4TH GRADE-UNIT 2-C.B 28-29
Most plants reproduce with flowers.
Flowers become fruits.
Fruits contain seeds.
New plants grow from seeds.
PARTS OF A FLOWER
1- The PISTIL is the female part of the flower.
It is shaped like a bottle.
It contains the OVARY.
2- The STAMENS are the male part of the flower.
They produce POLLEN.
3- The COROLLA consists of coloured parts called PETALS.
4- The CALYX consists of small green leaves called SEPALS.

THE LIFE CYCLE OF A FLOWERING PLANT
1- Pollen is produced in the stamens.
2-The pollen reaches the pistil of another flower and travels
to the ovary.
3-The ovary develops into a fruit. The fruit contains seeds.
4-When a seed falls to the ground, a new plant begins to grow.

FRUITS
-Each fruit contains one or more seeds.
-There are two types of fruits: fleshy fruits and dry fruits.
FLESHY FRUIT: juicy and soft. They contain a lot of water.
DRY FRUIT: They contain little water.
SEEDS
-They contain a very small plant called an EMBRYO.
-They also contain food to keep the embryo alive.
-When the seed fall to the ground and finds enough moisture, a new plant begins to grow. This is called GERMINATION.
-The seed takes in food. A young plant, called a SEEDLING, starts to
develop.
