Hello everyone!

Hi, as you already know, my name is Ana and I am going to be your science teacher this year. I created this blog to make our classes more interesting as well as you can improve the subject at home.

Book online

I want to remind you that you can work at home with the material that you can find online with the code of your book. It is very useful, so you should try to get the most out of it. Repeat the listenings again to improve at home.

Vital functions

NUTRITION: to obtain the matter and energy.

INTERACTION: interact with their environment.

REPRODUCTION: to have descendants. 

NUTRITION

Organisms need matter and energy. 

There are two types of nutrition depending on the type of matter obtained:

• Autotropic nutrition: they obtain inorganic materials from the environment which they transform into organic material. It is typical of plants, algae and some bacteria. Through the process of photosynthesis, they create organic matter. This process takes place in the chloroplasts. 

• Heterotrophic nutrition: they have to take organic matter from the environment. Examples: animals, fungi, protozoa and some bacteria. 

Depending on the type of energy obtained, there are: 

• Cell respiration: consists of using organic matter to produce energy. This process takes place in the mitochondria. During cell respiration cells take in O2 and they release CO2. 

• Fermentation: for example yeasts.
