Plants And Seeds 1) A seed is a plant ready to grow. 2) All seeds grow into the same kind of plant that made them. 3) Seeds rest inside a snug coat waiting to burst out. Plants And Seeds 1) Seeds are different shapes, sizes, and colors. 2) Many plants grow flowers. 3) Flowers are where most seeds begin. 4) Seeds need water, air, and warmth to grow. Plants And Seeds Germinating 1) Water soaks into the hard coats, and the seeds swell up and the coat splits open. 2) Tiny roots start to grow downwards. 3) Tiny shoots start to grow upwards. 4) The seeds are germinating. Seeds need water, air, light and good soil. 1) When seeds germinate they need food. 2) Seeds get their food from water and the soil. 3) Germinating seeds need warmth, light, and they need air to breathe. 4) They breathe through their leaves and their roots. Minerals, Water, Pollination 1) The seeds take in minerals and water through the roots. 2) The stem carries the minerals and water to the leaves. 3) Next Pollination occurs in different ways. The wind, bees, insects, and birds help to pollinate plants. Pollination 1) Before a seed can grow, a grain of pollen from the stamen must land on the stigma at the top of the pistil of a flower like itself. That’s pollination. 2) If a pollen grain from a flower lands on the pistil of the same kind of flower, it grows a long tube through the pistil into an ovule. This is the beginning of a seed. Seeds grow inside the flower 1) Seeds grow inside the flower even as the flower begins to die. 2) As the seeds become bigger, a fruit or pod grows around them. 3) The fruit or pod protects the seed. How some seeds travel 1) When the fruit or pod ripens, it breaks open. 2) The seeds are ready to become new plants. 3) Some seeds fall to the ground, birds eat berries and seeds fall out, and other seeds fall into streams, ponds, rivers and oceans. Animals help scatter seeds 1) Animals help to scatter seeds too. 2) They hide acorns and nuts in the ground. 3) Some seeds have hooks that stick to the fur of animals or people’s clothes later to drop onto the ground. Seeds are planted for flowers, vegetables and fruit 1) Seeds are planted for flowers, vegetable and fruit gardens. 2) Seeds can come in small envelopes or boxes from the store. 3) People can save some seeds from the year before that they were able to collect. We need plants and seeds for our life. 1) We need plants. They make clean air for us to breathe. 2) We need to be kind to plants and take good care of them. 3) We could not live without them!
