  1. THINGS THAT GO AROUND

  2. All the stages of an organism’s life The Life Cycle of a Plant

  3. Seed: • Each seed contains a plant embryo. • Each seed contains food for the embryo. • The food helps the embryo survive during the time it cannot make its own food. • A tough outer case protects the embryo

  4. Germinate: • Seeds do not always germinate right away; they can wait for extensive periods of time to grow. • When a seed germinates, it begins to grow.A seed needs water, nutrients and the right temperature to grow.

  5. Seedling: • After the seed germinates, it grows into a young plant called a seedling. • It looks like its parent because of heredity.Color and size (height and weight) are examples of heredity.

  6. Stages of the Life Cycle: • Seeds germinate into a plant. • The plant grows, develops, reproduces and then dies.

  7. Flowering Plants sunflower, tulips, marigold,lily, jasmine, rose,lotus,hibiscus, Petunia,daisy,water lilies Conifers pine, fir, spruce, evergreen How Are Seeds Made?

  8. Female parts: Male parts: -- makes the eggs that -- makes pollen, which is become seeds. the powdery material that is needed by the eggs to make seeds. Eggs + Pollen = Seeds FLOWERING PLANTS

  9. FLOWERING PLANTS Eggs + Pollen = Seeds Wind Insects (bees/birds) Animals Nectar = sugary liquid in flowers. While the animals drink the nectar, pollen rubs off on their bodies. When they move to other flowers, some of the pollen is transferred to female flower parts.

  10. Life Cycle of a Flowering Plant

  11. Conifers • Some plants do not have leaves; they have needles or brushes. • There are two kinds of cones: ***small pollen cones ***large seed cones Wind blows pollen from small to large cone. Pollen + large cone = Seed

  12. Pollen + large Conifer Cone = Seed • Seed grows inside a large cone. • When seeds are ripe, they fall to the ground. • Each seed has the ability to germinate and eventually grow into a tree.

  13. Life Cycle of a Conifer

  14. What Other Ways Do Plants Reproduce? • Seeds • Cuttings: pieces of the plant that was cut off from the original. When placed in water, new roots will grow. (i.e., perennials such as salvias, geraniums, asters and dianthus, as well as roses, heathers, hydrangeas and more)

  15. What Other Ways Do Plants Reproduce? • Bulb: an underground stem (i.e., onion) • Tuber: an underground stem (i.e., potato)

  16. What Other Ways Do Plants Reproduce? • Spores: not as tough as seeds and does not have a food supply but if it gets light, water, and nutrients, it can grow into a new plant. (i.e., mosses and ferns)
