not open, allow pop-ups for your website.
Small observations can introduce scientific thinking, patience, measurement, and responsibility.
Encourage children to draw what they see before explaining it. Record changes rather than guessing what caused them.
Measure plant height at the same time of day and compare observations. Change one condition at a time for a clearer experiment.
Supervise tool use, wash hands after handling soil, avoid unknown plants and mushrooms, and never eat a plant unless a trusted adult confirms it is safe.
No. Light requirements vary by plant species. Many seeds can germinate in darkness if they have suitable moisture, oxygen, and temperature. After sprouting, seedlings usually need light to grow well.
Often, yes. A suitable pot on a bright windowsill or a safe outdoor container can work for some herbs and other plants. Choose a plant suited to the available light and climate.
Possible reasons include an old or non-viable seed, unsuitable temperature, too little water, waterlogging, or low oxygen. Different species also have different germination needs.
Yes. The seed-condition model, growing journal, quiz, and three browser-generated worksheets are included on this page.
