PARTS OF THE PLANT. FUNCTIONS.
ROOTS. THEY HAVE TWO FUNCTIONS:
-ABSORB THE WATER AND MINERALS THAT THE PLANT NEEDS TO GROW.
-FIX/SUPPORT THE PLANT INTO THE GROUND.
STEM. IT HOLDS THE PLANT AND CARRY THE WATER AND MINERALS FROM THE ROOTS TO
THE REST OF THE PLANT.
LEAVES.
USE THE SUNLIGHT TO MAKE THEIR OWN FOOD. IN THE LEAVES THE
PHOTOSYNTHESIS TAKES PLACE. THE PHOTOSYNTHESIS IS THE PROCESS IN WHICH THE PLANTS
MAKE THEIR OWN FOOD.
PLANTS NEED TO GROW: WATER AND MINERALS, SOIL, SUNLIGHT AND CO2.
FLOWER. PARTS OF A FLOWER. PARTES DE LA FLOR.
LA FLOR TIENE DOS PARTES. PARTE MASCULINA Y PARTE FEMENINA.
LA PARTE MASCULINA SE LLAMA ESTAMBRE. EL ESTAMBRE ESTÁ FORMADO POR LA ANTERA Y
EL FILAMENTO. EN LA ANTERA ESTÁ EL POLEN. UN INSECTO COMO PUEDE SER LA ABEJA Ó EL
VIENTO ARRASTRA EL PÓLEN.
EL POLEN LLEGA A LA PARTE FEMENINA QUE SE LLAMA PISTILO. EL PISTILO SE DIVIDE EN TRES
PARTES: ESTIGMA, ESTILO Ó TUBO POLÍNICO Y OVARIO. EL ESTIGMA RECIBE EL PÓLEN. EL
ESTILO Ó TUBO POLÍNICO ES EL CONDUCTO QUE UNE EL ESTIGMA CON EL OVARIO. EL POLEN
BAJA POR EL ESTILO Y LLEGA AL OVARIO EN EL CUAL LOS ÓVULOS CRECEN. ALLÍ SE CREA LA
SEMILLA.
OTRAS PARTES DE LA FLOR SON:
PÉTALOS (SON COLORIDOS Y BRILLANTES Y ATRAEN A LOS INSECTOS)
SÉPALOS. FORMAN LA PARTE MÁS EXTERNA DE LA FLOR Y PROTEGEN A LA FLOR CUANDO ES
SOLO UN CAPULLO.

Parts of a flower
A flower is the reproductive part of a plant. They play an important role
in making seeds. There are two types of flowers: – Perfect Flower and
Imperfect Flower. A perfect flower has either all male parts or all female
parts but not both in the same flower. An imperfect flower has both the
male parts and female parts in a single flower. Flowers come in many
different shapes, sizes and colours. However, most have a similar basic
structure. A flower consists of many different parts.
Male Parts: –

Stamen: – This is the male part of a flower. It is made up of
filament and anther. This part produces pollen for the plant. The
number of stamen is usually equal to the number of petals in the
flower.

Anther: – It is a part of the stamen. Anther produces and
contains pollen. It usually sits on top of a long stalk that looks like
a fine hair.

Filament: – The fine hair like long stalk is called filament. Anther
is placed on the top of filament in a flower.
Female Parts: –

Pistil: – It is the female part of the flower. Pistil is consists of the
stigma, style and ovary. One pistil is

constructed of many structures that are rolled like leaf.

Stigma: – This female part of the flower is the sticky bulb that
you see in the centre of the flower. It receives the pollen grains.
On stigma, those pollen grains can germinate.

Style: – Another female part of the flower. Stigma is placed on
the top of style.

Ovary: – The part of the plant, usually at the bottom of the
flower, that has the seeds inside and turns into a fruit that we eat.
The ovary contains ovules.

Ovules: – A part of the ovary that becomes seed.
Some other parts of a flower: –

Petal: – The most colourful and bright part of the flower. They
attract pollinators.

Sepal: – Sepal in a flower looks like little green leaves that cover
the outer part of a flower bud to protect the flower before it
opens.
