Plants has got different parts. They are: -Reproductive organs -Nutrition parts
The main nutritive parts are: -Stem -Leaves -Roots
The stem takes and storages nutrients that roots recolected. It gives the nutrients to all the plant. The stem also support the fruit, leaves and flowers.
Roots are the most important parts of each plant. They take different nutrients and water from the soil. They also give support to the plant.
Leaves take the carbon dioxide and sunlight to mix it with nutrients and water to make food.
Plants perform photosyntesis to give food to all the plants’ body: 1st: Roots take the nutrients. 2nd: Nutrients pass to the stem.This mixture is called ‘raw sap’. 3rd: Leaves take carbon dioxide (CO 2 ) and sunlight and mix it with the raw sap to make elaborated sap. 4th: Elaborated sap passes to the stem to feed all the plant.
During the night, plants take oxygen and expel carbon dioxide.
AND HOW THEY WORK
Flowers have all the reproductive organs of the plant: -Pistil -Corolla -Calyx -Stamen
The calyx is made up of a lot of sepals. They protect the petals and the inner parts of the flower.
The corolla is made up of petals. It also attracts insects in order to pollinate the flower.
Pistil is the female organ of the plant. It has three parts: -Stigma: It’s where pollen grains enter. -Style: It’s where pollen travels to the ovary. -Ovary: It’s full of ovules and is where pollen and the ovule join to germinate the seed with the fruit.
The stamen is the male part of the plant. It has two parts: -Filament: It supports the anther. -Anther: It’s where the pollen grains are.
POLLINATION AND CROSS-POLLINATION
This type of pollination is the most standard; normal pollination. When the wind blows, pollen travels with it and some pollen grains fall inside other plants pistil. This process is called ‘Pollination’.
In this type of pollination, insects are attracted by the petals. When they are on the flower, pollen sticks to their feet. When they fly away, some pollen falls from their feet to the flowers pistil. This process is called ‘Cross-pollination’.

-How we call the male reproductive organ? We call it ‘Stamen’ -What’s the part that extracts oxygen? They are the leaves. -What part protects the flowers petals? The calyx or the sepals (more or less the same)
