Vital Function of Plants

Now, we are going to watch the video about vital function....

PARTS OF THE PLANTS

Get Ready Scientists!

Have you ever looked closely at flowers?

As a scientist, examine some flowers and in your notebook or journal,

draw, sketch or write the similarities and differences you observe.

Here are some parts of flowers that you may or may not have discovered:

Petals – are colorful, soft and brightly colored to attract insects and bugs.

Pistil – as the stalk in the center of the flower.

Stamens – are the stalks surrounding the Pistil.  

Ovary – is the pouch at the bottom of the Pistil.

Anther – is a sac at the top of each stamen.

Pollen – is the sticky stuff or dust on the Anther. 

Sepals – are the small leaves around the bottom of the flower

Seeds – from the ovary travel down the pistil.

Here is a diagram that my son made of the different parts of the flower. . . 

Now draw and label the parts of the flower so that we will

know what the parts are when we dissect the flower.

Take your flower and slowly and gently take it apart.

Put the pieces of the flower where they belong on your diagram,

or put them on a separate paper and label them again!

Now you can teach others the scientific parts of an everyday flower!

THE REPRODUCTION FUNCTION

Living things reproduce.


 * SEXUAL REPRODUCTION IN ANIMALS

    It has three phases:

•  1st Production of gametes
•  2nd Fertilization
•  3rd Development of the embryo

  SEXUAL REPRODUCTION IN PLANTS

  Reproductive organ : Flower

  The flower has got four main parts: 

1. pistil
2. stamen
3. calyx
4. corolla

Reproduction in flowers has got three phases:

1. Pollination and fertilization
2. Formation of the fruit and seed
3. Germination of seed.

SEXUAL REPRODUCTION IN PLANTS

Pollination

Pollen is transferred from a stamen to a stigma. The stamen is the male organ in a flowering plant and the stigma is the female part.

It is helpful to review the parts of flowering plants.

Growth of Pollen Tube

A pollen tube develops to carry the pollen downward.

Pollen travels from the stigma, down the style, and into the ovule of the plant.

Fertilization

The male gamete (pollen) unites with a female gamete (ovule) to form a seed. The seeds are the embryo of the plant.

Fruit Formation

The ovary ripens and forms a fruit. The fruit may contain a single seed or multiple seeds.

Seed Dispersal

The fruit is carried away from the parent plant by wind, animal or expulsion.

Germination

If the seed is embedded in the right kind of soil, it will germinate. A new plant grows out of the seed. A stem reaches upward, and roots go downward into the soil.
