How a seed grows• A seed needs a warm, moist place.• The seed needs water and food.• The embryo will push through the seed coat with the roots and stem.
The RootsThe roots reach down into the ground or
water to feed the seed.
The roots act like a straw, absorbing nutrients and sending the food to the stem, leaves and flowers.
The Stem
The stem carries nutrients from the roots to the leaves.
The Leaves
The leaves take in sunlight, water and carbon dioxide to feed the plant.
