This blog will guide you through your Biology course. It will help you to find all subjects we will be reviewing and it will make easy for you to find some links to develop some skills you have learned.

What is Biology?

Have you ever wonder about living things?
Biology is a Science studying the concepts, principles and theories that allow people to understand living things and their natural environment: the life itself. 

So, Biology is a Science that study living things and thier interaction with their environment. 

Let´s look at the Biology´s defintion at the dictionary: 


How many kinds of living things do you know?

Look around you.  What do you see? A classmate?  Look out of the window or what will you see if you´ll go for a walk to the park? 
You´ll see: trees, grass, plants, dogs, cats, bugs, birds and probably many other children and adults. 

But, life extends much further than what you can see. 
Everywhere around you, all over your iPad, the monitor of your computer, your desk, the walls, the floor, and even your skin, you can find billions and billions of tiny microscopic lifeforms.

Most importantly, How do you know they are alive?
What do all living things have in common? 
How do you know a human being or an animal or a tree is a living thing and a stone is not?

Charaterisitics of Living Things

1. Organized: organisms are made of one or more cells
2. Reproduction: organisms produce offspring
3. Growth and development: increase in the amount of living material and formation of structures. It includes: nutrition and excretion
4. Response to stimulus (senstivity): organisms detect and respond adjusting to stimuli from the environment (air, water, weather)
5. Adaptation: any inherited strucutre behaviour or internal process that enables an organism to respond to environmental factors and live to pass it to their offspring.
(Mrs gren: is an acronym which stands for all 7 charactteristicas of living things: M for movement, r for respiration, s for sentivity, g for growth, r for reproduction, e for excretion and n for nutrition).

Living things are made of cells. 
These cells are basic buikding blocks of life. 
As an exaple, think of a sandcastle. If you see it from the distance it will look like a smooth building. But as you get closer you begin to see is made of millions of tiny sand grains.  

Where do they live? What they are like? How they relate to each other? How they behave?

We will learn about all these questions along the Biology´s course, but for now let´s start with how living things are classified.

The first big division of living things in the classification system is to put them into one of six kingdoms. 

1. Protista

2. Bacteria and 3. Arachae bacteria are grouped into Monera Kingdom

4. Fungi

5. Plants

6. Animals

These classification of living things into kingdoms are based on what an organism's cells are like.

Cell types:

Prokaryote= include living things which cells DO NOT HAVE nucleus. ONLY MONERA and ARCHAEA KINGDOMs are INCLUDED

Eukaryote= is including living things, which cells DO HAVE nucleus. KINGDOMS INCLUDED: ANIMALIA, PROTISTA, PLANTAE AND FUNGI.
