Fertilization is fision process of ovum with sperm inside pistil. Based on its formation,fruit is divided into two kind, those are true fruit and false fruit.

Buahsejatiditemukanpadabuahpepaya, durian, mangga, tomat, dansebagainya. Based on its formation,fruit is divided into two kind, those are true fruit and false fruit. True fruit is fruit that is formed by all tissue in ovary. The fruit is found in fruits of papaya,durian,mango, tomato, and soon.

False fruit is fruit that is formed not only from its ovary, but also comes from another parts of the flower. The example are mangosteen, mede guava, ground cherry, and jackfruit. Mede guava its fruit comes from enlarging flower stalk. Jackfruit, its fruit comes from sepal that grows thicken and has meat.

Seed is formed from fertilization product that happens inside ovary. Ovary is separated into two, those are ovule packed by fruit leaves, such as seeds of mango, rambutan, salak, and ovule that is not packed by fruit leaves, such as seed of pakishaji (cycasrumphii).

Embryo consists of three parts, rootlet (radicle), little stalk (cauliculus), and seed leaf (cotyledon). Culiculus and leaf seed are called plumule.

  9. Reproduce– it means “to make more of the same kind” Plants reproduce differently

  10. How Seeds Form • After fertilization the flower dries up and petals fall off, leaving just the pistil and its ovary. • The top of the pistil falls off and the ovary gets larger as one or more seeds form inside it. • When the seeds are formed, the ovary dries up and the seeds fall out. • Corn, Beans, and Peas are seeds that we eat

  11. How Fertilization Occurs • When a pollen grain reaches a pistil, it grows a thin tube to the ovary. Sperm from the pollen grain combines with an egg, and a seed forms. Fertilization – the combination of sperm from a pollen grain with an egg to form a seed

  12. How Pollination Occurs • Butterflies may carry pollen from the stamen of one flower to the pistil of the the same flower. Sometimes the butterfly may carry pollen from the stamen of one flower to the pistil of another flower of the same kind. • Pollen: Nothing to Sneeze At Pollination- the movement of pollen from a stamen to a pistil

  13. Some flowering plants are monocot seed – a seed that has one seed leaf and stored food outside the seed leaf dicot seed – a seed that has two seed leaves that contain stored food

  14. What is the Life Cycle of a Flowering Plant dormant – the resting stage of a seed • Dormant Seed • Takes in water and the seed coat gets soft. If the seed has enough oxygen and the right temperature, it will begin to germinate.

  15. Seedling • When the stored food within the original seed leaves is used up, they dry up and drop off. More leaves grow from buds on the stem as the plant grows taller. The new leaves can trap energy from sunlight and make sugar. Plants use the energy in the sugar to grow.
