Photosynthesis.

Green leaves make the energy the plant needs to live.

Water and minerals come from the soil, through the roots; carbon dioxide from the air and sunlight from the sun,through the leaves.

All these elements are transformed into energy(in the form of glucose or sugar), the food the plants needs to grow and reproduce.

At the end of photosynthesis oxygen is released (liberated, set free).

Have a look at these pictures:

Life cycle of a plant.

The fruits contain the seeds of the plant:










The seed falls in the soil and germinates:



A new plant, its name is seedling, grows after this process:



This new plant grows and has flowers. Insects pollinate these flowers and we will have new fruits.

Have a look around you!

Plants are very different.


Some plants have flowers:



These are almond trees.





Some plants have thin leaves:



This is a palm.





Other plants, such as the fig tree, have broad leaves.




It is important to see if leaves are flat or they are not.

Some plants produce fruits the animals and human beings can eat, see this apple tree loaded with apples:

Parts of a plant.


The main parts of a plant are: roots, stem, leaves and flower.












Roots: they hold the plant in the ground, they also take water and minerals from the soil.

Stem: it carries water and minerals from the roots to the leaves.

Leaves: they use the sunlight energy, carbon dioxide, water and minerals to make the plant's own food.

Flowers: they produce seeds. New plants will grow from the seeds.

The nervous system.

When we see, hear, touch, smell or taste the information goes to the brain.





This information goes to the brain through the spinal cord.




The parts of the nervous system are: the nerves, the spinal cord and the brain.

The sense of smell.

We use our nose to smell things.




The nose: The two external cavities are called nostrils and take the air into the nose. Behind the nostrils we find the nasal cavity.
