LIVING THINGS AND
VITAL FUNCTIONS 1.1.
What are living things: All living things carry out three
processes that are called vital functions 1.1.1.
NUTRITION: Living things obtain the matter
and energy taking substances from the environment. Nutrition requires intake
of food and oxygen. 1.1.2.
INTERACTION: Consist of perceiving changes on
the environment, called stimuli, and reacting to them 1.1.3.
REPRODUCTION: To produce descendents with the
same characteristics to ensures the perpetuation of the species 1.2.
Chemical Composition All living things are made of similar compounds 1.2.1.
Inorganic compounds have simple molecules
(Water and minerals) 1.2.2.
Organic compounds are complex molecules
made of C,H,O,N,P,S. They are sugars, Lipids, Proteins, Nucleic Acids and
Vitamins. 1.3.
Cells All living things are made of cells. 1.3.1.
Types
of organisms 1.3.1.1. Unicellular organisms. Just one cell
or colony 1.3.1.2.
Multicellular
organisms: Groups of cells that work together as whole Cells, tissues, organs, systems. |
1. Structures Objective 1.1. To describe the parts of something
(There is, There are, It has,,..) as well as the properties of the elements
(Cell, nucleus, vacuole …) Levels of organization of living things

2. Cells A cell is the basic unit of life and the structural
and functional unit of all living things 2.1.1.
Parts of the cell 2.1.1.1.
Plasmatic
membrane (Cell wall) 2.1.1.2.
Cytoplasm:
Ribosomes, Lysosomes, Vacuole, Chloroplast, Mitochondria, Centrioles. 2.1.1.3.
Genetic
Material – DNA
2.1.2.
Types of cells 2.1.2.1.
Prokaryotic cell: DNA floats in the
cytoplasm. 2.1.2.2. Eukaryotic cell: DNA is found inside
an organelle called the nucleus 2.1.2.3. Plant cells: Chloroplast, Vacuole,
cell wall 2.1.2.4. Animal cells: Centrioles, cilia

4. PLANT NUTRITION Plants are multicellular organisms. Most of them
have organs specialised in exchanging matter with the environment and in
transporting substances 4.1.

Transportar sustancias 4.4.1.
Xilema Transporta la
savia bruta de la raíz a las hojas. 4.4.2.
Floema: Transporta
la savia elaborada de las hojas al resto. 4.5. Crecer 4.5.1.
Meristemos: Sus
células se dividen muy deprisa (en las yemas de los tallos y en las raíces).

8. ANIMAL NUTRITION:
CIRCULATION 8.1.
Transportation of substances §
Simple animals interchange substances directly from the outside
environment. §
Other animals have a circulatory system with: ·
Circulating liquid: Blood ·
Vessels (veins, arteries) ·
Pump (heart): Moves the liquid
thanks to contraction and dilation movements
