    Seeds by the Window

    One group received water and warmth, while another group stayed in a cooler place. The warm seeds opened first and sent pale roots downward along the glass. A few days later, green shoots turned toward the light from the window. The comparison showed that moisture, warmth, and light influence early plant growth.

    A.Ancient markets helped people trade goods and exchange information.
    B.A simple comparison reveals the conditions that help seeds begin to grow.
    C.A seed grows step by step when water, warmth, soil, and light support it.
    D.A wetland supports different animals whose activity changes through the morning.
