• BUAH
• FRUIT
• Umumnya buah berkembang dari alat kelamin betina
  (putik) pada tumbuhan biji, yaitu bagian bakal
  buahnya jika terjadi pembuhan. Pembuahan yaitu
  proses meleburnya sel telur dengan sperma di
  dalam putik. Berdasarkan pembentukanya, buah di
  bagi menjadi dua macam ,yaitu buah sejati dan
  buah semu.
•  Commonly fruit develops from female reproduction
  organ (pistil) in seed plant. 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.

• Jenis-Jenis Buah
• The Kinds of Fruit
• Berdasarkan pembentukanya, buah di bagi menjadi
  dua
• macam, yaitu buah sejati dan buah semu.
• Buah sejati adalah buah yang dibentuk oleh
  seluruh jaringan bakal buah. Buah sejati di
  temukan pada buah pepaya, durian, mangga, tomat,
  dan sebagainya.
• 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.

• Buah semu adalah buah yang dibentuk bukan hanya
  dari bakal buah saja,tetapi juga berasal dari
  bagian-bagian bunga yang lainya. Contohnya adalah
  manggis, jambu mede, ciplukan dan nangka. Jambu
  mede buahnya berasal dari tangkai bunga yang
  membesar. Nangka, buahnya berasal dari
  kelompokbunga yang tumbuh menebal dan berdaging.
•  
• 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.

• Biji terbentuk dari hasil pembuahan yang terjadi
  di dalam bakal buah. Bakal buah dibedakan menjadi
  dua, yaitu bakal biji yang terbungkus oleh daun
  buah, seperti biji mangga, rambutan, salak, dan
  bakal biji yang tidak terbungkus oleh dun buah,
  seperti pada pakis haji.
•  
• 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 pakis haji (cycas rumphii).

• Pada biji terdapat calon tumbuhan baru (lembaga)
  dan putih lembaga (endosperm). Lembaga terdiri
  atas tiga bagian, meliputi akar lembaga
  (radikula), batang lembaga (cauliculus), dan daun
  lembaga (kotiledon). Cauliculus dan calon daun
  dinamakan juga putik lembaga.
•  
• Within the seed, there are embryo and endosperm.
  Embryo consists of three parts, rootlet
  (radicle), little stalk (cauliculus), and seed
  leaf (cotyledon). Culiculus and leaf seed are
  called plumule.

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

12
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
13
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
14
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
15
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.

16

• 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.
