Bean seeds need sunlight to grow!

Hypothesis

My hypothesis is that ‘Bean seeds need sunlight to grow’. I am about to tell you almost everything there is to know about my hypothesis.

What I found

The first thing I need to tell you is that bean seeds are manly used in cooking but some can be used to treat illnesses like the Azuki which can help the kidney and other illnesses.

Most Bean and seeds are grown in the soil but you can actually grow seeds hydroponically which is growing them in water and other places other than the soil.

I have found out that to grow bean seeds it usually takes 7-10 days to germinate (sprout) but some can take less time.

In my Science Symposium I need to find out what other things the seeds need to grow and why they need them. Seeds need the sun to make food to grow. They also need the sun to create chlorophyll which makes the leaves green.

Seeds also need soil to provide the right nutrients for them and the soil holds the roots in place so the seed will grow.

Seeds need water because it helps the roots of the bean seed to break through the soil.
